Looks like you probably need to escape (double) the % signs: https://docs.djangoproject.com/en/1.5/ref/class-based-views/base/#django.views.generic.base.RedirectView > The given URL may contain dictionary-style string formatting, which > will be interpolated against the parameters captured in the URL.

But really, while I might somewhat see the point of using TemplateView[0] I don't see the point of using RedirectView in that manner, why not just return an HttpResponseRedirect[3]? Class-based views are really for using in URL mappings (potentially custom subclasses), not for using in your own view functions. [0] Still, it would probably be simpler to use TemplateResponse[1] directly, or render_to render_to_response[2] if it's sufficient [1] https://docs.djangoproject.com/en/dev/ref/template-response/#templateresponse-objects [2] https://docs.djangoproject.com/en/dev/topics/http/shortcuts/#django.shortcuts.render_to_response [3] https://docs.djangoproject.com/en/dev/ref/request-response/#django.http.HttpResponseRedirect -- You received this message because you are subscribed to the Google Groups "Django users" group.
