#12731 closed (fixed)

Manager.raw() doesn't work with Multi-table inheritance

As far as I can tell the Manager.raw() function does not work with a subclassed model. I believe the raw function is looking for an 'id' field, and this does not exist in a subclassed table (instead of id, there is a <parent>_ptr_id field).


class Parent(models.Model)
 name = models.CharField(max_length=50)

class Child(Parent)
 favorite_toy = models.CharField(max_length=50)

# broken code
Child.objects.raw("SELECT * FROM child")
