Django REST framework QueryFields documentation — Django REST framework QueryFields documentation (original) (raw)
Allows clients to control which fields will be sent in the API response. The idea is based on a recipe described in the official documentation, Dynamically modifying fields, adapted to allow API users to specify fields via GET request query parameters.
Doing the filtering server-side instead of client-side can have advantages:
- Fewer bytes down the wire = snappier ajax for your webapps
- Less backend server load if expensive-to-serialize fields go unneeded
- For thin clients; a better choice if client-side is a dumb/low-power device
