Re: Meta inheritance across abstract base class
Hi, Ohh. Yup. I didn't read that carefully enough. That behavior doesn't seem expected to me. Expecially considering this sentence: "if the child does not specify an ordering attribute or a get_latest_by attribute, it will inherit these from its parent."

Re: Meta inheritance across abstract base class
Hi, If you define a new class Meta on C, then it will _replace_ the previous class Meta. You can, however have class Meta inherit other class Meta. class Student(CommonInfo): # ... class Meta(CommonInfo.Meta): db_table = 'student_info' https://docs.djangoproject.com/en/dev/topics/db/models/#meta-inheritance Collin On Monday, November 24, 2014 8:19:50 AM UTC-5, Torsten Bronger wrote: > > Hallöchen! > > I have the following model structure: > > class A(models.Model): > ... > class Meta: > ordering = ["timestamp"] > get_latest_by = "timestamp" > > class B(A): > class Meta(A.Meta): > abstract = True > > class C(B): > ... > > Then, class C doesn't haven ordering or get_latest_by set.

Meta inheritance across abstract base class
Hallöchen! I have the following model structure: class A(models.Model): ... class Meta: ordering = ["timestamp"] get_latest_by = "timestamp" class B(A): class Meta(A.Meta): abstract = True class C(B): ... Then, class C doesn't haven ordering or get_latest_by set. Is this expected behaviour? Then, I would simply re-define them in B.
