Description
njharman (lists@…) reports:
class Foo(models.Model):
myfield = models.OneToOneField('SomeModel', to_field='id')
Works.
class Foo(models.Model):
myfield = models.OneToOneField('SomeModel')
Fails because whatever "turns" 'SomeModel' from string into class object
hasn't happened when code in
"/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/django/db/models/fields/related.py
on line 510 tries to determine default to_field.
Model is ok during syncdb; failure occurs during import.
