#11938 closed (duplicate)

`to_field` does not function as expected.

Description

In lookups involving a ForeignKey, or a ManyToMany intermediary table using a to_field they fail due to looking for the primary key, rather than the field specified by to_field.

For example:

    user = models.ForeignKey(User, to_field="username")
    # Fails
    SimpleModel.objects.get(user=self.user)

This is a dupe of #11319, which is itself an amalgam of #10243 and #10785.
