Description (Last modified by russellm)

njharman (lists@knoggin.com) 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.
