Description
In short: if referenced obj. is saved after attaching to a referencing obj. its id field (i.e. <refrerenced_obj>_id) there remains None.
In details:
class ReferencedObj(Model):
...
class ReferencingObj(Model):
referenced_obj = ForeignKey(ReferencedObj)
...
x = ReferencedObj()
y = ReferencingObj()
y.referenced_obj = x
x.save()
y.save() -----→ NOT NULL constraint failed: ..._referencingobj.referenced_obj_id
