Hello, when I tried to add a MoneyField in one of my model, I get this error trace:

ValueError: Could not find manager MoneyManager in djmoney.models.managers.
Please note that you need to inherit from managers you dynamically generated with 'from_queryset()'.

I have already searched it and found this issue #590 and the response. The problem is that when I use the solution found on the note, which is to encapsulate my custom manager with money_manager, the error persists.

Do you have any idea on how I can solve it ?

Workaround: add use_in_migrations = False to your manager class
