使用Django的RedirectView和一个命名的url

Question

I'm trying to make my a_detail redirect to my a_detail_slug url. I want to use the named url for this but I haven't succeeded yet, this is what I've tried:

url(r'^a/(?P<pk>\d+)/(?P<filler>[\w-]+)/$', AList.as_view(template_name="a.html"), name="a_detail_slug"),

url(r'^a/(?P<pk>\d+)/$', RedirectView.as_view(url=reverse_lazy("a_detail_slug"),), name="a_detail"),

This is meant to catch any link with a valid pk and redirect to that page with an appended filler.

Answer 1

a_detail_slug requires 2 params ( pk and filler ) but you pass none of them. The easiest way will be extend RedirectView:

class ARedirect(RedirectView):
    def get_redirect_url(self, pk):
        filler = get_filler_somehow()
        return reverse('a_detail_slug', args=(pk, filler))
