Generic foreign keys and the sqlite3 memory database (for unit testing)
have recently stopped working for me. I upgraded my sqlite3 version
and Django, so am not sure what change caused the problem.
Following is a simple models file that demonstrates the problem. I
have no problem when using sqlite with a file-based database.
Versions of software I'm running:
Django: Today's trunk
sqlite3: 3.3.7_0+darwin_8
pysqlite: 2.3.2
Model file:
-----------------------------------------------
from django.db import models
from django.contrib.contenttypes.models import ContentType
def test_all():
"""
>>> msg = Message(title="hi")
>>> msg.save()
>>> msg
<Message: Message object>
>>> tag = msg.tags.create(tag="sometag")
>>> tag
<Tag: Tag object>
>>> assert tag.content_object is not None
"""
class Tag(models.Model):
tag = models.SlugField()
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
content_object = models.GenericForeignKey()
class Message(models.Model):
title = models.CharField(maxlength=100)
tags = models.GenericRelation(Tag)
