Can't access the development server

[Ben]

Hi,

I'm completely new to python and Django, although fairly familiar with
programming and web servers in general.

I'm struggling to get Django up and running, at the moment, and I'd be
really grateful if someone could help.

I'm following this tutorial, after having successfully installed
Django:

http://docs.djangoproject.com/en/dev/intro/tutorial01

I start the development server using:

python manage.py runserver

which seems to work ok:

Validating models...
0 errors found

Django version 1.1 pre-alpha SVN-9479, using settings
'prototype.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

In fact, on that server, I can telnet to the development server fine.
However, if I try to access it in my browser, nothing happens. The
access doesn't show up on the server output and the browser fails to
connect at all. I've tried starting it on different ports, with no
success. I am able to access the thing on port 3000, although at the
moment I'm not quite sure what this is... As far as I know there are
no firewalls between me and the server (it's a shared hosting server
with Site5).

I'm assuming that when I try to connect to port 8000 this will go
directly to the development server and apache settings etc should be
irrelevant? How about python settings? Is it possible that I've got
something misconfigured that would cause this behaviour?

Any more information I can provide?

Thanks in advance!

Ben

Re: Do you recommend "Practical Django Projects"?

[Ben]

I recently read both and went thru all the examples in Pracitical
Django Projects.  It was a bit tough at first because some of it is a
little dated, but actually figuring out how to adapt it to 1.0 is
actually a good exercise in itself (learning how to debug and actually
understanding how things work).  I found learned a lot more this way
than if everything went smoothly by coping the examples.

There is also a doc that specifically points out what are backwards
incompatible changes

Re: Tutorial 2 - Template Dirs

[Ben]

Hey this might be a question I can answer - I'm a NKOTB too.

The easiest way is to modify the "title" and "branding" blocks in the
base_site.html file.  This would change the name for the admin across
the site, as far as I know.  It should live in (in your case) /home/
divesh/projects/myproject/templates/admin/base_site.html - looks like
you've already copied that file from the django site-packages
directory.

--

{% extends "admin/base.html" %}
{% load i18n %}

{% block title %}{{ title }} | {% trans 'Django site admin' %}{%
endblock %}

{% block branding %}
{% trans 'Django administration' %}
{% endblock %}

{% block nav-global %}{% endblock %}

syncdb doesn't updated database after adding null=True to an IntegerField

[Ben]

I'm using the admin site. I noticed that I couldn't leave an
IntegerField empty even when I had "year = models.IntegerField
(blank=True)". I googled and found out I should set null=True as well.
I did this, ran syncdb, and it didn't fix the issue.

I am using sqlite3 with a temporary database. I restarted my machine,
so that the database was deleted, ran syncdb, and the issue was fixed.
I tested again and it looks like once the database and tables are
created, adding null=True to an IntegerField and running syncdb won't
actually update the database.

Is syncdb supposed to fully sync the database to the model
definitions? If so I would call this a bug.

Comments?

Quick Newbie Question - reverse ManyToMany in admin site

[ben]

Hi all,
I've got a model with a plain many-to-many relationship (no
intermediate model) and want to edit the relationships in the admin
site. By default the multiple select box only appears on the admin
page for the model that defined it, however I'd like to be able to
modify the relationships the other way around too.

e.g. for items in groups, I'd like to have
item admin page allowing a multi-select on the groups related to it
group admin page allowing a multi-select of items within the group

The admin docs describe the problem but only show the solution for the
more complicated (intermediary model) case:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#working-with-many-to-many-intermediary-models

Is there an easy way to do what I want? The solutions I've found have
all been for some complicated syncdb and model definition solutions
that seem a bit overkill for just showing the relationship in the
admin site.

Cheers
Ben

default settings for applications

[ben]

I'm wondering if a convention exists for dealing with applications
settings.  I'm thinking of having the default  settings to be
specified in my application in a default_settings.py file but be
overridden by any values in DJANGO_SETTINGS_MODULE.  I can do this
easily enough, but it feels like something that might be already
standardised.  Does a convention exist, and if so what is it?

Re: default settings for applications

[ben]

Thanks for the answer.
In particular I'm wondering about apps that will be shared by several
projects.  The
default_settings.py would then be the values of the settings if the
projects don't
override these settings in their DJANGO_SETTINGS_MODULEs.  Effectively
I'm planning
on using something like django.conf.settings but where the defaults
are in the application
itself rather than in django.conf.global_settings.  It sounds like
there's no convention
for something like this.

Deleting objects in Admin - Circular References

[ben]

If I have two models that contain foreign keys to each other, e.g.

class Quiz(models.Model):
current_question = models.ForeignKey('Question')

class Question(models.Model):
quiz = models.ForeignKey('Quiz')

, where there are multiple questions in each quiz, but only one is
current.

When I then delete a quiz object in the admin interface the
confirmation page show a long list of dependent objects of the form:
- Quiz
- Question
- Question
- Question
- Quiz
-Question
-Question
-Question
, and so on.

The delete works fine, I just find the confirmation page aesthetically
unpleasing.  Is there a way to exclude circular references from the
displayed list of dependent objects?

Puzzling filter/annotation of queryset based on count

[ben]

Hi all, have been having trouble with figuring out how to construct
more complicated filters on query sets, especially when mixing them
with annotations.

Specifically, I have:

An Item, which has one of many ItemTypes
A Collection, which contains many Items.

What I want to construct is a queryset containing a set of
Collections, with a field (annotation) with the Count of items
belonging to that collection with a specific ItemType

So something along the lines of Collection.objects.annotate
(item_count=Count('item')).filter(item__itemtype=1).filter
(item_count__gt=0).all()

however I can't figure out the correct configuration of annotations
and filters to get back what I want! I'm sure this will take a
seasoned djangonaut a few seconds to figure out so any help is
appreciated!
Cheers

Generic Many-To-Many without GenericRelations

[ben]

Generic Many-To-Many Relationships

I have a collection class which contains arbitrary objects using a
Generic Many-To-Many relationship.


class Collection(models.Model):
name = models.CharField(max_length=VERBOSE_NAME_MAX_LENGTH)

def member_objects(self, klass):
"""Returns a QuerySet of all objects in the collection of the
given class."""
# Should be stuff here.
pass


class ObjectInCollection(models.Model):
collection = models.ForeignKey(Collection)
content_type = models.ForeignKey(ContentType)
object_id =models.PositiveIntegerField()
object = generic.GenericForeignKey()


class ExampleObject(models.Model):
# Stuff here
# I don't want to rely on the following generic relation.
oics = generic.GenericRelation(ObjectInCollection,
   related_name='example_object')


My problem is the member_objects method.  If I give all the object
classes that might be included in the collection a GenericRelation (as
in ExampleObject) then I can use:

   def member_objects(self, klass)
   return klass.objects.filter(oics__collection__id=self.id)

But I don't want to rely on having this in all the classes (because
the classes might be in other applications or there might be multiple
collection classes).

I could use a klass.objects.raw custom SQL method but that wouldn't
return a QuerySet which I would prefer.

Is there a way to do this that:
  1) does not require a GenericRelation in all classes and
  2) returns a QuerySet?

Cheers.

dynamic inlines (svn #12297) and older template logic breaking down

[ben]

I was updating to the latest SVN and encountered some odd behavior
with a custom gallery image admin inline template. I've narrowed it
down to some dynamic inlines development released in 12297. The
problem is that I don't really know if it merits a feature request or
if I'm missing something.

The issue boils down to the "add new" loop with "extra" set to 1 (only
one image can be added per save), specifically the use of the
"original" property in differentiating between existing and new
gallery images. The goal is to be able to determine which are bound to
the database from those that are adds.

{% for inline_admin_form in inline_admin_formset %}
{% if inline_admin_form.original %}
{% else %}
{% include "admin/edit_inline/gallery_image.html" %}
{% endif %}
{% endfor %}

The above template admittedly has the problem where the underlying
django can not create other formsets which are not "original" without
it breaking, and this is indeed what seems to be happening.

In a fresh gallery admin with no images saved --
#12296
1 gallery image add option - galleryimages-0-image only
#12297
2 gallery image add options - galleryimages-0-image and galleryimages-
__prefix__-image

Under current SVN is there a way to excude the __prefix__ instance
within the template? If not, would it be worth submitting a feature
request to enable the ability to discern between the two kinds of non-
original inlines?

Thanks!
Ben

Re: dynamic inlines (svn #12297) and older template logic breaking down

[ben]

Update - it seems that excluding the prefix elements can be done by
excluding forloop.last in addition to formsets that are data bound.
the stacked.html template in contrib mirrors this. While it doesn't
seem to be the futureproof solution I'd hoped for, it does work.
Perhaps the best move would be to allow the 1.2 release to settle out
and revisit the logic later.

workaround:

{% for inline_admin_form in inline_admin_formset %}
{% if inline_admin_form.original or forloop.last %}
{% else %}
{% include "admin/edit_inline/gallery_image.html" %}
{% endif %}
{% endfor %}

run single regression test from test suite

[ben]

I haven't been able to work out how to run a single regression test
from the test suite.

I would have thought that

./runtests.py --settings=test_sqlite
regressiontests.generic_relations_regress.tests.GenericRelationTests

might work.  But it expects tests of the form app.TestCase.  Since
these tests aren't in an app I'm not sure how to run them
individually.

How to use CommaSeperatedIntegerList with CheckboxSelectMultiple

[ben]

Hi, I am new to Django. I am currently using the latest Django 1.2
from trunk. I am trying to store a list of values in a
CommaSeperatedIntegerList. I would like to use a
CheckboxSelectMultiple widget to render and select the values in the
list. I have setup my code like so.

SOME_CHOICES =  (('1', 'ch1'),('2', 'ch2'), ('3', 'ch3'),('4',"ch4"),
('5',"ch5"),)

class QandA(models.Model):
q1 = models.CommaSeparatedIntegerField(choices=SOME_CHOICES,
max_length=100, null=True,blank=True)


class QandAForm(ModelForm):
  class Meta:
  model=QandA
  fields=['q1']
  widgets={'q1':forms.CheckboxSelectMultiple,}

The form renders properly but I get the following validation error
after posting.

"Select a valid choice. [u'1'] is not one of the available choices."

The same thing happens when I attempt to use SelectMultiple as the
widget. Can anyone tell me what I am doing wrong? I have googled about
but have not been able to find anything describing how to handle this.

Thanks, Ben

Re: How to use CommaSeperatedIntegerList with CheckboxSelectMultiple

[ben]

So what your saying is that I'm not using CommaSeperatedIntegerField
for its intended purpose? I should think about writing a set of custom
fields? I just assumed support for this type of thing was built in. I
will keep hunting.

Re: How to use CommaSeperatedIntegerList with CheckboxSelectMultiple

[ben]

Sorry. I pasted code that I was experimenting with. I thought maybe
the validation code was looking for strings because that is what the
error code said it was looking for. Before that I had been using
integers and that doesn't seem to work either. I am wondering if this
is a bug in Django 1.2. I hunted around on Django snippets as Bill
Freeman suggested and found the following code 
http://www.djangosnippets.org/snippets/1200/
for a custom multiple selection field.

I inserted it into my app and it doesn't want to validate the
selection either. In fact it returns a validation error message
similar to what I received from CommaSeperatedIntegerField and
CheckboxSelectMultiple. "Value [u'1'] is not a valid choice."

Not sure what is going on. Any insights would be appreciated.

Re: How to use CommaSeperatedIntegerList with CheckboxSelectMultiple

[ben]

Either I don't understand how CheckboxSelectMultiple works or there is
a bug in Django 1.2. I have tried the following custom multi select
fields I have found around the web.

http://www.djangosnippets.org/snippets/1200/
http://www.davidcramer.net/code/181/custom-fields-in-django.html

Out of desperation I tried using a ManyToMany field and all produce
the same validation error when used with either CheckboxSelectMultiple
or SelectMultiple.

'Select a valid choice. [u'1', u'2', u'3', u'4'] is not one of the
available choices.'

This happens regardless of the number of choices, types of the choices
tuple values, or the model field type.

Can anyone point me to an example that demonstrates how to properly
use these fields.

Thanks,
Ben

Module loading error in django trunk.

[ben]

Hi All,

After a recent svn update to my copy of Django/trunk I’ve been getting
a persistent error relating to module loading (see below). I am able
to create the same error from many but not all views/requests.

Interesting, when I run my code against a slightly older version of
Django trunk (at Rev. 13079) I don’t get these errors.

Is this a bug, or have I missed some backwards incompatible change?
I’ve searched around and came up with nothing? Any insights or
suggestions much appreciated.

kindly,
Ben.

I have performed a system wide root level expunge of all .pyc's
and a svn up to 1.2.1 pre-alpha SVN-13294, but this sporadic error
still persists.

The same view will not always trigger the error, sometimes the view
function will run successfully, others not.

If i walk though the procedure with pdb (and if i understand what it
is telling me) it seems to indicate an issue with loading taglib and
perhaps one of my apps called 'featured'. but why would this app now
fail to be loaded properly, when previous to django Rev13079 it loaded
fine?

Below is a more full (read lengthy) stack trace. and some pdb output.

If there is more information that i can provide to assist please let
me know, and how to gather it.

Thanks in advance,
Ben

hyperlinks within admin interface

[Ben]

Is it possible to mess with the __unicode__ method of a model to
enable a model instance to return a link to itself when viewed within
the admin interface? What I want is for there to be a link on an item
in an inline which takes the user to it's own edit page.

For example, I have a Survey system where we have questionnaires with
pages and questions. I use a questions_in_page model to store extra
attributes for the many_to_many, and this is what appears as an inline
in the Page admin view (i.e. you can't edit the question itself from
the Page admin view, only the object in the link table). I'd like to
be able to create links directly to the questions...

Any suggestions much appreciated.

Ben

Deploying Django on a server with mod_userdir

[Ben]

Hi everyone, I'm just starting out with Django and really enjoying it.
For a project I am trying to install it on an Apache server at school
with multiple users. The userdir module is enabled such that users can
create their own websites. I'd like to allow some of these users to
tinker with Django.

I have administrator access but need to make it easy for regular users
to deploy their own Django websites if they are so inclined. I have
installed mod_wsgi and mod_userdir, and configured everything as such:

/home/username/django/  is where their Django 
application lives
/home/username/django/apache/   contains the WSGI interface file
/home/username/www/ is their website directory
/home/username/www/media/   is where their Django media 
files live

example.com/~username/  is their static website
example.com/~username/django/   WSGI mounts the Django application at /
~username/django/

The problem I am having is actually accessing my test Django website.
When I attempt to access example.com/~username/django/admin/, I get
the Django 404 debug message. So, I know it's at least running
correctly. I've uncommented the three lines from urls.py to enable
admin access and added the django.contrib.admin package to
INSTALLED_APPS in settings.py. I ran syncdb.

I've tried configuring urls.py to map the admin to ~username/django/
admin and django/admin as well, with no luck. If anyone could help me
out I'd really appreciate it!

Thanks,

Benjamin Webber

NullBooleanField default to unknown

[Ben]

I have a NullBooleanField that I would like to show up in my admin
interface as radio buttons with unknown selected by default.

# I have the following simplified files

## models.py ##
class Value(models.Model):
presence = models.NullBooleanField(default=False)

## admin.py ##
PRESENCE_CHOICES = ((True, 'True'), (False, 'False'), (None, 'None') )
class ValueAdmin(admin.ModelAdmin):
formfield_overrides = {
models.NullBooleanField: {'widget':
RadioSelect(choices=PRESENCE_CHOICES)}
}
admin.site.register(Value, ValueAdmin)

This behaves very closely to what I desire, but I don't know what I
could replace the False with in:
presence = models.NullBooleanField(default=False)
in order to make it behave as I would like.

Thanks so much for your time,
Ben R.

Django will run all tests imported from the tests module. Check out the 
__init__.py in django/contrib/auth/tests and you'll see it imports all of 
the tests from the other files in the test dir.

Django Success Story

[Ben]

If you'd like to read about the recent success of a summer project
involving Django, read on.

I've been playing with django in my spare time for a couple years.
I've written a simple blog app, and have half-finished a few sizeable
apps, one of which will be put on a vps by the end of the semester.

This past summer, my fiance worked in an REU to develop an online
learning module for a graduate course. I promised to help her a bit
with the details if she chose to use Django. By the end of the 8 week
summer project, all the code and templates had been written,
documented, tested, and debugged, and most of the content was in
place. The first 2-3 weeks were spent learning the content of the
course, and the last week was spent installing everything on her
supervisor's machine and teaching her how to create the rest of the
content. (MySQL on windows can be annoying.) So, about 20 hours per
week times about 4 weeks produces a debugged cross-platform webapp.

Anyway, my fiance just got an email from the supervisor to say that
the learning module was recently used in the course, and just about
everybody loved it. There were no technical difficulties, the
professor was impressed, and the TA said it would be a good tool
throughout the class.

Thank you, Django!

404 on admin media files and mod_python

[Ben]

Hello

The issue of how to serve the admin media files using mod_python has been dealt 
with several times before, and AFAICS I've followed the advice given (and the 
documentation), but I still get a 404 on the admin media files.   I've already 
removed "Apache expert" from my CV.
Any suggestion appreciated.   

#settings.py:
ADMIN_MEDIA_PREFIX =  '/admin_media/'

#urls.py:
urlpatterns = patterns('',
 (r'^requests/', include('mysite.requests')),
 (r'^admin/', include('django.contrib.admin.urls')),
 (r'^admin_media/', include('django.contrib.admin.urls')),
)


Apache config:
Alias /admin_media/ /var/www/mysite/admin_media

   SetHandler None


#Apache log file (Result of above config)
GET /admin_media/css/dashboard.css HTTP/1.1" 404 3571 "http://mysite.com/admin/";

Thanks for your reply. I agree, but desperation made me doubt what I knew

I did indeed copy the media files to the web root.  However, aliasing them to 
the django source makes no diffference:
Alias /admin_media/ /usr/lib/python2.4/site-packages/django/contrib/admin/media/

It still gives me a 404

Thanks for your reply.  I now have the trailing slash in both places, but still

There is nothing of interest in the error log.  The slashes and everything else 
look OK in the access log:
GET /admin_media/css/dashboard.css HTTP/1.1" 404 2054

Yes, this seems to be the problem, because if I visit

an Apache 404

I've put the admin_media stuff below the Django  block and it now 
works fine
Thanks!

website template compatible with django

[Ben]

Hi all,
I am a total Django newbie.  Hence the probably silly questions:
There are professional-looking website templates for sale in several
places (templatemonster, etc).
Can those be used easily with Django ?
Do they need to be designed specifically for Django ?  Do you know of
any vendor that does it ?
If not, what to look for in a template order to make sure it will be
relatively easy to use with Django ?
Thanks a lot!

Detecting changed fields when saving an object

[Ben]

I'm trying to create an audit trail for a particular model, capturing
all changes made on the objects.

My immediate idea was to subclass the save() method on the model and
compare the values both before and after calling the parent save
method. This would work, but it would mean I would have to update this
whenever a new field was added to the model which is both non-DRY and
rather tedious.

Is there any django way of doing this? Something like:

def save():
  for all fields in this object:
if field is now different:
  do audit here
  super(blah, self).save()

Cheers,
Ben.

If I could have described the type of answer I wanted, it would have
been exactly that :)

Actually, that's given me ideas but I can't seem to work out how to do
what I want. That works by simply storing the values after the change
each time the model is updated. However, I don't seem to have both the
before and after values in a single method, they are the same before
and after the parent save() call.

Using signals seems to have this problem as well, I can't compare the
before and after values at any one time.

I don't specifically need the before value, I need to know which of
the fields have changed.

Re: geodjango apache vs lighttpd

Yup as you say, it was apache + mod_python switched to lighttpd +  
fastcgi. Sounds like it could well be mod_python / Apache issue at the  
root of it.

Admin interface crashes when adding a new item with a ForeignKey

[Ben Gerdemann]

Good morning all,

This problem sure seems like a bug, but it's such a common operation
that I must be doing something wrong. I am using the admin interface
to add a new student to my database. At the same time I also want to
add the parents of the student, so I click on the "+" icon on the
student page to add the data for the parents. The data for the parents
saves fine, but when I click to save the student I always get an error
(copied below). If I do the operation in two steps, adding the parent
first then going to the student page and adding the student linked to
the parents, everything works fine. In fact, if I simply click back
from the error page to the student page I submitted from, click reload
so the parent now appears in the select box, select the parent and
then click save everything works too.

Looking at the traceback, it appears the value of the field for the
ForeignKey in the student that points to the parent has a value of
u"None" when I suppose that it should have an integer value that
points the parent primary key. Anyway, I'm not expert here, but I hope
that someone can help out. This operation seems so common that I must
be doing something wrong.

Cheers,
Ben

Re: Admin interface crashes when adding a new item with a ForeignKey

[Ben Gerdemann]

I figured out the problem. I used inspectdb to import my models from
an existing database. I then marked the primary_key fields with
primary_key=True, but I didn't should have also converted them from
IntegerField to AutoField. Once I did that everything worked fine. I
hope this message saves someone else from debugging in the future. For
future reference the assertion was: "invalid literal for int(): None"

Ben

Intercepting return from new ForeignKey popups? (RelatedObjectLookups.js)

[Ben Gerdemann]

I've been experimenting with an autocomplete widget for ForeignKey
model fields following the very useful advice from Jannis here:
http://jannisleidel.com/2008/11/autocomplete-form-widget-foreignkey-model-fields/
The basic idea is to create a widget with a hidden text field that
contains the ForeignKey ID that is updated by the results of the
autocomplete field.

I've got everything working correctly except for one problem. When
adding a new foreign key by clicking on the "+" the hidden field is
correctly updated with the primary key of the new object, but the
autocomplete field still shows the previous text which is confusing to
the user. The insertion still works correctly of course as it's the
hidden field that is actually used. Any ideas on how to correct this?
It seems the JavaScript code RelatedObjectLookups.js controls this
behavior, but I can't quite get my head around what to do. I need
someway to intercept the return from the Popup to update fields on my
form.

Ben

Frustration with custom Inline forms

[Ben Gerdemann]

I'm trying to customize the inline forms of a model that are displayed
when I'm editing it's parent, but I can't get anything to work! Can
someone help? First, here are my models:

class T22Pais(models.Model):
a22_id = models.AutoField(primary_key=True)
a22_nome_1 = models.CharField("Nome Responsavel
#1",max_length=255)

class T55Visitas(models.Model):
a55_id = models.IntegerField(primary_key=True)
a55_visita_agendada = models.DateTimeField(null=True, blank=True)
a22 = models.ForeignKey(T22Pais,verbose_name="Pais")

The documentation says "The InlineModelAdmin class is a subclass of
ModelAdmin so it inherits all the same functionality as well as some
of its own," so first I tried this:

class T22PaisAdmin(admin.ModelAdmin):
inlines = [T55VisitasInline]

class T55VisitasInline(admin.StackedInline):
exclude = ('a55_id')
model = T55Visitas

but nothing changes. I tried a couple variations of the name without
and without quotes and adding the model hierarchy exclude=
('T55Visitas.a55_id') but nothing worked.

Then I noticed that the documentation refers to form and formset
fields in InlineModelAdmin. The documentation isn't very clear how to
use these, but I tried the following things and nothing had any
effect: the inline form was always rendered with all of its fields:

class T55VisitasInlineForm(forms.ModelForm):
class Meta:
model = T55Visitas
exclude = ('a55_id')

class T55VisitasInline(admin.StackedInline):
model = T55Visitas
form = T55VisitasInlineForm

tried adding a formset:

class T55VisitasInline(admin.StackedInline):
model = T55Visitas
form = T55VisitasInlineForm
formset = inlineformset_factory(
T22Pais,
T55Visitas,
exclude = ('a55_id')
)

adding the same form back into the formset even though I'm already
setting T55VisitasInline.form, but no dice. :(

class T55VisitasInline(admin.StackedInline):
model = T55Visitas
form = T55VisitasInlineForm
formset = inlineformset_factory(
T22Pais,
T55Visitas,
form = T55VisitasInlineForm,
exclude = ('a55_id')
)

How can I get this to work??? Grrr... Ideally, I'd like to have a
fully custom inline form using "fieldsets," but for now I'll settle
for just hiding fields.

Ben

Re: Frustration with custom Inline forms

[Ben Gerdemann]

Ok, so I just noticed that the a55_id field which is the primary key,
was declared as an IntegerField instead of an AutoField which is why
it was showing up on the inline form, but I still can't get any of the
other fields excluded from the inline form so the problem is still
there.

Also, if it helps for understanding Pais = Parents and Visitas =
Visits in Portuguese.

Thanks again for any and all help.

Ben

Re: Frustration with custom Inline forms

[Ben Gerdemann]

Thank you thank you thank you! I knew I was doing something simple
wrong. :)

I've been enjoying my experience using Django so far, but one thing I
have noticed is that the error messages (or in this case lack of error
messages) can be frustrating. It sometimes takes me quite a while to
figure out what caused an exception especially if there are no line
numbers of my own code. In this case, it's actually the Python syntax
and I'm not sure what Django could do if your syntax is wrong, but I
sure spent a while tracking this down....

Re: problem enabling the admin interface

[Ben Eliott]

Sounds like it could be easier to learn by building piecemeal from the  
ground up than working through a dodgy set up.
Keep going to break through the initial stages of getting to grips  
with Django, it'll reward you in the end.

Re: Customising slugify filter

Um, what about a regular python function which replaces '/' with '-'

Implement file upload in admin interface

[Ben Lau]

Hi all,

  I would like to implement a data upload feature in admin interface
for my application. A form with file upload field will be show for a
data model.
The file should be a XML file which is generated by another program
and contain more than one record of data.

  Anybody implemented similar thing before ? Seem that I could
implement it by override ModelAdmin, but it need to modify a lot of
thing.

Thanks.

Re: Implement file upload in admin interface

[Ben Lau]

Hi redbaron,

My approach is to subclass ModelAdmin to implement a import command .
It should need to override the __call__() and create a import_view()
function to handle the import form. Example:

class XXXAdmin(admin.ModelAdmin):



def __call__(self, request, url):

if url == "import":

return self.import_view(request)

else:

return admin.ModelAdmin.__call__(self,request,url)


However, I am still studying how to make the import_view function by
reading the source of ModelAdmin.add_view(). It use quite a lot of
undocumented functions..

Re: dynamic mod wsgi

[Ben Eliott]

Graham,
Thank you for coming back personally to such a lowly wsgi question!  I  
started reading your email and thinking the answer was 'no', then  
ended up thinking 'definitely maybe'. I'll keep an eye out in case you  
post more, otherwise i'll follow those links and your directions and  
hope to report back with some progress.
Thanks and Regards,
Ben

Re: request parsing

[Ben Eliott]

request.FILES
If this is what you mean, I think this is kind of django 101, i'd  
recommend having a solid read through the docs which cover all these  
kind of bases really well.

hmm, don't know. that's the documented approach. you might want to

A Top-Level Django Index for the root URL

[Ben Pritchard]

Hello everyone,

First, a warning: I'm a total noob but I have really enjoyed working
through the tutorial.

The first post-tutorial thing I've done is construct a top-level page
that gets rendered using:

urlpatterns = patterns('',
    (r'^$', 'mysite.views.index'),    

This was necessary because since I've added (r'^polls/',
include('mysite.polls.urls')), the link http://localhost:8000/
failed to render a response (which is understandable).


The intention is that this page will list all my of sandbox projects. 
So at the moment it just links to http://localhost:8000/polls but (a)
coding the link seems like a HTML solution rather than a Django
solution and (b) it will be tedious to update this html template file
each time I add a new subsection to my site.

So, is there a Django solution that can list the available mini-sites
that are available?

I look forward to any help that someone can offer me.

Thanks,
Ben


p.s.: I've searched the mailing list archives but (not surprisingly)
hits for "top-level" "site" "index" "projects" and "list" are producing
rather a lot of hits!!  One candidate I've found is the sites
framework?  Is the answer hidden in there somewhere?

Re: dynamic mod wsgi

[Ben Eliott]

Hi Graham,
I've finally managed to get back to the wildcard subdomains & mod_wsgi  
today. Unfortunately the discussion thread you mentioned has  
disappeared and after a few hours i still seem to be doing a good job  
of getting nowhere.

Although you mentioned using mod_rewrite to get hold of the url  
variable, it looks like the %{SERVER} variable in mod_wsgi might take  
care of this already?

My main issue seems to be to accessing the %{SERVER} (or relevant  
mod_rewrite) variable in the .wsgi script, to specify a particular  
settings file.

Within a VirtualHost i have:
WSGIApplicationGroup %{SERVER}
WSGIDaemonProcess %{SERVER} ...threads etc
WSGIProcessGroup %{SERVER}

So this is probably hoplessly wrong also, but if you can give some  
further pointers that would be most kind.
Thanks and Regards,
Ben

Re: How to set the from a ModelChoiceField?

[Ben Eliott]

I suspect that bots aren't going to follow form submits like this so  
it doesn't matter.
But if you have these GET queries coded into any html  elements,  
thereby becoming part of the sitemap, then it probably will matter.

This is a bit of a common sense punt, i'm not an SEO expert, so  
standing-by to be corrected!

Re: dynamic mod wsgi

[Ben Eliott]

Strange, that thread is down for me. Maybe it has something to do with  
cacheing in a different locale...

Anyhow, the idea is to create a new django instance and point to  
different settings.py files  for different wildcard subdomains.  here  
is current Vhost:


ServerAlias *.stayunstuck.co.uk
RewriteEngine On
RewriteCond %{HTTP_HOST} ^([^.]+)\.stayunstuck\.co\.uk$ [NC]
RewriteRule . - [E=subdomain:%1]

WSGIDaemonProcess test  user=ben group=ben threads=10 processes=1
WSGIProcessGroup %{ENV:subdomain}
WSGIScriptAlias / /home/ben/mod_wsgi/django.wsgi


WSGIApplicationGroup %{ENV:subdomain}
Order deny,allow
Allow from all



The rewrite is assigning the ENV value correctly but  the  
WSGIDaemonProcess has a fixed name. So it  works for a subdomain  
'test', but then fails for anything else.
I'm also not getting how to access the ENV value in the wsgi script to  
specify a different settings file.

Re: dynamic mod wsgi

[Ben Eliott]

I just saw your message below after sending the vhost.

I don't think i'd mind whether it's separate processes or one really  
fat one. I think perhaps separate processes with a quite a short  
inactivity timeout might work quite well? I'd rather keep the overall  
footprint as  small as feasible, especially since i'm only using a  
memory starved VPS for the time being. But this is for alpha-testing  
purposes really so not crucial concern.

I don't know the answer really to your questions, but perhaps if i can  
give you some background:  I'm looking to set up/demonstrate a django  
app for users according to a set of specific settings they choose.  
Subdomains are to identify the client accounts where they can see  
their django app . The subdomain would be temporary for demonstration/ 
set-up purposes and a client account  would get moved across to a  
dedicated domain name in due course.

Based on users entry in a form i can write/re-write python settings,  
and mod_wsgi allows me to programmatically restart a site - this is  
what led me to think it might be possible. The crunch is obviously  
that i want it to create these instances on the fly, so that the user  
completes the form and *bam* their subdomain is there complete with  
their customized django app.

Re: Do sth on time ?

[Ben Eliott]

Maybe look at it from the point of view of whether you need these  
items to actually expire on time, or whether you need them to have  
expired when they're actually accessed from the database.
If the latter you could use a method in your model, + a manager  
function perhaps, to flick the 'expired' switch.
You've probably discounted this already, but it's easy to get stuck in  
a mindset.

Re: Circular imports between managers and models

[Ben Eliott]

Not that pretty/efficient but you could use contenttype contrib  
temporarily.
IF ClassB has a ForeignKey to Class A could you extract the Class A  
model from  a foreign key via Class B's  .meta?
Or the Class B could have a callable method which returned the  
instance of the model you want...
Not sure whether/how these will work but just throwing out some ideas.

Problem with encoding and using ifequal in Django templates

[Ben Gerdemann]

Hello,

I'm having problems using {% ifequal s1 "some text" %} to compare
strings with extended characters in Django templates. When string s1
contains ascii characters >127, I get exceptions in the template
rendering. What am I doing wrong? I'm using UTF-8 coding throughout
the rest of application in both the data, templates and Python code
without any problems. Any ideas?

Cheers,
Ben

views.py

def test(request):
return render_to_response("test.html", {
"s1": "dados",
"s2": "aprovação",
}
  )

test.html

s1={{s1}}
s2={{s2}}

{% ifequal s1 "dados" %}
  s1="dados" is true
{% endifequal %}

{% ifequal s1 "aprovação" %}
  s1="aprovação" is true
{% endifequal %}

{% comment %}
The following two comparions cause the following exception:
Caught an exception while rendering: 'ascii' codec can't decode byte
0xc3 in position 6: ordinal not in range(128)

{% ifequal s2 "dados" %}
  s2="dados" is true
{% endifequal %}

{% ifequal s2 "aprovação" %}
  s2="aprovação" is true
{% endifequal %}
{% endcomment %}

{% ifequal s2 u"dados" %}
  s2="dados" is true
{% endifequal %}

{% comment %}
The following comparison causes the following exception:
Caught an exception while rendering: 'ascii' codec can't encode
characters in position 8-9: ordinal not in range(128)
{% ifequal s2 u"aprovação" %}
  s2="aprovação" is true
{% endifequal %}
{% endcomment %}

Output

s1=dados
s2=aprovação
s1="dados" is true

Sometimes there's nothing like describing a problem to someone else to
help you solve it. :) I should have marked the Python strings as
Unicode like this and everything works now:

def test(request):
return render_to_response("test.html", {
"s1": u"dados",
"s2": u"aprovação",
}
  )

Converting queryset filter() strings to their fields?

[Ben Gerdemann]

Hello,

I think the best why to explain my question is with an example. I have
a model T60CursoAdmin and a query string "a21__a21_ano" that I can use
to search with like this:

T60CursoAdmin.objects.filter(a21__a21_ano=2008)

The models look like this:

class T60Curso(models.Model):
a21 = models.ForeignKey(T21Turma,verbose_name="Turma")
ex = models.CharField()

class T21Turma(models.Model):
a21_ano = models.IntegerField("Ano")

My question is how, can I can get a reference to the 'a21_ano' field
that this filter is referencing? If the filter didn't span through the
foreign key, I could just do:

T60Curso._meta.get_field("ex")

but this doesn't work:

T60Curso._meta.get_field("a21__a21_ano")

Thanks for any and all help.

Cheers,
Bem

signal connection

[Ben Eliott]

Can anyone please suggest why a signal might be failing to connect.  
I'm using 1.0.2 on apache + mod_wsgi. The signal gets picked up fine  
using the localserver, but fails on the server proper.

When i go into the shell and get the signal object and check  
'receivers' i can see the listener registered. But it just doesn't  
seem to want to fire when the event occurs.

The signal is in one app's models.py, when i put a listener in that  
same file it picks it up fine. When i move the listener to a different  
app's models.py this is when it fails.
Something to do with an import conflict? The second app's models.py  
file already imports a class from the signal's models.py file.  Any  
suggestions very welcome, thanks!

Ben

Custom template tags in admin with hacking to source?

[Ben Gerdemann]

Is it possible to add a custom template tag to the admin without
modifying the Django source? I'd like to add a tag to display a
different submit_line, but the only way I can figure out how to do
this is by either adding one of the existing template tags in django/
contrib/admin/templatetags or adding a new file in the directory. I
tried adding a templatetags directory to my app, but it doesn't work
because Django only searches for template tags in the templatetag
directory of the active app. Any ideas about how to do this without
hacking the source?

Cheers,
Ben

Compressed fixtures?

[Ben Davis]

http://docs.djangoproject.com/en/dev/ref/django-admin/#compressed-fixtures

The docs say that you can use compressed fixtures, but I haven't gotten this
to work.  For example, I have myapp/fixtures/myfixture.yaml.gz,  but when I
run ./django-admin.py loaddata myapp/fixtures/myfixture.yaml,  it just exits
with no output, status of 0.

What am I doing wrong?

Re: Compressed fixtures?

[Ben Davis]

Ahh. Searching for "compressed fixtures" on djangoproject.com under the
"1.0" documentation option  reveals the following page:
http://docs.djangoproject.com/en/dev/ref/django-admin/?from=olddocs

That page has the "1.0 Docs" label,  so I'm guessing this is an error in the
documentation?  Is there a place to submit documentation bugs?

I can't decide on a migration framework

[Ben Davis]

I've been looking into both the "South" and "django-evolution" migration
frameworks.   There are things I like about both of them, although I'm
leaning towards django-evolution.

The thing I like about django-evolution is that migrations are described in
the same "language" as your model,  that is,  instead of adding/removing
tables & columns,  we're adding/removing models and fields,  which is (I
believe) the way it should be.  I don't feel like "create_table()" is any
different from SQL's  "CREATE TABLE".

However,  the author of South
claimsto have started the
project out of frustrations with django-evolution.  I've
read those points, and having a really difficult time understanding what
they really mean.  What do they mean by migartions not being "fixed in the
codebase",  and "fixed migrations are all run when an app is first
installed" ?   What exactly are "fixed migrations" anyways?   I'd love to
understand these points as I don't want to regret choosing django-evolution.

I haven't looked into dmigrations that much, but if anyone has any input on
that I'm all ears.

 Thanks!!

Re: I can't decide on a migration framework

are you saying that django-evolution does not support migrating between
"versions"  (ie up and down)?

I'm mostly trying to get an idea of what migration frameworks django
devopers use, and why they prefer it.

Migrations uses the, maybe at some point you needed to add an extra

get back. You would have that list with app and when you install the
app elsewhere you could choose at which point in the migration history
you wanted your database in. Maybe for some testing you needed the
database like it was at some point. Evolution works differently, it
looks at the db and compares it to the models and the try to make the
changes needed when you run syncdb. So in order to controll evolutions
you would need to change to model fields.

Reading data from database tied to another Django project?

[Ben Kreeger]

Here's the situation: I've got two projects, both Django. One is a
simple, public-facing website that renders a library of
reStructuredText files, as well as a couple of simple forms using the
Forms API. The other is a back-end that requires a login from a member
of our staff, and contains database tables, forms, the whole bit; it's
practical purpose is for tracking equipment in buildings across a
college campus.

In this second Django project, let's call it P2, I've got a database
table of all the buildings on our campus, as well as a database table
of all of our equipment, and most pieces of equipment has a barcode
number associated with it.

In the first Django project, let's call it P1, I've got a form where a
patron will fill out information about who they are, what department,
they're with, etc., but I need them to choose a specific building, and
if available, specify the barcode number of the troublesome equipment.
I want to have a dropdown list of all the buildings show up in the
form, but all the data is associated with another project; otherwise,
I'd just do a forms.ModelChoiceForm.

How do I go about accessing that data from P2's database? Do I need to
create a model in P1 and bind it to a certain table in P2's database?
If that's the case, how do I specify access credentials for that
database? Is that in settings.py?

Maybe you want the Django condition decorator, which lets you use HTTP

they're not correct?

Re: Return FK model

[Ben Davis]

It looks you're setting a many-to-many reflexive (circular) relationship
between users.   It seems it would be better to add a ManyToManyField on the
User model, eg:

class User(models.Model):
...
friends = ManyToManyField(User)


Then you could just use "user.friends"

Re: Return FK model

[Ben Davis]

True, you wouldn't be able to modify the auth.User model.   Though you're
wrong about what would happen if you were able to.  What I'm saying is with
a ManyToMany field,  the relationship is with itself (User),  so it would
return User objects.

The django docs suggest using a UserProfile model when you need to add more
information about a user:
http://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users

What you could do is this.  Create a UserProfile model with the friends
reflexive relationship:

  class UserProfile(models.Model):
  user = ForeignKey(User)
  friends = ManyToManyField(UserProfile)


then you could do:

  some_user = UserProfile.objects.get(user=X)
  his_friends = some_user.friends

This would return UserProfile objects, though.  So if you wanted User
objects, you could do

  his_friends = some_user.friends.select_related('user')

This would pull all this user's friends,  plus their information from the
auth_user table in one query,  so while looping through their friends, you
access their user information like so:

   for friend in his_friends:
   this_friends_user_acct = friend.user



Make sense?

Re: Return FK model

[Ben Davis]

@Javier,  not sure.. I've used user profiles on my past sites because that's
what I was told to do a while ago,   if inheritance works with
authentication and the admin,  I would definitely go that route.

Also, @Yanik,  I realized my UserProfile model example above was wrong,
the  user relation should be OneToOneField,   not ForeignKey.

Re: create non-form widgets like a ajax driven table

[Ben Davis]

In django terms,  a table is not a widget.  Widgets are basically different
input methods for form fields.   Django's admin app has a built-in list view
(I think it's called changelist) which you can customize or override.  It
basically just takes some effort to dig into the admin contrib app to see
how it's done.  There may or may not be options on the ModelAdmin that say
whether or not its editable,  but check the docs to be sure.

Django & mod_wsgi, multipart/form-data forms, and hell

[Ben Kreeger]

I've got a model that has an ImageField, and a ModelForm that uses
this model. I've got my template set up using the form fields, and my
form tag is set up with enctype="multipart/form-data" so the picture
upload works.

When I use the included Django development server (runserver command),
I can use this form all day, it uploads photos, all is right with the
world.

When I use my setup with mod_wsgi and Apache2, and I hit submit on
this form while attaching a photo, it just hangs. I've checked my code
(using assert False just to raise an AssertionError) and it doesn't
even make it into my "if request.method == "POST":" statement. It just
sits there. If I don't submit a photo with the form, it's fine.

Before I added the enctype attribute to my form tags, the form would
submit, but if you attached a photo, it wouldn't save.

Anybody seeing this?

Authentication for static files

[Ben Davis]

I would like to be able to serve files that were uploaded via the admin
site;  for example, when someone clicks on the "Currently:" file link in the
changeform.  However, I also have the following requirements:

   1. The file should only be accessible when authenticated via django's
   auth system
   2. Clicking the file link should not present an already authenticated
   user with another authentication challenge

I'm currently using a custom FileSystemStorage location and base_url for
files that should be only accessible via the admin.

I've seen this documentation:
http://docs.djangoproject.com/en/dev/howto/apache-auth/,   but it deals with
mod_python,   and I'm using mod_wsgi,  so I'm not sure if that will work.
Also,  I'm not sure if that solution meets requirement #2.

Any ideas?

Re: Authentication for static files

[Ben Davis]

Actually, I just found out about the X-Sendfile header which I think might
solve this problem.  It basically allows you to set the HttpResponse content
to an empty string,  but the X-Sendfile header tells apache to send a file
from the filesystem,  so apache handles the actual serving of the file, but
it still allows you to do preprocessing beforehand.   I'll probably just
override django.views.static.serve to support this, and use the X-Sendfile
header when in production mode.

Re: can't compare datetime.datetime to datetime.date

[Ben Firshman]

The date() method of the datetime object is what you probably want.  
See the documentation:

http://docs.python.org/lib/datetime-datetime.html

Re: Django in a HA cluster web services application with some near real time elements

[Ben Ford]

Hi there,

I'm probably not qualified to comment on the deeper technical issues
mentioned here. However that said I've just taken over quite a large
codebase that does some of this stuff, and it can be quite painful! I'd
suggest keeping your django code as simple as possible, i.e. just to process
the request and return the results. There are a few instances where we've
called out to other web services in a view and it's gone ok... but there are
a couple where it's bitten us HARD! (SOAP over https using the ZSI library).

If you're thinking of a cron job, then I would say a good match would be a
custom management command, this is the approach we now take as much as
possible and it works well for us.

> It seems likely that parts of our application will want to be
> threaded.  What, if any, issues are there with threading within Django/
> Apache?

I'd second Graham's sentiments here... we're trying to move from fastcgi and
a number of nasty hacks put in place by the previous people to a more normal
setup as per community recommendations for running django at the moment it
isn't easy, we have a lot of bugs surfacing  and a lot of trouble finding
where the originate! Our code uses threadlocal in some places - I'm not sure
how similar threadlocal is to 'threading' (if anyone can enlighten me I'd
appreciate it!), but I think it might be causing a few of our problems.

Cheers,
Ben

Re: Tests in files other than tests.py and models.py

[Ben Ford]

The testrunner is probably the way to go!

I do this:
# somemod.test.py
from somemod import testing as reg # testing is a package with various
modules inside

__test__ = {
'create_tracker': reg.process.create_tracker,
'create_new_user': reg.process.create_new_user,
'default_promo': reg.process.default_promo,
'session_keys': reg.trackers.sess_keys,
}

The modules look like this:

_imports = _pre_setup + r"""
Import what we need
>>> from django.http import HttpRequest
>>> #Other imports here
"""

_pre_setup is a doctest that mimicks the pre_setup method on a django
TestCase and allows me to specify:

_pre_setup = r"""
>>> from django.core.management import call_command
>>> def _pre_setup(*fixtures):
... "see django.test.testcases.TextCase._pre_setup"
... call_command('flush', verbosity=0, interactive=False)
... if fixtures:
... call_command('loaddata', *fixtures, **{'verbosity': 0})
... mail.outbox = []
"""

This way I can mix and match doctests from lots of different places, and I
can use fixtures in my doctests. I find it pretty flexible, but I'm not
really 100% convinced it's the best way to go about this, so I'd be
interested in hearing from others.

Cheers,
Ben

Hell yeah, is it relatively straightforward or very involved? I know python
pretty well, but firefox/komodo extensions are a bit of a black art!

"Eval" in templates?

[Ben Kovitz]

Is there an easy way in Django to do the following?

In blah.html:

   {{ buttonDecidedAtRunTime }} blah blah blah

In the Context passed to blah.html at run-time:

   buttonDecidedAtRunTime: '{% include "button4.html %}'
   thisPage: "/some/path"

   Naturally, the included template might be button1.html,
button2.html, etc., depending on run-time decisions.

In button4.html:

   html  for button #4


The kicker is the {{ thisPage }} inside button4.html.  I'm hoping to
pass thisPage in the context sent to blah.html.  This would make the
code really simple.  Of course, the code you see above will just show
the string literal '{% include "button4.html %}' right in your
browser.

What's needed is something like eval for template tags.  I could
imagine:

   {% eval %}{% buttonDecidedAtRunTime %}{% endeval %}

or maybe even better would be:

   {% eval buttonDecidedAtRunTime %}

Is there a way to do this?  If it's not already in Django, does it
look easy to implement?  I haven't yet implemented a custom tag, but I
read the chapter in the book, and it doesn't look too hard.  On the
other hand, I don't want to spend days mired in it if it's hard.

Or, is there a better way to do what I'm trying to do?  Right now, I
see two other options:  render button4.html and pass the result as the
value of buttonDecidedAtRunTime (this complicates the Python code a
bit, since thisPage must be passed to the subroutine that decides
which button to render); or use {% if %} tags in blah.html (kind of
ugly, involves difficulties with parameter-passing, and we need to do
this all over the place, though we could stuff the {% if %} logic into
an included template).

Re: "Eval" in templates?

[Ben Kovitz]

Thanks for the encouragement, Alex.  This was so easy, it should be a
first lesson in how to write a custom tag.  It took about 15 minutes
and worked the first time!


from django import template

register = template.Library()

@register.tag(name="eval")
def do_eval(parser, token):
   try:
  tagName, variableName = token.split_contents()
   except ValueError:
  raise template.TemplateSyntaxError("%r requires a single
argument: the name of the variable to evaluate as the body of a
template" % tagName)

   return EvalNode(variableName)


class EvalNode(template.Node):

   def __init__(self, variableName):
  self.variableName = variableName


   def render(self, context):
  t = template.Template(context[self.variableName])
  return t.render(context)
