Hi everyone. I've been using django for almost a year now, but it's my first time posting here.
Anyway, I'm encountering an error which I think might be a bug. I've yet to try and replicate it as I thought posting here would be the better first step, as I might just be doing something incorrectly. When I try a query with .exclude() on a table with a GenericForeignKey and a reverse Generic Relation on a different table, I get this: AttributeError at /list 'GenericRelation' object has no attribute 'field' Here is a mock up of my database structure: class InternalOffer(models.Model): user = models.ForeignKey('User') status = models.CharField(max_length=64) (more offer data...) relation = GenericRelation(OfferJoin, related_query_name='offerquery') class ExternalOffer(models.Model): user = models.ForeignKey('User') status = models.CharField(max_length=64) (more offer data...) relation = GenericRelation(OfferJoin, related_query_name='offerquery') class OfferJoin(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() offer = GenericForeignKey('content_type', 'object_id') I can filter fine, it's only the exclude that causes errors. Here is the code that causes the error: offers = OfferCover.objects.filter(offerquery__user__id=request.user.id) offers = offers.exclude(offerquery__status="Completed") Here's the full callback: Django Version: 1.8.2 Python Version: 2.7.6 Traceback: File "/Library/Python/2.7/site-packages/django/core/handlers/base.py" in get_response 132. response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/Library/Python/2.7/site-packages/django/contrib/auth/decorators.py" in _wrapped_view 22. return view_func(request, *args, **kwargs) File "/Users/path-to-project/project/views.py" in list 136. offers = offers.exclude(o__status="Completed") File "/Library/Python/2.7/site-packages/django/db/models/query.py" in exclude 686. return self._filter_or_exclude(True, *args, **kwargs) File "/Library/Python/2.7/site-packages/django/db/models/query.py" in _filter_or_exclude 695. clone.query.add_q(~Q(*args, **kwargs)) File "/Library/Python/2.7/site-packages/django/db/models/sql/query.py" in add_q 1304. clause, require_inner = self._add_q(where_part, self.used_aliases) File "/Library/Python/2.7/site-packages/django/db/models/sql/query.py" in _add_q 1332. allow_joins=allow_joins, split_subq=split_subq, File "/Library/Python/2.7/site-packages/django/db/models/sql/query.py" in build_filter 1180. can_reuse, e.names_with_path) File "/Library/Python/2.7/site-packages/django/db/models/sql/query.py" in split_exclude 1562. trimmed_prefix, contains_louter = query.trim_start(names_with_path) File "/Library/Python/2.7/site-packages/django/db/models/sql/query.py" in trim_start 1989. join_field = path.join_field.field Exception Type: AttributeError at /list Exception Value: 'GenericRelation' object has no attribute 'field' I've read the documentation multiple times and haven't come across anything usefull. I know that filtering GFKs alone won't work, but both filtering and excluding should work with the reverse Generic Relation.
