How to add @property to the base Group model in Django?

Question

I want to be able to add a property to the group model

This is what I have been trying

from django.contrib.auth.models import Group

class GroupExtensions(Group):
    class Meta:
       proxy = True

    @property
    def assigned_property(self):
        return 'something'

I want to get this property from the base group model but somehow this doesn't work

group_instance.assigned_property 

Where group_instance is an instance of the Group model

Answer 1

This behaviour is explained here. So the only way for you to be able to use assigned_property is to query the groups through GroupExtensions. But there is a way to make this work, although you should be careful about doing this:

group_instance.__class__ = GroupExtensions
print(group_instance.assigned_property)
