Error in basic template in admin

[Diogo Baeder]

Hi, guys,

I'm having an issue with the basic admin template at my project... 
basically, it says that it doesn't see an "urls" module, in a line that 
tries to include links to the admin documentation, but I've not 
activated the documentation! :-(

Can I post an image here with the traceback screen?

Thanks!

Recursive ManyToMany field question

[Adam Olsen]

I'm trying to make a tagging application.  I want to have tags that
have related tags, ie, if they choose the tag 'car', it should also
choose 'automobile'.  If they choose 'automobile', it should not
automatically choose 'car'.  I'm using something like:

class Tag(models.Model):
   name = models.CharField(max_length=30)
   related = models.ManyToManyField('self')

If I do this:

>>> car = Tag(name='car')
>>> car.save()
>>> automobile = Tag(name='automobile')
>>> automobile.save()
>>> car.related.add(automobile)
>>> car.related.all()
[]
>>> automobile.related.all()
[]

How do I make it so that if I add a relation of 'automobile' to 'car',
it doesn't automatically add a reverse relation like that?

Re: Rendering models using their own templates

[Roberto Cea]

HI Eric,

thanks for the reply.

I sort of found a solution, by poking through the contrib.syndication
app, I added this function to my model:

from django.template import loader

def render(self):
html_tmp = loader.get_template(self.html_template_name)
html = loader.render_to_string(html_tmp.name, {'obj': self})
return html

where self.html_template_name is the path + name of the template, and
it's passed the calling model instance as 'obj'.

Thanks!

Rodrigo

Generic subclass accessor for model inheritance?

[Roberto Cea]

I have a BaseModel and n models that subclass it.
Each instance of the BaseClass has a .name_of_subclass attribute that
returns the subclass instance associated with it.
Is there a generic way of accessing this instance without knowing
beforehand the name of the subclass, something like
base_class_instance.generic_subclass_instance?

Example:

class BaseModel(models.Model):
visible = models.BooleanField(default=True)

class OneSubModel(BaseModel):
   palatable = models.BooleanField(default=True)

class OtherRandomSubModel(BaseModel):
   palatable = models.BooleanField(default=True)

for base_class_instance in BaseModel.objects.filter(visible=True):
print base_class_instance.generic_subclass_instance.palatable()

I'm not sure this will completely solve your problem, but in several  
cases I've added python-only (non-database) attributes to models,  
pointing at a template in my template dirs directory. That way you can  
use generic code to render snippets for a variety of different models.  
You could create a mixin class that provides the render() method,  
using django's template rendering functions and a reference to  
self.component_template, then have models subclass this mixin and  
provide their own component_template attribute.

Hope that's what you were looking for.

Try to create your own filter that compares things (numbers as a case)

In that particular case when you want to check a length of a list, you
can use this:
{% if list|slice:"5:"|length_is:"0" %}
some HTML when the list is short
{% else %}
some HTML when the list is long
{% end if %}

This example tests if list is longer than 5 items or not. Use another
number if you need.

Bests!

Webfaction has small-amount-of-clicks install for Django, and the

It's very Django friendly.

Rendering models using their own templates

[Roberto Cea]

I have a large amount of optional components (with a model for each
one) that will be freely inserted by my users, and it would be
impractical to render each one in a single large template.
I want to give each component a ".render()" method, so I can just call
that from the template.
However, I don't want to have to put together each component's HTML in
its model definition. Ideally, each component would have a
corresponding template file, that would be added together with the
page's other components' output to generate the complete page's HTML.
Is there a way to specify, for each model, a small template-snippet
file that will be used to represent it? Hopefully using Django
standard template syntax?

Best Django host

Hi,

I currently use dreamhost, but the installation process is very slow.
Is it me or this process is overly complicated? All I want is to
install an already written django project but to do that it's like I
have to write the app myself.

I read about dreamhost being not the best, but it's listed at #2 on
django website. Should I use that for my site or buy one of the
packages that features 1-click install, like: http://djangohosting.ch?

I would appreciate if someone can help me out.

It's a test to see if you're paying attention -- you pass :-)

Actually there's a ticket open on this:

http://code.djangoproject.com/ticket/10801

There you can see what it used to be and just use that instead.

Tutorial part 4 doubt

[eric]

Hi

I know it is just an tutorial, but I would like to know how you handle
this issue.

this is the code in 4th tutorial:
{{{
def vote(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
try:
selected_choice = p.choice_set.get(pk=request.POST['choice'])
except (KeyError, Choice.DoesNotExist):
return render_to_response('polls/detail.html', {
'poll': p,
'error_message': "You didn't select a choice.",
})
else:
selected_choice.votes += 1
selected_choice.save()
return HttpResponseRedirect(reverse
('mysite.polls.views.results', args=(p.id,)))
}}}

On except you render the same template as the "detail" function to
show the error message, but at r'^(?P\d+)/vote/$' url. If you
send the form from that url, it will post the form at r'^(?P\d
+)/vote/vote/$'.

How to solve that?

I hope I was clear.

thanks in advance

Eric

Re: can't create django project

[MFA]

I'm a rook too and received the same error.

I re-read the installation instructions here:
http://docs.djangoproject.com/en/dev/topics/install/#installing-official-release

It turns out I had to run "python setup.py install".   I believe this
copies the django-admin.py to a location, or places a path variable,
so it is accessible.
Once i ran the command above, i was able to successfully use "django-
admin.py startproject X"

good luck.

Re: user object in login.html

[Jon]

Ah, and if you only want to display a message on the login page,
that's possible too. In that case you don't use the redirect in the
view, but use an if clause in your index.html template.

Something like this:

{% if logged_in %}
  You are logged in already.
{% endif %}

Re: user object in login.html

[Jon]

Simply have an 'if logged in:' clause at the beginning of your login
view definition that redirects to the /loggedin/ view if it matches.

Of course this implies that you know some variable that will always
match once someone is logged in.

Most likely, django sets this already. If you cannot find one, you
just set one yourself.

I am new to django, only started learning it last week, so the
solution may look a bit dirty in the eyes of seasoned django
developers, but i am sure it will work.

Have a look at the forms chapter, and read about the
HttpResponseRedirect to see how to go about doing the redirect.

What version of Django are you running?  Ordering fields is only supported

can't create django project

Hi,

  However, I got the message sais:  'django-admin.py' is not
recognized as an internal or external command, operable program or

problem.   I also got (1, 0, 2, 'final', 0) from typing

Can anyone tell me how to fix the django-admin.py problem?  Thanks.

Creating a custom form from models, problems when ordering

[ccsakuweb]

I have a form from a model. I add 3 new inputs. Then when I write in
Meta :
model = models.Table
fields = ['attribute2', 'newInput1', 'newInput2', 'newInput3',
'attribute3']
for example, the final order is not respect the new inputs. Only
respect the attributes of the model in the fields array.
The result in the form is:
attribute2
attribute3
newInput1
newInput2
newInput3

Is there any solution to order the new inputs too? Or the solution is
only to create a form without inheritance from a model?

I hope you understand me. Sorry because my simple english.

Re: Installing django

[Aneesh]

What operating system are you using?  If it's unix, Linux, or Mac OS
X, there should be a file named ".bash_profile" in your home directory
(if you're using bash).  You can run the export statements directly
from a shell prompt on any of these OS-es.  You should also put the
export statements in the .bash_profile (anywhere in that file is file)

Re: ForeignKeyRawId widget contains incorrect link when you click on search gif?

[Margie]

When I do that I just get '1.1 beta 1' (no svn revision info).
However, I can see that I am in my newly installed library by putting
pdb.set_trace() into the code.


I checked it out like this:
  svn co http://code.djangoproject.com/svn/django/trunk/
django_trunk_05_18

At the end it printed:
  Checked out revision 10821.

I installed it with this command:

python setup.py install --prefix /home/mlevine/django/django_libs/
django_trunk_05_18

Then in settings.py and manage.py I insert "/home/mlevine/django/
django_libs/django_trunk_05_18/lib/python2.5/site-packages" at the
front of sys.path.

Does the installation make it so that it doesn't print the svn
revision info?

I'd expect an AttributeError is you are accessing an attribute that
doesn't exist. Thus my assumption.

Re: ForeignKeyRawId widget contains incorrect link when you click on search gif?

[Margie]

I tried it on trunk (checked out yesterday) and I see the problem
there as well.  Note, this is in the change list view.  The problem
doesn't appear in the edit forf view.  Here's my testcase:

### urls.py 

from django.conf.urls.defaults import *
from django.conf import settings

from django.contrib import admin
admin.autodiscover()

import os

urlpatterns = patterns('',
   (r'^admin/', include(admin.site.urls)),
)


if settings.SERVE_MEDIA:
urlpatterns += patterns('',
(r'^site_media/(?P.*)$', 'django.views.static.serve',
{'document_root': os.path.join(os.path.dirname(__file__),
"site_media")}),
)

### models.py 
from django.db import models

class Task(models.Model):
name=models.CharField(max_length=50, blank=True, null=True)
owner = models.ForeignKey('auth.User', blank=True, null=True,
related_name="tasks")

### admin.py #
from django.contrib import admin

Re: User attribute access from within profile model

There are attributes for first_name and last_name, why wouldn't

Re: MultiValueField with required=True problem

At least in 1.0.x, MultiValueField.clean will throw a validation error
if self.required is True and one of that values in the value array is
empty. I'm looking at django/forms/fields.py:800 :

if self.required and field_value in EMPTY_VALUES:
raise ValidationError(self.error_messages['required'])

I don't understand why this should be the case, but if I'm reading
correctly then you are reporting correctly as well :). Hope that
helps.

Also, your embed code is trying load several things (flash file, MP3
file) from a "file:///" url.  Your browser might have a problem with
this (cross domain restrictions).  I'd try serving all of your static
resources through django (of course you'll want to use something else
for static media when if you put this into production).

You're talking about being a client of web services rather than a  
server so it's often as simple as just querying the relevant web  
service from your views.py file. Using Amazon as an example:

http://code.djangoproject.com/wiki/WebServices

http://pyaws.sourceforge.net/

The quick start in that second link shows how simple it could be. Just  
use that example in views.py and pass the info to your template. Then  
since you're going to be making queries to a service that, depending  
on your network, may or may be available or may be slow, take a look  
at caching that information.

Installing django

[LeonTheCleaner]

Hi,

I am trying to install django by using this:

http://wiki.dreamhost.com/Django

but there are a few things I don't understand.

1. Where am I supposed to run stuff like these:

export PATH=$PATH:$HOME/django_src/django/bin
export PYTHONPATH=$PYTHONPATH:$HOME/django_src:$HOME/django_projects

2. Also where is the .base_profile? Am I supposed to locate it
manually?




Thanks in advance.

Form Help

[eric.frederich]

I need a view to edit Enrollment objects for a particular Offering.

An Offering has a foreign key to a Room and a Course.  All three of
these (Offering, Room, and Course) have a maximum capacity field which
can be null (for unlimited).  Offering has a method called
get_max_capacity() which returns the minimum of all 3 maximums or None
if none have them defined.

An Enrollment has a foreign key to User and Offering.

I need a per-offering view of enrollments.  Where the number of forms
is the maximum capacity of the Offering or 3 extra if not defined.  I
would like to edit all fields (except for the foreign key to Offering
since this view is offering specific).

I am having the following problems trying to make the view Offering
specific.

1) Trying to use exclude=('offering',) since all Enrollments in this
view should be for the given offering.

2) Trying to make the view offering specific by using
queryset=offering.enrollment_set.all().

Without 1) or 2) I am able to edit existing Enrollments.  I am able to
create new Enrollments using the empty forms.

When I have exclude=('offering',) I cannot make use of the extra forms
because it will complain about no offering_id being set.

When I use queryset=offering.enrollment_set.all() and I submit, it
complains about all the empty forms not having information in them.

What am I doing wrong?

Here is my template and view code


{% extends "train/base_admin.html" %}
{% block content %}
Enrollments for {{ offering }}

{{ formset.management_form }}
{% for form in formset.forms %}

{{ form }}


{% endfor %}


{% endblock %}


@login_required
def offering_admin(request, location_slug, offering_id):

offering = get_object_or_404(Offering, id=offering_id)

location = get_object_or_404(Location, slug=location_slug)

# We use location in this view just so that urls look similar
# we could get location from offering's room.  Still... make sure
# the url is okay.
if offering.room.location != location:
return showmessage(request, 'Bad url.  Offering / Location
missmatch')

if not request.user.profile.gid in settings.TRAIN_ADMINS
[location.name]:
return showmessage(request, 'You are not an admin for location
%s' % location.long_name)

try:
extra = int(request.REQUEST.get('extra'))
except:
if offering.get_max_capacity():
extra = offering.get_max_capacity() -
offering.enrollment_set.count()
else:
extra = 3

EnrollmentFormSet = modelformset_factory(Enrollment, extra=extra,
exclude=('offering',))

if request.method == 'POST':
formset = EnrollmentFormSet(request.POST, request.FILES)
if formset.is_valid():
print 'VALID!!!'
# do something with the formset.cleaned_data
formset.save()
# calling save may have populated variables (like cost
center when left blank)
# so get it again from the database rather than the
request
#formset = EnrollmentFormSet
(queryset=offering.enrollment_set.all())
else:
#formset = EnrollmentFormSet
(queryset=offering.enrollment_set.all())
formset = EnrollmentFormSet()

return render_to_response(
'train/offering_admin_form.html',
{'offering': offering,
 'formset' : formset,},
context_instance=RequestContext(request)
)

Re: Question: What's the best way to denormalize M2M data?

[Ben Welsh]

I'm imagining some pretty simple that would capture the M2M
relationship, like this slightly modified one from the Django docs

models:
http://www.djangoproject.com/documentation/models/many_to_many/

picklefield:
http://www.djangosnippets.org/snippets/513/

from django.db import models
from utils.fields import PickleField

class Publication(models.Model):
title = models.CharField(max_length=30)

def __unicode__(self):
return self.title

class Meta:
ordering = ('title',)

class Article(models.Model):
headline = models.CharField(max_length=100)
publications = models.ManyToManyField(Publication)
publications_denorm = PickleField(null=True, editable=False)

def __unicode__(self):
return self.headline

class Meta:
ordering = ('headline',)

def save(self):
  print "Before", self.publications.all()
  super(Article, self).save()
  print "after", self.publications.all()


But my efforts to pull things like this off have been frustrated by being
unable to be a signals to do the necessary filling in of the _denorm field.
As described here:
http://groups.google.com/group/django-users/browse_thread/thread/99680b69d2d4799c/07093d3695163269

But, to reiterate my first post, this is just one hacky concept that I've
stumbled with. I suspect there might be better concepts back at the drawing
board and wouldn't want to push it as a best practice.

RE: Dynamic ForeignKey using or how ?

[Will Matos]

You can use model inheritance

class SomeCommonNameHere(models.Model):
title = models.CharField(max_length=100)
body = models.TextField()

class Casts(SomeCommonNameHere):
somecastfield = models

class Articles(SomeCommonNameHere):
somearticlefield = models...

class Faves(models.Model):
post = models.ForeignKey(SomeCommonNameHere)
user = models.ForeignKey(User,unique=True)

you can then access the subclass' specific fields by referencing:
#where fave is an instance of Faves...  
fave.post.articles.somearticlefield...
 or
fave.post.casts.somecastfield...



You may also want to look at proxy classes.

http://127.0.0.1:8000/admin/admin/logout/ (duplicate admin)

[Jesse]

I'm setting up a new server with Apache/mod_python on windows.  I can
see my data on the admin page, but when I log out it is logging out
with two admin/admin and I get an error page not found.  I cannot
figure out why this is happening?
Thx

Admin formating for inline, fieldsets don't work?

[Keith Pettit]

In the admin pages I'm using a parent that can have multiple child objects.
For display I'm using inlines in my admin.py.   The parent displays fine and
the child displays fine using inlines but I can't seem to find out a way to
control the formating of the inline child objects.

This is a example of the admin.py I have.  Ticket being the parent, and load
being the child.

from ticket.models import Load, Ticket

class LoadsInline(admin.TabularInline):
  model = Load

class TicketAdmin(admin.ModelAdmin):
  inlines = [LoadsInline,]
  list_display = ('id', 'type', 'unload_date', 'transporter', 'shipper',
'receiver')

admin.site.register(Ticket, TicketAdmin)
admin.site.register(Load)


I've tried various fieldset options but for the child inline "Load" it
dosen't seem to matter if I but the fieldsets under Ticket or Load, the
admin site dosen't pay attention to the formating I set.

So long story short, how can do something simlar to the fieldsets option
with inlines?

Thanks

Perhaps I've fumbled my way past the obvious, but the problem I'm running

Hi Russ,
never thought of this...

But...
If we have a relation between Alice and Bob, we could save just one
relationship with the intermediate data, and when we access the
symmetrical m2m field, we could use an UNION to retrieve relations
from both Alice and Bob.

For example in this situation:

class Person(models.Model):
   friends = models.ManyToManyField("self", through="Friendship")

class Friendship(models.Model):
  person_a = models.ForeignKey(Person)
  person_b = models.ForeignKey(Person, related_name="_unused_")

and  p is a  Person with some friends, accessing p.friends could
result in something like:

SELECT DISTINCT person_a as friend_id FROM friendship WHERE person_b = p.pk
UNION
SELECT DISTINCT person_b as friend_Id FROM friendship WHERE person_a = p.pk

Probably this could be done without the UNION using an OR, but I'm no
sql guru :(

I think this is crucial to represent the typical "friendship" model,
infact Pinax is currently using some workarounds to overcome this
limitation.

What  do you think?

Re: Separate User namespace

[Aneesh]

How many private users do you have?  If it's just a small number,
consider using the same model for all Users, and making some profiles
public/private.  A couple usernames will be taken, but that shouldn't
be a big deal.

If you actually want a second namespace, I'm not sure of the best way
to proceed.

I'd guess because you made it a simple IntegerField rather than an
AutoField.  If you want it to be automatically assigned and incremented you
need to make it an AutoField:

Re: Parsing the arguments in HTTP GET

I've used the forms framework with GET (I'm using it for a search form
and a 'q' parameter), but it never occurred to me to use it to
validate non-form parameters.

Oracle and Primary Keys

[Tim Sawyer]

Hi,

I have a django model that looks like this:

class Lender(models.Model):
id = models.IntegerField(primary_key=True, db_column='lse_serial')
version = models.IntegerField(db_column='lse_version')
name = models.CharField(max_length=50, db_column='lse_lender')
uri = models.TextField(db_column='lse_lender_uri')

def __unicode__(self):
return self.name

class Meta:
ordering = ['name']
db_table = 'lender_service_endpoints'

I'm connecting to an Oracle database.  If I do a 

python manage.py sqlall home

I get the following SQL:

CREATE TABLE "LENDER_SERVICE_ENDPOINTS" (
"LSE_SERIAL" NUMBER(11) NOT NULL PRIMARY KEY,
"LSE_VERSION" NUMBER(11) NOT NULL,
"LSE_LENDER" NVARCHAR2(50) NULL,
"LSE_LENDER_URI" NCLOB NULL
)
;
COMMIT;

It hasn't created a sequence/trigger for the primary key.  Why is this?  It 
does work for tables that have an implicit primary key (ie not specified in the 
model.)

I'm using django 1.0.2.

Cheers,

Tim.

You mean, something like the Forms framework? :-)

Ordinarily, the Forms framework is used to handle inputs submitted
using HTML  elements via a HTTP POST, but the Forms framework
will work just as well with request.GET. Your Form definition can
declare the get arguments that will be accepted, perform validation on
them if required, specify default values, specify required arguments,
and cross validate between optional arguments (i.e., if you specify x,
you must specify y, but you can't specify z as well).

The fact that you will never use the rendering portion of the Form
doesn't matter at all - you just use the validation part that you
require.

Replying to myself, here is the solution:



class LimitedCustomUserAdmin(UserAdmin):
 inlines = [ProfileAdmin]
 form = forms.CustomUserChangeForm
 fieldsets = (
 (None, {'fields': ('username', 'password')}),
 ('Personal info', {'fields': ('first_name', 'last_name', 
'email')}),
 ('Permissions', {'fields': ('is_staff', 'is_active', 
'is_superuser')}),
 ('Important dates', {'fields': ('last_login', 'date_joined')}),
 ('Groups', {'fields': ('groups',)}),
 )



class CustomUserAdmin(LimitedCustomUserAdmin):
 fieldsets = (
 (None, {'fields': ('username', 'password')}),
 ('Personal info', {'fields': ('first_name', 'last_name', 
'email')}),
 ('Permissions', {'fields': ('is_staff', 'is_active', 
'is_superuser', 'user_permissions')}),
 ('Important dates', {'fields': ('last_login', 'date_joined')}),
 ('Groups', {'fields': ('groups',)}),
 )
 def __init__(self,*args,**kwargs):
 CustomUserAdmin.limited_user_admin = 
LimitedCustomUserAdmin(*args,**kwargs)
 return super(CustomUserAdmin,self).__init__(*args,**kwargs)

 def __call__(self, *args, **kwargs):
 if get_current_user().is_superuser:
 return super(CustomUserAdmin, self).__call__(*args, **kwargs)
 else:
 return CustomUserAdmin.limited_user_admin(*args,**kwargs)



This way, super_users can view/edit the fields defined in 
CustomUserAdmin and non super_users can view/edit the fields on 
LimitedCustomUserAdmin.


Note: You've to register only CustomUserAdmin with the User model.

Re: Parsing the arguments in HTTP GET

This is the only real way to do this with Django, though I do wish
there was a core Django way to validate GET params, ie which ones are

RE: Need help for nested list in template

[Will Matos]

In this case a dictionary would not be necessary if he is indeed adding
the model object itself:

It appears he is appending the UserStatus instance.

Build a dict instead, where you wish to refer to specific elements.

Eg:

foo = [ { 'id': 20, 'name': sdfs, }, { . } ]

and 

{% for item in foo %}
{{ item.name }}
{% endfor %}

RE: Parsing the arguments in HTTP GET

[Will Matos]

You wouldn't match this using a url pattern.  The rest of the query
string will be in the request.GET list.  So you can do the following:

ui=request.GET['ui']
shva=request.GET['shva']
name=request.GET['name']

you'll probably want to check that it exists first by doing:
  if 'ui' in request.GET:
ui=request.GET['ui']

or you can default it by doing:
  ui=request.GET.get('ui','defaultvalue')

I am very new to django. I am following along the tutorial. But I want

Need help for nested list in template

[laspal]

Hi,
My model is :
   id  val msg
   20 1234 text
   20 1245text
   20 1275  text
   20 1356  text

so I have to display record in calendar format.
I am doing it in this way:
final_list =[]
somelist = [1200, 1250, 1300, 1350, 1400]
val = 0
i = iter(range(5))
testing_list =[]
for item in i:
user_status_list = UserStatus.objects.filter(id =20,time__gte
= somelist[val], time__lte = somelist[val+1))
  for item in user_status_list:
   testing_list.append(item)

final_list.append(testing_list)

so my final list should look like:

[ [  [20, 1234, sdfs], [20, 1245, sdffd]  ],  [ 20,1275, dfdfgf], [ ],
[20, 1356, dsfdf] ]

wanted to know How can I use this list in my template.
for item in final_list:
 for val in item:
print val.id, val.val, val.msg

which is wrong.
how can I fix this.

thanks...

It was likely posted 3 times because it was being held for moderation (new
members posts are moderated so as to limit spam on the list), so it seemed
to the poster that  the post didn't go through.  When I see absolutely
identical posts I generally remove all but one, but if there are differences
I let them all through since I don't want to try to sort out which one
contains the most information.   As there were slight differences here I
sent them all through.  So, partly my fault.

We could make the new poster moderation fact more obvious by noting it in
the welcome message but from my experience in using that message on
django-developers to guide people to the right list it will have limited
effect.  People don't read it.  So, best to just try to ignore what look
like repeated questions by newcomers.  It's better than having the list
overrun with spam.

The template (or at least the part that includes the form definition) you
use for the form would have been helpful to post, as  that would have shown
whether you had the enctype="multipart/form-data" mentioned by Thomas.

The other part you haven't shown is how you create the form from the post
data in the view.  My guess would be you are not passing request.FILES in
when you instantiate the form.  See:

http://docs.djangoproject.com/en/dev/topics/http/file-uploads/

There was a bug similar to this when using raw_id from the change_list view
with list_editable, however this was resolved (after the beta though I
think).

I can't recreate this with either the alpha or current trunk level (don't
have beta set up to test easily at the moment).  I tried both the 1.0 style

This is a sort of solution: A ChoiceField is populated at render time
by data either called from the ModelForm relationship or from a
ModelChoiceField lookup, and populates the HTML select field on the
form. It is this instance that is validated. Populating the choices
dictionary therefore deletes the data from the lookup:

class ProductForm(ModelForm):
  prodsubcat = forms.ModelChoiceField(ProductSubCategory.objects,
widget=forms.Select(attrs={'disabled': 'true'}), choices =(('-1',
'Select Top Category'),))

and breaks the validation.

If the field is rendered without the choices dictionary, but with the
'disabled' attribute, it will display as a disabled select field.
Selecting an option from the prodtopcat select field calls the Ajax
lookup, which populates the prodsubcat field with filtered data in the
browser, but not in the field object. Selecting a category from the
prodsubcat field returns an option

Posting a bunch of badly-formatted SQL is not at all helpful. What do
you actually want to achieve? If you can spell it out in plain
language - ie 'I want all the users where...' - then it might be more
obvious how to do it in Django.

You might want to use "generic relations" for this. They are described in
the contenttypes framework.

Hope this helps a bit,

preferred/correct way to modify imagefields

[ozgurisil]

Hello all,

I have spent considerable time going through the documentation but
have been unable to find clear information about how to save an image
after uploading it via a form. I think I have somehow missed it. After
trial and error, I have done it in this way:

content = request.FILES['image']
foo.img.save(filepath, content=content,save=False)

here foo is an instance of the Foo model, which has an ImageField
named img

Is this the recommended way to upload an image (for forms that are not
modelform)?

And I update an imagefield (ie, set it to point another file) by
setting it to its relative path against the path defined in the
MEDIA_ROOT constant. I wonder if this is also correct.

A third question is that when I use the default option for the
ImageField, the field is set to an absolute path (MEDIA_ROOT +
mypath), and this stems problems such as foo.img.url() giving a path
instead of a url. How can I prevent that?

Thanks for your help in advance.

Re: crossdomain.xml

[Matt Davies]

Thanks James
I'm serving the sites with nginx, but in my django urls file I'm using this
line for a simple pages app we've built.

urlpatterns += patterns('fact.pages.views',
(r'^(?P.*)$', 'page'),
)

What happens is that whatever you put into the URL the pages app will try
and serve it.

So what you are saying is that I should be able to tell nginx to serve up
the file prior to handing off the request to django, is that about it?

It should be easy, nes't pas?

You can set up some sort of override to tell your web server -- not
Django -- to just serve up the file. Examples are available here:

Re: models unique_for_date

[Reiner]

Hey,

most of the options on a ModelAdmin control the display of your model,
and how you interact with it, in the admin site. What fields you want
to show in the table (list_display), how many objects per page
(list_per_page) and so on:

ModelAdmin options: 
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-options

Whereas fields options in your Model let you further define your
model's specification. You already define what fields your model
consists of, and with unique_for_date you add another constraint to
your model field. It may be enforced on the admin form level, but I
think the only reason for this is, that enforcing it on the database
level is actually not possible, or not reasonable - and maybe it will
be enforced on the database level some day.

Field options on models: 
http://docs.djangoproject.com/en/dev/ref/models/fields/#field-options

So think of the ModelAdmin options as a mean to control (mostly)
display and interaction with the model, and field options as further
constraints to your model. You want your model specification to be in
only one place, and that would be in the model itself.

Regards,
Reiner

Your PYTHONPATH is probably not set correctly. You'll have to make sure 
the environment variable is set properly for the IIS user. There are 
couple special users if I remember correctly.

I'm not sure if you can set an ISAPI filter to run as a specific user, 
if so, that could be another route.

Just override otherClass's widget.

crossdomain.xml

[Matt Davies]

Morning everyone
Stupid question number 243

I've been asked to server up a crossdomain.xml file at the root of our web
sites so that another team of developers can access our data via Flash.

How do I set that up in the urls.py file?  I use one urls.py file for many
web sites so it would be far easier to put it in here.

I've got to this bit but can't think how I can tell the app to serve the doc
from the root folder

urlpatterns = patterns('',
(r'^crossdomain.xml', What goes in here?)
)

We're using a really old version of django for these sites, I think it's
revision 5643, foof, old as.

Any help, greatly appreciated.
