Django No Exceptions

Django No Exceptions provides middleware to catch certain exceptions that correspond to HTTP response classes. It was inspired by Django's Http404, and is used similarly.

Usage

Setup

• Add 'no_exceptions.middleware.NoExceptionsMiddleware', to your MIDDLEWARE_CLASSES
• Optionally set LET_HTTP_EXCEPTIONS_500 (True/False) to determine whether to catch NoExceptions exceptions or to pass them through as normal exceptions.
  This setting defaults to DEBUG (pass exceptions through in DEBUG mode, turn them into appropriate responses in production).

Using NoExceptions exceptions

from no_exceptions import exceptions as x

def my_view(request, \*args, \**kwargs):
    ...
    if request.is_bad():
        raise x.Http400("You need to foo your bar!")
    ...

Exceptions available are:

Http400 - CLIENT ERROR
Http401 - UNAUTHORIZED
Http403 - FORBIDDEN

Django's own Http404 is also available unchanged in no_exceptions.exceptions

You may also use no_exceptions.exceptions.HttpException to make your own exceptions on the fly:

def my_view(request, \*args, \**kwargs):
    ...
    raise x.HttpException(
            status=418,
            message="I can't help you, I'm a teapot"
    )
    ...
