How to check model fields type?
I have an API class that we use across our app that lets us to simplify HTTP request and create new API end points by just assining what model to use, without needing to write custom handler for each model request.

I know how to do deal with wild cards and do wild card searches, but I want to know how I can check if the any given field is a text field?

Filtering and searching with Django Rest Framework
I'm doing my first DRF project and wondered if it's possible to use the DjangoFilterBackend for filtering specific fields and use a search Filter at the same time. So a request would look something like: http://localhost:8000/api/v1/test/?search=test&id=27&author=2672 Is it possible to do this with DjangoFilterBackend or would I have to write my own filter logic? If you need more information on the project itself or my code just let me know :) -
