LOL, Makes perfect sense and trivial to fix.

I have a few versions running (963, 1.0 and trunk) and obviously
messed up somewhere.

Thanks!

QuerySet extra() duplicate table

[Rares Vernica]

Hello,

I am using QuerySet "extra()" function. For the "tables" parameter I
need to specify the same table multiple times, so I included an alias
for each table. Unfortunately Django quotes the table names and
everything is messed up.

The "tables" parameter for the "extra()" is:

  tables ['FName F0', 'FName_Person Fp0', 'FName F1', 'FName_Person Fp1']

Here is how the generated query looks like:

  SELECT COUNT(DISTINCT `Person`.`id`)
  FROM
`Person` ,
`FName F0` ,
`FName_Person Fp0` ,
`FName F1` , 
`FName_Person Fp1` 
  WHERE ...

If I remove the alias, Django does not realize that I give the same
table multiple times and does not generate any aliases.

I really need the same table multiple times.

Is there a way around this?

An easy fix might be to ask Django not to quote the "tables"
parameter. Is there a easy way to do this?

Thanks.

I can't tell what's going on, but you have a whole lot of extraneous  
and redundant imports in your views module, including importing  
auth.models.User where you don't need it; try cleaning up your imports  
first. Importing auth and then in the next line doing 'from auth  
import x y z' is only going to make debugging harder.

Another thing to note, though I don't know quite what it means, is  
that the error message "No module named User" indicates that something  
is doing "import User" rather than "from  import User".  
That could help track down the problem.

Re: Custom template tag problem: "No module named models"

[Chris Amico]

I think it's fixed now. After much refreshing (I'm editing in Coda) a
bookmarks.pyc file appeared. Once that was gone, the tag library did
load correctly. I have a different error coming up now, which I'll try
to fix or post separately if I can't.

Thanks for the help and patience, folks.

Depending on what you're expecting to store, and how you're expecting  
to use it, you can also pickle python objects and store them in the  
database. From your example, it looks like you could associate a  
dictionary of metadata with each model instance, pickle that  
dictionary, and store the result in the database field. One more  
option...

Re: Getting lists/dictionaries out of the database

[Ned Batchelder]

If you are going to use eval, and the data comes from somewhere else, 
you should try safe_eval (http://code.activestate.com/recipes/364469/) 
as a way to get the convenience of unpacking Python literals, but 
without the danger of full evaluation. 

If a malicious user could get data into that field, he could add 
"[os.system('rm -rf /etc')]" to it, and a full eval would cause havoc, 
for example.

cheeserater css reference

[coderb]

hi all,

I'm learning django using a downloaded copy of cheeserater  (thanks
Jacob)

but am stuck at an early hurdle.

The template base.html has the following css references:
http://media.jacobian.org/cheeserater/
reset.css" type="text/css">
http://media.jacobian.org/cheeserater/
cheeserater.css" type="text/css">

I'm trying to change this template to reference the dowloaded project
css files located in
cheeserater/media/

my attempts by changing the settings.py  MEDIA_ROOT  and MEDIA_URL
values have all failed.

I know django docs mentions using media as a static class definition,
but thats not the way cheeserater is defined (I think), so if anyone
give me a quick pointer here, I'd really appreciate it.

thanks

the models.py is where it comes from, if you are talking about view.py
these are the two entries that I thought should have taken care of
it.  The error that that it was looking for class name User,like the
one that is the auth.models, but from my view.py.  If I am read it
right.

from django.contrib.auth.models import User
from intranet.timesheets.models import user, worked, fedtime

Is Django case sensitive?  Is user and User the same thing?

class time(models.Model):

user = models.CharField(max_length=20, blank=True)

fedtime = models.IntegerField(null=True, blank=True)

date = models.DateField(null=True, blank=True)

worked = models.CharField(max_length=3, blank=True)
year = models.IntegerField(null=True, blank=True)

month = models.IntegerField(null=True, blank=True)
day = models.IntegerField(null=True, blank=True)
#t=time(user=user, fedtime=fedtime, date=date, worked=worked)
#times.objects
#
#t.obejects
#all_times= times.objects.all()
class Meta:

db_table = u'timesheet'

There might be a Python networking library out there, or you could parse
the output of "ifconfig" on linux, or "ipconfig" on windows.
You could look at the SERVER_NAME environmental variable, which is
usually the server's fqdn, which is as good as the IP address.

If so you need to import that at the top of your models.py file

Get External IP Address

[Ty]

I'd like to grab the users external IP address. I'm using it for a
spam catching class that I'm porting over to Django/Python. Is this
possible?

This person outlines how to 'hack' it, but I'd rather not depend on an
external site.

Json Serialization / Form Validation error

[[EMAIL PROTECTED]]

Hello,

I'm having a hard time understanding why Django won't let me serialize
a dictionary of form errors. Can anyone explain why Django throws an
error if I try to serialize someform.errors, even if I copy it into a
plain dictionary?

#!/usr/bin/env python
from django.utils import simplejson
from project.main.models import SampleForm

test = {}
simplejson.dumps(test) # works

test = {'key': [u"value"]}
simplejson.dumps(test) # works

# suppose SampleForms wants a text and url field
# I just give it a text field to test
form = SampleForm({"text": "sample text"})
d = {} # make a new dictionary
# update d so we're working with a plain dictionary
d.update(f.errors)
type(d) # returns dict

# fails: 
# is not JSON serializable
simplejson.dumps(d)

Specify the post_save_redirect as a callable instead of an object in the
extra_context dictionary:

def reverse_home():
return reverse('project-home')

urlpatterns = patterns('',
   url(r'^$', list_detail.object_list,
   {'queryset': Project.objects.all()}, 'project-home'),
   url(r'^new$', create_update.create_object,
   {'model': Project, 'post_save_redirect': reverse_home},
'project-new'),
)

Re: Getting lists/dictionaries out of the database

[timc3]

Thanks for the help. Yeah, my terminology is quite often wrong, to
much context switching with other things.

Unfortunately I am never sure what will go in to that field, just data
that's sourced from various types of media, and populated from another
system. I do know that it will almost always probably be in that
format though.

So I am going to try your method, I have thought to fix it properly I
should use a datatype within PostgreSQL that supports what I am trying
to do, but alas Django doesn't support it and neither does the other
application.

What's a good way to have an integrated blog for my django site with the same user login for blog comments?

[MikeN]

I want to create an integrated blog for my Django powered site.  I
want it to be integrated with my site in the following ways:
1) I want to be able to use my base django template to frame the outer
portion of all the displayed blog content
--> I want to be able to put the entire contents of the blog in a
block from my base site.
2) I want the blog to use the auth user logins from my site for blog
comments
3) I want all of the data in the blog to be in a separate database
from my sites application so that no vulnerability in the blog code
would lead to my site being compromised.

I realize 2 and 3 might conflict with each other since at least the
user table would have to be shared, unless each database (my
application's database and the blog's database) has a duplicate copy
of the user table.

I was looking to try and achieve this integration with Wordpress, has
anyone had luck with a similar usage of wordpress in a django powered
site?  Would one of the django based blog applications be better for
this kind of integration?

Certainly.  Here's the doc on what you can put in list_display:

http://docs.djangoproject.com/en/dev/ref/contrib/admin/#list-display

If the __unicode__ method of the Post model displays its name, then you
simply add the name of the ForeignKey field for Post in Comment and you'll
get what you were looking for by trying 'Post.name'.  If Post's __unicode__
method isn't what you want to see, write a method on the CommentAdmin model
that returns what you want to see and include it in list_display.

You've apparently layered a recent version of Django on top of an older one
without first deleting the older one.  This file
'django/contrib/admin/templates/admin_doc/model_detail.html' no longer
exists in the source tree, it has been moved to under
'django/contrib/admindoc/templates'.  The version you have is from sometime
before autoescape was implemented, but the code that is running is from
after.  If I were you I would delete everything under
'/Library/Python/2.5/site-packages/django/' and reinstall from scratch
because if you have this file left over you may have more, and they will
only lead to confusing errors.

ensuring a string does not get escaped in views.py

[Kevin]

All,

I am new to Python and Django. I'm quickly catching on but have
finally run in to my first issue.

I'm building a simple app that will work with Google's Picasa. The
idea is to copy an album from one account to another, something that
Picasa won't let you do in its interface.

Here's the thing--I have this working within the Python shell, but
can't make it work with Django.

To retrieve an Album from Picasa, the code looks something like this:
album_uri_to_copy = request.POST['album_uri']
gclient1 = gdata.photos.service.PhotosService()
gclient1.ClientLogin( guser1, gpassword1 )
album_feed = gclient1.GetFeed(album_uri_to_copy)

And album_uri_to_copy might look like:
http://www.ggpht.com//data/feed/api/user/someuser/album?id=4rdioE_s=photo

When calling:
album_feed = gclient1.GetFeed(album_uri_to_copy)

from a Python shell it works fine. When calling it from Django it
returns an Exception saying that album_uri_to_copy isn't a valid uri
or atom feed (this is a google error message).

I SUSPECT that the & is getting changed to "". The thing is, I've
used {{ album_uri|safe }} in my template, so album_uri_to_copy should
be safe! I'm thinking that Django is interfering with the
album_uri_to_copy string in the GetFeed() call.

Can anyone give me some troubleshooting options?

Thanks!

Re: Admin won't display datetime widget with custom form?

[mthorley]

Oh I see. I thought that a DateTimeField had a split date widget by
default. Now I see that it does not. I was rendering as a input field
because that IS the default widget for a DateTimeField.

Thanks for that last clarification, that dispelled all confusion.

Re: Named URL Patterns

[dkadish]

Okay. I think the issue is that I am trying to use reverse( ) in the
URLConf file. According to the django docs, "the reverse() function
has to import all of your URLConf files and examine the name of each
view". My thinking is that this is leading to to attempt to import
itself as it evaluates the URL.

Can anyone confirm this? Is there a known workaround?

Cheers,

David

I've tried something like this but I can't get anything working:
list_display = ('Post.name', 'name', 'email', 'website', 'date',
'approved', 'is_admin',)

Is this currently possible?

page not updating right away

[ashbii]

I am new to Django, but love it so far.  I went through a tutorial and
created a basic blog app.  I'm using Django's admin interface to add
new blog posts -- I have a blog "Post" model.

My problem is that whenever I enter and save a new blog post via
admin, its not showing up on the web page (template) right away.  It
usually shows up after a few hours.  It shows up right away on the
admin side though.  This leads me to believe that there is some sort
of caching going on, but I do not have any type of Django cache
setting going on in my settings.py file.  Is this a python cache
issue?  I've tried pkill python, but doesn't work either.  Is there a
template/web page cache in Django?

My host is Dreamhost, so I am running Django with FastCGI.  I know
thats not the preferred set up, but just getting my feet wet with
Django.  Thanks for any advice!

site/admin/doc error in django's model_detail.html using "filter escape" VS "autoescape"

[Scott SA]

I'm having a consistent problem across multiple projects with the self-
documentation and I'm hoping somone here might have an idea what is
wrong and how I might fix it. Thanks in advance for any assistance!

I have tried a couple of different versions of django including the
latest svn release and I consistently get the error:

"filter escape" is not permitted.  Use the "autoescape" tag instead.

nOOb alert, accessing set variables in template

[Mr. T]

Just start with Django and liking it a lot. Made a database and a page
that displays queries as html table. It was all too easy.

In one of my models I use a Foreign key to ref another object.

class A:


class B:
a = ForeignKey(A)

When I include A in the context of my template, I see that the
variable {{A.a_set}} is there. How could I "stringify" that set and
put it in one of the cells of my table?

How to setup Apache, mod_python and a reverse proxy to Lighttpd for Django on Ubuntu

[Alexis Bellido]

Hi guys, I've got my first 'serious' Django application running on a
production environment and after learning a lot from the great Django
community and extensive documenation I decided to give something back.

Here's a simple tutorial on how to setup Apache, mod_python and a
reverse proxy to Lighttpd for Django on Ubuntu:

Re: Admin won't display datetime widget with custom form?

[Keith Eberle]

I believe the idea is that if you override a field in your custom form, you
are then working off the default implementation of a field, which doesn't
include any of the niceties that the admin has added for you.

Named URL Patterns

[dkadish]

I'm having issues with a named URL pattern in my code. Django does not
seem to be finding the correct URL when the {% url %} and reverse( )
tag/functions are used.

the urls.py file at app_root/project/urls.py contains:

from django.views.generic import list_detail, create_update
from maverick.project.models import Project
from django.conf.urls.defaults import patterns, url
from django.core.urlresolvers import reverse

urlpatterns = patterns('maverick.project.views',
url(r'^$', list_detail.object_list, {'queryset':
Project.objects.all()}, 'project-home'),
url(r'^new$', create_update.create_object, {'model': Project,
'post_save_redirect': reverse('project-home')}, 'project-new'),
)

and I am referencing the URL pattern (in addition to in the second
link) in the file app_root/home/templates/base.html:




Maverick



Projects
Calibrations


{% block section_menu %}{% endblock %}


{% block content %}{% endblock %}


{% block footer %}{% endblock %}




If you need more information, just let me know what to post.

David

A much cheaper solution would be to create a list of range(20),
randomize that with shuffle and use successive elements to index the slice.

ordering a query set randomly

[Orcun Avsar]

hi,
problem is that i want to order model instances for an attribute and
slice it. then sort list randomly.

>>query=order_by("date")[:20]
>>query.order_by("?")
returns an error because query set has been sliced


>>query=order_by("date")[:100]
>>random.shuffle(query)
also returns error bacuse query set doesn't behave like a list and
doesn't support item assignment.

dirty solution was creating a list contains model instances by putting
query in a for loop then shuffle it. is there any alternative solution.

Re: [solved] Re: delete tables

[felix]

I just pulled it directly from django's source code.

I would only recommend doing syncdb in a development environment.  I just
use it as part of an import / convert from an old website's schema.

probably for what you are doing (a user doing something on a form) this is
too dangerous to do.

syncdb generates sql
checks for an admin user
and installs any initial_data fixtures

by looking at how it does that you should be to isolate just the commands
you want for just the application and db tables that you want.  look at
manage.py and keep following the code.

if you know which db you will be running on then maybe its better just to
delete the models and then reset the auto increment sequence using raw sql
as steve holden suggested.

maybe better is to delete all the models except for the 0 and 1
so they will still be there.

This is a single field? That's unfortunate.

Be careful: this isn't a string, it's a list with a single dictionary in
it (but that's really just picking nits). By "call it" I assume you mean
"retrieve it". I know it's tedious of me to correct you on these terms,
but you need to understand that you are dealing with a bunch of geeks
who ascribe precise technical meaning to terms like "call" ... anyway,
enough with the linguistics. And sorry if English isn't your first language.

The u stands for "Unicode", not "UTF". But you will note that "metadata"
isn't a Unicode string, it's a regular ASCII string, so Unicode doesn't
come into that.

You seem to have the basics correct, and

myProblemObject[0]

should indeed be a dictionary. Therefore

myProblemObject[0]['metadata']

will be the (Unicode) string (ignoring any wrapping the mail system does)

u"[['Image format', 'JPEG'], ['Image mode', 'RGB'], ['Image size',
'1280x960'], ['Compression', '14.0 times']]"

This means that
> myProblemObject[0]['metadata'][0]
will give you a single character, u"[", the first character from that
string.

I prefer to suggest that the way you are *storing* the data is a
problem, since it would really be better if your model had separate
fields for image format, image mode, image size (possibly separating
width and heigh) and compression. Otherwise youo will forever be
fighting to extract meaningful information form the data stored on the
database.

If you want a really dirty solution you could try

metadata = eval(myProblemObject[0]['metadata'])

which will give you a list of two-element lists, but this is very
fragile and extremely unsafe if anyone else can add to the database
contents.

Yup - just wasn't sure on that.  I had remembered seeing something along
those lines a while back but wasn't sure if it had said it *was* changing
names or *wasn't* :)  Plus with all of the chatter on both forms and
newforms I couldn't find a definitive answer to this question when
searching.

They have some other "old stuff-isms", some I noticed on my own, some were
easier to search on and I'm sure I'll come across more.

Thanks all :)

Oops. It could also read

in which case you should change it to

but I hope you've got the idea: basically newforms has *become* forms.

Getting lists/dictionaries out of the database

[timc3]

I am having a problem with getting lists/dictionaries out of the
database.

If I have for instance this in a field of my database:

[['Image format', 'JPEG'], ['Image mode', 'RGB'], ['Image size',
'1440x900'], ['Compression', '21.0 times']]

And I call it from django, I would get the following string:

[{'metadata': u"[['Image format', 'JPEG'], ['Image mode', 'RGB'],
['Image size', '1280x960'], ['Compression', '14.0 times']]", 'title':
u'Technical Metadata'}]

Because of the 'u' UTF it seems that I can't then properly use it as a
list with dictionaries like so:

myProblemObject[0]['metadata'][0]

Any ideas? I presume this is Django's handling of the data within the
database being the problem not a python problem in general?

Thanks..

If the statement that is failing used the recommended mechanism and reads

import django.newforms as forms

then you simply have to change it to

import django.forms

Otherwise you'll have to change every occurrence of "newforms" to
"forms". The code should work, though, modulo any incompatible changes
made to the newforms module before incorporation as the standard package.

This is correct. oldforms was removed, and newforms was renamed to
forms. This happened before the 1.0 release.

You just need to change your code to reflect this, and it should likely
work.

Re: Admin won't display datetime widget with custom form?

Enter Valid Date/Time ...

[dbee]

I keep getting the same stupid error ... "Enter valid date/time". I've
done everything I can think of to let django know that the value in
question can be blank ...

# Store the people who need reminding of things
class TeleInt (models.Model):

call_back = models.DateTimeField( null=True, blank=True )
meeting_date = models.DateTimeField( null=True, blank=True )


# Teleint
form
class TeleIntForm(ModelForm):

call_back = forms.DateTimeField(required=False)
meeting_date = forms.DateTimeField(required=False)

class Meta:
model = TeleInt

Yet i still get that error everytime. It's very, very annoying. Anyone
got any ideas ?

Technically, yes - but I failed to find a clean way to do so. Here's
some possible (*untested*) hack:

# project's urls.py

import photologue.urls
for purl in photologue.urls.urlpatterns:
callback = purl.callback
purl._callback = login_required(callback)

AFAICT, this _should_ work - but well, this is a (dirty) hack, and as
such is not garanteed in any way.


And if there's a better way (not requiring to rewrite all photologue
urls by hand), I'd be happy to know about it !-)

The first thing to understand is that in Python, everything is an
object - including functions. The second point is that functions are
mostly a specific case of callable objects - a callable object being
any object implementing the __call__ operator (iow : having a __call__
method). FWIW, classes (classes being objects too...) are callable
objects too (you call them to instanciate them).

IOW :
- you can use functions and classes like any other objects (passing
them as args, returning them from function, etc, etc)
- you can define your own callable types

Now : a decorator is a callable object that takes a (single) callable
object as argument and returns a (single) callable object.


FWIW, the

@decorator
def somefunc(...):
   # XXX

notation is only syntactic sugar for

def somefunc(...):
   # XXX
somefunc = decorator(somefunc)

If 0 and 1 have special significance as primary key values then it's
very fragile to rely on the database to insert them for you. Instead
you'd be better off writing them specifically.

It's not possible to reset the automatically generated IDs in a
platform-independent way because of the huge differences between (say)
PostgreSQL serials vs. Oracle sequences (which as far as I can tell
actually require a stored procedure to increment the sequence and insert
the value into a table, though I am no Oracle expert).

If you can suggest a suitable API then it might be considered for
inclusion into Django in some future version. The API reference is still
available, by the way, at

  http://docs.djangoproject.com/en/dev/topics/db/queries/

In the meantime you are left with raw SQL as the only suitable way to do
what you want, and the API documentation does give you some guidance as
to how to implement raw SQL. As for the exact details of the counter
reset, you'd need to tell us which database engine you are running against.

 Steve

login_required for imported apps

[Heather]

I have a couple of projects that use the same application
(particularly, photologue).  In one project, I want the views of the
imported application to require users be signed in.  All the views in
this imported application are generic.  So, is it possible to use
login_required w/o having to go into photologue.urls and add the
decorator?  Is it possible to do this in my projects urls file?  I am
new to Python so I'm not sure I'm on the right track but I thought I
should do something along the lines of writing my own wrapper that
would take  photologue.urls as an argument (the **kwargs argument,
maybe?)  Like:

@login_required
restrict_access(*args, **kwargs)
#if this is indeed the right idea, this is where I'm not quite
sure what to do...
if kwargs.list_object(*args, **kwargs)
  return kwargs.list_object

I know this isn't right but I am not 100% sure of the concept of
decorators.

thanks for any help.

The standard advice to run through the tutorial does mean the *whole*
tutorial. If you are interested in "just running it and getting a page"
all you need to do is skip ahead to section 3, at

  http://docs.djangoproject.com/en/dev/intro/tutorial03/

There you will see an explanation of URLs and views that should enable
you to strike out on your own if you don't want to follow the tutorial.
It's not like it's a secret or anything, simply that the tutorial puts
in a lot of material about models and the admin site before getting to
views that allow you to manipulate that model.

This ordering may not be the most helpful for an impatient beginner, but
it allows a patient one to relatively quickly get a good understanding
of how Django manipulates database content. The ability to use the admin
site to maintain data does meant the views are a little more interesting
when they do come along.

Yeah, actually I had the same problem with timezones in embedded mode,  
and some other weird problems with psycopg2, too. Daemon mode fixed  
all of them, and my experience bears out what Graham said: this setup  
handles more load than prefork with fewer processes and less memory,  
and the footprint's more predictable. There are other benefits, like  
the ability to run different sites as different users, but that was my  
main concern.

Re: everything works except apache seeing django app

[Stephen Moore]

for the record, I fixed the problem

it seems the permissions have to be correct for every level of the directory.

so for /home/iambo/web then /, /home, /home/iambob and
/home/iambob/web had to have the right permissions :)

thankyou for the help.

Re: delete tables

[Mirto Silvio Busico]

Sorry  I was not clear.

I have some utilities in view.py which have to reload tables content 
(migration from the legacy database; clearing a table and reloading with 
base content; ...)

I know from the shell it is enough an "python manage py flush", but I 
have two problems:

* the action have to be triggered by a user action on a form
* the id have to be resetted because for me the id=0 and id=1 rows
  have a fixed special meaning

I have not found anything about deleting tables in 
http://docs.djangoproject.com/en/dev/topics/db/queries/ (it seems that 
"database api" has gone in 1.0)
The only thing that seems I can use is "Executing custom SQL" in 
http://docs.djangoproject.com/en/dev/topics/db/models/

There is a better/recommended method?

Thanks
Mirto

Re: How to get a page in Django?

[chaugen]

I am new to both Python and Django, and with somewhat limited
programming experience. That being said, the tutorials set up on
Django Project (http://docs.djangoproject.com/en/dev/) are excellent.
I would suggest 'Beginning Python' from O'Brien as well. It took me
only a few days with both the tutorials, and the book to begin
developing some very dynamic web projects. One other resource may be
helpful is 'Practical Django Projects', which will help you build a
Content Managment System and 'get a page in Django!'.

Re: Admin won't display datetime widget with custom form?

[Keith Eberle]

I had a project where I needed to set the initial value to the current
week's week ending date (Sat), so I needed a custom form too.  I used the
AdminDateWidget, but I think this will be the correct widget for your needs.

# import the widgets
from django.contrib.admin import widgets

# use the widget on this line
date = forms.DateTimeField(widget=widgets.AdminSplitDateTime)

If you want yet another hack you could use a custom authentication
backend with your own user model as described here:

Need help with newforms ...

[dbee]

I need the user to be able to check the box on groups that apply to
them. This was really easy to do with oldforms ...

   VIEWS:

# Get all that user's
groups
groups =
Groups.objects.filter(userProfile__user__pk=request.user.id)

# Create the FormWrapper, template, context, response
form = forms.FormWrapper(manipulator, new_data, errors)

return render_to_response('myaccount.html', {'form': form,
'user' : request.user,'groups' : groups})


   TEMPLATE:

  {% for g in groups %}

   
 
  {{ g.name }}
 
 
  
 
   

   {% endfor %}

Couldn't be simpler. But now in newforms, i'm a bit lost ...

  VIEWS:

# Get all that user's
groups
groups =
Groups.objects.filter(userProfile__user__pk=request.user.id)


# Campaign
form
class CampaignsForm(forms.Form):

  name = forms.CharField(required=True, max_length=40)
  description = forms.CharField(required=True,
max_length=1000,
widget=forms.Textarea(attrs={'rows':'7','cols':'25'}))
  send_date = forms.CharField(required=False)
  groups = forms.CharField(widget=forms.Select())

  def __init__(self, groups, *args, **kwargs):

   super(CampaignsForm, self).__init__(args, kwargs)
   self.fields['groups'].choices = groups

# THis gives me a an empty groups drop-down menu and triggers all
the errors on the form. I also especially want to render checkboxes
using only that user's groups and not have a drop-down menu.

Thanks

Re: Django server crashes without error

[ccpn]

I just updated everything, we are using python-mysql 1.2.2 and
MySQL Client API version 5.1.26-rc, which I think are the very latest
versions
The crashes still occur though. Is there any logfile that tracks what
is going wrong?

OK - I seem to have found the problem.

Line 113 of ldapauth.py:

self.ldap.set_option(k, self.settings.LDAP_OPTIONS[k])

should be:

self.ldap.set_option(k, self.settings["LDAP_OPTIONS"][k])

I presume that other instances of that syntax need to be changed.

Also, the syntax for settings.py that worked for me were:

import ldap
LDAP_OPTIONS = 'ldap.OPT_X_TLS_DEMAND,1'

I have commented on the ticket.

Thanks for all the help and suggestions.

Daniele

Promote a Place to a Restaurant?

[Erik Stein]

Hello --

I could not get an answer on the IRC channel and I'm also not finding  
the right keywords for a successful search on the subject[1]:

You all know the model inheritance example with the classes Place and  
Restaurant. Imagine I mapped every Place in my street, now one of this  
empty places is becoming a restaurant. Is there an easy way to express  
this in django-ORM?

I tried

p = Place(number=32)
p.restaurant.create()

which gives

DoesNotExist: Restaurant matching query does not exist.

Am I missing something or is this just not implemented? Is there a  
workaround?


Thanks

AFAICT, there's some work going on to allow to replace the default
User model with a custom one. But so far, the recommended solution is
indeed to use a UserProfile. Else, there's the hackish (IOW : *not*
recommended) solution - monkeypatching the User model

SQLite is not Python. So I guess you *really* dont know anything about

Ok, I guess you have a profound misconception about what Django is and
is not. So to try and make things clear :  Django is *not* a Content
Management System. It is a web programming framework - that is, a
*development* tool. Unless you're interested in becoming a programmer,
it's probably not what you're looking for.

If you want to get rid of Django-provided translations (these from  
django/conf/locale/), you have to turn off i18n completely by  
switching USE_I18N to False.

Anyway, I am not sure what happens if Django gets more that one  
translation for the same key (is there any order of preference?), I  
just never tried it.

Re: How to display image from ImageField in ModelAdmin?

Code above was a bit incorrect. Here better solution:
## widget declaration
from django.utils.safestring import mark_safe
from django.forms.widgets import FileInput

class AdminImageFieldWithThumbWidget(FileInput):

def __init__(self, thumb_width=50, thumb_height=50):
self.width = thumb_width
self.height = thumb_height
super(AdminImageFieldWithThumbWidget, self).__init__({})

def render(self, name, value, attrs=None):

thumb_html = '' %
(value.url, self.width, self.height)
return mark_safe("%s%s" % (thumb_html,
super(AdminImageFieldWithThumbWidget, self).render(name, value,

##form sample

thumb_width = 50
thumb_height = 50
