Inlineformset without foreign key possible?
Layne Sadler
I'm trying to implement an inline formset for two models in a graph database. The problem that I'm running into is that formsets are designed with foreign keys in mind.
I'm relating a model to itself through another model. For simplicity sake, let's call them a Person model and a FriendRel model:
Person -[FRIENDS_WITH]-> Person
FriendRelFormSet = inlineformset_factory(Person, FriendRel, form=FriendRelForm, extra=1)I've tried setting the fk_name=None argument, but I am still met with the following error:
ValueError: 'django_rel.RelationshipMeta' has no ForeignKey to 'django_node.NodeMeta'.
So now I am looking into the documentation below, but it is a bit abstract for my skillset. Am I banging my head against the wall with this, or is it possible to avoid the whole foreign key thing?

I’m not able to wrap my head around your specific application, but if you don’t want to use a ForeignKey on a formset, don’t use an InlineFormset.
Just use a regular BaseFormset.
