-------------------------------+--------------------
When using TemplateView for handler403, an unhandled error occurs:
{{{
from django.conf.urls import url
from django.core.exceptions import PermissionDenied
from django.views.generic import TemplateView
class PermissionDeniedView(TemplateView):
template_name = '403.html'
handler403 = PermissionDeniedView.as_view()
def my_view(request):
raise PermissionDenied
urlpatterns = [
url(r'^$', my_view),
]
}}}
Traceback:
{{{

}}}
One workaround is to force TemplateResponse to render itself:
{{{
class PermissionDeniedView(TemplateView):
template_name = '403.html'
def dispatch(self, request, *args, **kwargs):
response = super(PermissionDeniedView, self).dispatch(request,
*args, **kwargs)
response.render()
return response
}}}
