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
