• Can you please edit the question and share the full traceback. – willeM_ Van Onsem Commented Feb 15 at 18:09

• 1 But you print(..) the reverse lookups yourself? – willeM_ Van Onsem Commented Feb 16 at 6:20
• Please give us a traceback coming from actually running Django and not just trying to print the lookups in a notebook. When you run the code like you've done we have to make assumptions about you setting up your notebook correctly to work with your Django project which we otherwise wouldn't have to. – Abdul Aziz Barkat Commented Feb 16 at 10:14

I just added __init__.py to the admin directory

from apps.chat.admin.admin import ChatRoomAdmin, MessageAdmin

__all__ = ['ChatRoomAdmin', 'MessageAdmin']
