I am using pdfLaTeX to generate the PDFs on the fly and serve them via 
Django after dumping ReportLab.

Considering that the Curse guys hang around in #pocoo, that's well 
possible.

I just took a look - the design is definitely good. The examples of 
polish sites using Django are also a good idea.

Maintaining such a list is pretty important. We (the german Python 
community) try to maintain a list of Python hosters over here in Germany, 
but unfortunately there are not that many yet.

I just added the patch to my patch queue and it worked perfectly - thanks 
a lot! It would be great to get Django fixed.

Yesterday I was thinking it was my error, if I have some time I'll take a 
look into the functions you describe in the ticket.

Admin Inline does not want to edit

[Marek Kubica]

Hi,

I fought against this for the whole day already (with patching Django; 
creating Form and FormSet subclasses etc.) but nothing helped. I want to 
have a Message with multiple translations in my database and the admin 
should display the message and the translations inline.

Now the problem is, that the following works and sometimes saving in the 
admin fails with "Please correct the errors below." and no errors below 
that. When I patched the template to show {{ errors }} I also get this:

Translation with this None already exists.

When I take a look on the errors of the translation formset I get this:

[{'id': [u'Translation with this None already exists.']}, {}]

The only solution this far was creating a new message, copying stuff over 
and deleting the old one. 

I'm running the current Django trunk, but this has been broken for quite 
some time.

The relevant files look like this:

admin.py

from sys import maxint
from django.contrib import admin
from pointtec.transdigest import models

class TranslationInline(admin.TabularInline):
model = models.Translation

class MessageAdmin(admin.ModelAdmin):
ordering = ('text',)
list_per_page = maxint
search_fields = ('text',)
inlines = [TranslationInline]

admin.site.register(models.Message, MessageAdmin)

models.py:

from django.db import models
from django.conf import settings
from django.utils.translation import get_language, gettext_lazy as _

languages_available = settings.LANGUAGES

class Message(models.Model):
"""A message which is to translate"""
text = models.TextField(_('original message'), unique=True)

def __unicode__(self):
"""A nice representation for the user"""
return self.text

def save(self, *args, **kwargs):
self.text = self.text.strip()
super(Message, self).save(*args, **kwargs)

class Translation(models.Model):
"""Translation"""
message = models.ForeignKey(Message)
language = models.CharField(_('language'), max_length=5,
choices=settings.LANGUAGES)
translation = models.TextField(_('translation'))

def save(self, *args, **kwargs):
self.translation = self.translation.strip()
super(Translation, self).save(*args, **kwargs)

def __unicode__(self):
return u"%s: %s" % (self.language, self.translation)

It would be really nice if someone could show me what I'm doing wrong.

regards,
Marek

Achtually, you do not need to modify *anything* inside of Django. You just
implement it separately and maybe it gets included in django.contrib. You
should take a look at
http://www.djangoproject.com/documentation/contributing/

Use django-multilingual or django-utils (nesh.translation). Yesterday I
started my own translation system which works like nesh.translation.

I think something like this could go in django.contrib. But I'm not sure
how many people need this. Anyway, there already is some i18n system in
Django. Of course, it does not work well with content from the database.

Re: Adding attibutes to models via mixins

Thanks, I think I've made it. Unfortunately, there are still some rough
spots which I I'd like to fix (my metaclass overwrites any existing fields
without any warnings, but at least it's documented so, it's not that bad).
But this is rather low-priority unless someone comes up with a nice
solution.

The snippet can be found at:
http://www.djangosnippets.org/snippets/245/

With 137 lines it's a rather huge snippet but it is used as module, so
including it into ones own code shouldn't be a problem.

In case anyone has any improvements: I'd be happy to hear about them!

regards,
Marek

Adding attibutes to models via mixins

[Marek Kubica]

Hi all!

I've got a normal model and I would like to add additional functionality
via a mixin-class. This works quite well, until I tried to modify some of
the attributes of the model from my mixin.

I've got two fields which both fail to be set, but in different ways:
 - setting 'objects' to a custon manager from the mixin does not work at
   all: the class carries on having the dafault manager. I think this is
   because of some code in Django that adds a default manager without
   caring whether there was already one or not.
 - adding a database-field like position = models.Integerfield() seems to
   work (at least the attribute is in the right place) but unfortunately
   manage.py sql (and syncdb probably as well) does not find the
   mixin-injected field.

Have you any ideas on how to accomplish this?

regards,
Marek
