Issue #2970
closedREST API silently ignores object attributes that don't exist on the serializer
Description
When creating an object through the DRF-based REST API, if you include attributes that are not part of the model or serializer, they are silently ignored. That should instead result in a failed/rejected request.
I discovered this by trying to create a FileImporter and supplying a "feed" attribute. This was a mistake, because the attribute is named "feed_url". My "feed" was silently ignored, and it wasn't until I tried to sync that I discovered something was wrong.
