Might want to check out request.is_ajax(). It does essentially the same thing; it'd just change line 14.

Maybe returning a HTTP-Code in the 400 range ('Bad Request') would be more appropiate?

Thanks for the snippet.

I agree that you could replace request.META.get with request.is_ajax() and return a HttpResponseBadRequest instead, however this is still a very useful snippet!

I've updated the code with your recommendations. Thank you!

You have to make a instance of HttpResponseBadRequest.
