Django Foreign key's do not track the models DB when the model is
inherited from abstract class.
{{{
class A(Model):
class Meta:
abstract = True
class B(A):
pass
class C(Model):
fk = foreignkey(B,on_delete=models.CASCADE)
}}}
now model B is in table 1 and C points to table 1.
{{{
class A(Model):
pass
class B(A):
pass
class C(Model):
fk = foreignkey(B,on_delete=models.CASCADE)
}}}
Now Model B is in table 2 with Model A, however C is still pointing to
table 1, which leads to a foreign key mismatch error when you try to add
an instance of B
