如何继承基于类的视图的DRF权限？

Question

class ViewTwo(APIView):
    permission_classes = (permissions.IsBar,)

class ViewThree(ViewTwo):
    permission_classes = (permissions.IsXYZ,)

ViewThree如何继承ViewTwo权限才能同时拥有permissions.IsBar和permissions.IsXYZ权限类？

Answer 1

我想，您需要在get_permissions中实现ViewThree方法，该方法实例化并返回此视图所需的权限列表：

class ViewThree(ViewTwo):
    def get_permissions(self):
        return super().get_permissions() + (permissions.IsXYZ,)

Answer 2

通过追加ViewTwo的权限来简单地定义ViewThree的权限。

class ViewTwo(TemplateView):
    permission_classes = (permissions.IsBar,)

class ViewThree(ViewTwo):
    permission_classes = ViewTwo.permission_classes + (permissions.IsXYZ,)
