Description
When the to_field of a ForeignKey field is specified as something other than the primary key, FK lookups do not work properly in filtering. The to_field is ignored, because the django/db/models/query.py:lookup_inner() function follows a pk (as of revision 7138, this is at line 1031).
There's probably a better way to get the field name than I've got in this patch, and I imagine there may be more safety checking than I'm doing. But this fixed my problem.

Feels like a dupe of #4306, which is fixed in queryset-refactor. Please reopen if you can demonstrate that this is not the same issue.
