Description (last modified by )
Hello Django Team,
I'm encountering an issue with the django-admin dumpdata command when trying to serialize a model with a ManyToMany relationship to a custom User model. This custom User model inherits from another User model defined in a different app.
It appears that Django is using the default manager of the custom User model, rather than its base manager. This custom manager includes prefetch_related calls in its get_queryset function, which I suspect is causing the issue.
I've attached a Dockerized Django app that replicates this behavior. You can also find it on GitHub: https://github.com/Martini991/django-dumpdata-bug.
For reference, I’ve reviewed two related tickets, but they seem to address different issues:
https://code.djangoproject.com/ticket/35238
https://code.djangoproject.com/ticket/35159
Thank you for your assistance!
