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'

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.

Tschö,
Torsten.
