Is it possible to render a template from middleware?
I have a middleware that does some processing. On certain conditions it raises an exception and the user sees my 500.html
template - correctly responding to 500 http status.
Now, on some exceptions I would like to render different template than default 500.html
. Is it possible/how to achieve that?
You can catch those exceptions and return a HttpResponse object to render your custom template. Or maybe a redirect is also appropriate.
Yes... and no.
You can render whatever you want (your web server has a nice explanation how to do that), but whether the user will see that is his choice - through his browser settings. It is possible you render something, but the browser still shows a standard error page.
A middleware might be a solution:
class MyExceptionMiddleware:
def process_exception(self, request, exception):
if isinstance(exception, CustomException):
template = loader.get_template('Other500.html')
context = RequestContext(request, {'message': 'Custom Message'})
return HttpResponseForbidden(template.render(context))
return None
Don't forget to register the middleware in settings.py:
MIDDLEWARE_CLASSES = (
....
'app.middleware.MyExceptionMiddleware',
