Formset.save for model with foreign key to concrete base model — at Initial Version
Description ¶
class A(models.Model): pass class B(A): pass class C(models.Model): some_model = models.ForeignKey(SomeModel) a_link = models.ForeignKey(A)
I'm using an inlineformset_factory where the parent model is SomeModel and the child model is C.
When calling formset.save() I'm getting an error from django/forms/models.py (line 910)
910: pk_value = getattr(self.instance, self.fk.remote_field.field_name) 911: setattr(obj, self.fk.get_attname(), getattr(pk_value, 'pk', pk_value))
The getattr call fails
if I wrap both lines in: if hasattr(self.instance, self.fk.remote_field.field_name):
it works good.
Not sure if the condition is the way to fix the bug or it's just preventing the original cause from happening.
