Add custom exception handling class per APIView

[lipka]

Would it be possible to add custom exception handling per each APIView? It could just follow the same style[1] as all the other classes and just fallback to the original behavior if not set.

You can simply override the handle_exception on a per view basis (https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/views.py#L413).

@xordoquy That is indeed possible, but then you have to override (and possible copy+paste) the entire method just to change the particular exception_handler. Doesn't feel like a very DRY approach.

Would you consider having this as a feature if I can come up with a PR?

Not something we'd support no. The exception handler should be a global case. For more specific cases write the view logic explicitly.

In recent versions, you can override get_exception_handler and return your custom handler for a specific APIView/ViewSet. See PR #4753 for more info.
