DoesNotExist behavior in db.models query.py

I have been tripping over the following exception

DoesNotExist: INSERT_YOUR_MODEL_NAME_HERE matching query does not exist.

The error is source in django 1.11.2 in db.models query.py file, in the get(self, *args, **kwargs) function, line 378 to be exact

...
    raise self.model.DoesNotExist(...)
...

This throws a 500 error and I would like my code not to throw a 500 error in this situation, rather a customized message more along a 4xx error e.g.

{"message": "record matching identifier A and identifier B not found in database"}

rather than a 500 error.

It seems to me that my only choice right now is to subclass QuerySet and write my own version of the get(self, *args, **kwargs) method. Is that my only choice or is there a django parameter I can set so that 0 matching results does not return a 500?

Or do I need to intercept the 500 error somewhere else.

Sorry, am a bit of a newbie to django internals, all help and advice is appreciated.

Thanks,

Steve
