Django权限继承问题和Meta

问题描述

我知道如果超类具有abstract = True，则可以继承Meta，否则不能继承。这是因为Django以某种方式消耗并从具体类中删除了Meta类？我想在下面的例子中做一些事情，所以Derived可以从Base获得Meta属性（在这种情况下，作为django-guardian的一部分继承权限）。

I understand Meta can be inherited if the superclass has abstract=True, but can't be inherited otherwise. Is this because Django somehow consumes and removes the Meta class from concrete classes? I'd like to do something as in the example below, so Derived can get the Meta properties from Base (in this case, to inherit permissions as part of django-guardian).

对于如何实现这一点的建议将不胜感激。

Suggestions on how to achieve this would be appreciated.

Ian

class Base(Model):
    class Meta:
        permissions = (("foo", "Allowed to do foo"),)

class Derived(Base):
    class Meta(Base.Meta): pass
