I'm having a problem with Django 1.2.4.
Here is a model:
class Foo(models.Model):
# ...
ftw = models.CharField(blank=True)
bar = models.ForeignKey(Bar, blank=True)
Right after flushing the database, I use the shell:
Python 2.6.6 (r266:84292, Sep 15 2010, 15:52:39)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from apps.foo.models import Foo
>>> Foo.objects.all()
Traceback (most recent call last):
File "<console>", line 1, in <module>

return self.cursor.execute(query, args)
DatabaseError: column foo_foo.bar_id does not exist
LINE 1: ...t_omg", "foo_foo"."ftw", "foo_foo...
What am I doing wrong here?
Update: If I comment out the ForeignKey
, the problem disappears.
Update 2: Curiously, this unit test works just fine:
def test_foo(self):
f = Foo()
f.save()
self.assertTrue(f in Foo.objects.all())
Why does it work here but not in the shell?
Update 3: The reason it works in unit testing but not the shell may have something to do with the different databases being used:
settings.py:
DATABASES = {
'default': {
'ENGINE': 'postgresql_psycopg2',
'NAME': 'foo',
'USER': 'bar',
'PASSWORD': 'baz',
'HOST': '',
'PORT': '',
}
}
import sys
if 'test' in sys.argv or True:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': 'testdb'
}
}
Update 4: Confirmed that when I use SQLite3 as the db, everything works fine.
Try completely dropping/wiping the database before running syncdb.
I remember needing to do that a while back when I had made changes to foreign key fields.
