Hello guys,
in the past few months I have been developing a simple web site using
Django. I found Django amazing and mature framework for my needs. I am
now about to publish it in public hosting.
To my dismay the erro info I have included in Http404 calls is wasted
by Django and cannot make it's way ot the handler404 and consequently
to the 404.html template.
Here is example code from my views.py:
#is user logged in
if not request.user.is_authenticated():
raise Http404(_("It is not allowed to post anonymous comments"))
Now I want to display the localized message in the 404.html but it
seems this does not make it to the handler404 view.
Here is what I found in the Django sources -
django.core.handlers.base.get_response:
except http.Http404, e:
logger.warning('Not Found: %s' % request.path,
extra={
'status_code': 404,
'request': request
})
if settings.DEBUG:
from django.views import debug
response = debug.technical_404_response(request,
e)
else:
try:
callback, param_dict = resolver.resolve404()
response = callback(request, **param_dict)
except:
As can be clealry seen the exception "e" is only passed ot the DEBUG
handler but no to the production one "callback".
My feature request is to add keyword argument param_dict "exception"
with the value of the Http404 exception "e" that is passed over to the
handler404 code. I can make this fix in my local deployment but it is
not possible to edit my hodting provider Django instance.
This will help communicate the details of the 404 errors to end users.
Same could be applied few lines below in the handler for
exceptions.PermissionDenied.
I hope this resonates with the development concepts of Django and this
small fix can make its way in to follow on release.
