Ticket #6804: hack.diff

File hack.diff, 933 bytes (added by floguy, 17 years ago)
This does special case checking to see if it's a RelatedObject and if so, doesn't raise a JoinError. This causes one test to break, and that's because I don't understand the implications of the change that was made. Maybe this hack can be expanded upon to get a real solution. (Using patch #6095)

 from django.core.exceptions import FieldError
 from datastructures import EmptyResultSet, Empty, JoinError
 from constants import *
+from django.db.models.related import RelatedObject
 try:
     set
 …
                     names = opts.get_all_field_names()
                     raise FieldError("Cannot resolve keyword %r into field. "
                             "Choices are: %s" % (name, ", ".join(names)))
             if not allow_many and (m2m or not direct):
+            if not allow_many and (m2m or not direct) and not isinstance(field, RelatedObject):
                 for alias in joins:
                     self.unref_alias(alias)
                 raise JoinError(pos + 1)
