How to display a custom error page for HTTP status 405 (method not allowed) in Django when using @require_POST
My question is simple, how do I display a custom error pa开发者_如何学运维ge for HTTP status 405 (method not allowed) in Django when using the @require_POST
decorator?
I'm using the django.views.decorators.http.require_POST
decorator, and when the page is visited by GET request, the console shows a 405 error, but the page is just blank (not even a Django error page). How do I get Django to display a custom and/or default error page for this kind of error?
EDIT:
It's worth mentioning that I've tried putting a 404.html, 500.html and 405.html page in my templates folder - but that does not help either. I have also varied between DEBUG = True
and False
, to no avail.
You have to write custom Django middleware. You can start with this one and extend it to check if 405.html file exists and so on:
from django.http import HttpResponseNotAllowed
from django.template import RequestContext
from django.template import loader
class HttpResponseNotAllowedMiddleware(object):
def process_response(self, request, response):
if isinstance(response, HttpResponseNotAllowed):
context = RequestContext(request)
response.content = loader.render_to_string("405.html", context_instance=context)
return response
Check docs if you don't know how to install middleware:
http://docs.djangoproject.com/en/dev/topics/http/middleware/
You can also check this article:
http://mitchfournier.com/2010/07/12/show-a-custom-403-forbidden-error-page-in-django/
If you look into the documentation and the source code of django.views.defaults you see that only 404 and 500 errors are supported in a way that you only have to add the 404.html resp. 500.html to your templates directory.
In the doc. you can also read the following
Returning HTTP error codes in Django is easy. There are subclasses of HttpResponse for a number of common HTTP status codes other than 200 (which means "OK"). You can find the full list of available subclasses in the request/response documentation.
Thus if you want to return a 405 error, you have to use the HttpResponseNotAllowed class
An example
I'm not sure that's possible. Perhaps you should consider filing a bug report.
I landed here in 2022. The above accepted answer is not working for me. I use django rest framework. My sollution was to create a middleware with
#app/middleware.py
from django.http import HttpResponse
from django.template import loader
class HttpResponseNotAllowedMiddleware:
def __init__(self, get_response):
self.get_response = get_response
# One-time configuration and initialization.
def __call__(self, request):
# Code to be executed for each request before
# the view (and later middleware) are called.
response = self.get_response(request)
# Code to be executed for each request/response after
# the view is called.
if response.status_code == 405:
context = {}
template = loader.get_template('app/405.html')
return HttpResponse(template.render(context, request))
return response
then install it by adding this to settings
MIDDLEWARE = [
.......
'app.middleware.HttpResponseNotAllowedMiddleware',
]
the 405.html template is just a plain not allowed text
