How to return HTTP 400 response in Django?
I want to return a HTTP 400 response from my django view function if the request GET data is invalid and cannot be parsed.
How do I do this? There does not seem to be a corresponding Exception
class like there is for 404:
raise Http404
Solution 1:
From my previous comment :
You can return a HttpResponseBadRequest
Also, you can create an Exception subclass like Http404 to have your own Http400 exception.
Solution 2:
You can do the following:
from django.core.exceptions import SuspiciousOperation
raise SuspiciousOperation("Invalid request; see documentation for correct paramaters")
SuspiciousOperation is mapped to a 400 response around line 207 of https://github.com/django/django/blob/master/django/core/handlers/base.py
