#28988: Multi-table inheritance breaks GenericRelation querying -----------------------------------------+------------------------ Reporter: robwa | Owner: nobody Type: Uncategorized | Status: new Component: Uncategorized | Version: 1.11 Severity: Normal | Keywords: Triage Stage: Unreviewed | Has patch: 0 Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | -----------------------------------------+------------------------ Minimal example to reproduce. Create two models:
{{{ #!python class Generic(models.Model): content_type = models.ForeignKey('contenttypes.ContentType') object_id = models.PositiveIntegerField() obj = GenericForeignKey() class Vehicle(models.Model): associations = GenericRelation('Generic', related_query_name='vehicles') }}} Create a `Vehicle` and a `Generic` object pointing to the `Vehicle`. The following query returns the expected result: {{{ In [2]: Generic.objects.filter(vehicles__id=1) Out[2]: <QuerySet [<Generic: Generic object>]> }}} Add a third model. Don't change any data. Now the query returns an empty query set: {{{ #!python class Bike(Vehicle): pass }}} {{{ In [2]: Generic.objects.filter(vehicles__id=1) Out[2]: <QuerySet []> }}} -- Ticket URL: <https://code.djangoproject.com/ticket/28988> 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.
