Django Rest Framework provides some incredible tools for serializing data, but sometimes you need to combine many serializers and/or models into a single API call. drf-multiple-model is an app designed to do just that.
(from the documentation)
Well, I guess you found your answer but if someone else has the same issue, perhaps this is what is missing:
pip install django-rest-multiple-models
Make sure to add drf_multiple_model to your INSTALLED_APPS and then simply import the view into any views.py.
