Comment (by charettes): Replying to [comment:5 MatthewWilkes]: > I don't believe that IsNull lookups should be converting their values to the type of the parent field, however the RelatedLookupMixin has useful looking code for ensuring that MultiColSource is handled correctly. > > Would the fix for this be as simple as: > > {{{ > class RelatedIsNull(RelatedLookupMixin, IsNull): > def get_prep_lookup(self): > return self.rhs > }}} > ? `return super(RelatedLookupMixin, self).get_prep_lookup()` would be more appropriate. -- Ticket URL: <https://code.djangoproject.com/ticket/26983#comment:6> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
