Redirect from Generic View DetailView in Django

Question

I\'m using Django\'s class based DetailView generic view to look up an object for display. Under certain circumstances, rather than displaying the object, I wish to back ou

This isn't a natural fit for DetailView. To do this you need to override the get method of BaseDetailView, which looks like:

class BaseDetailView(SingleObjectMixin, View):
    def get(self, request, **kwargs):
        self.object = self.get_object()
        context = self.get_context_data(object=self.object)
        return self.render_to_response(context)

So in your class you'd need to provide a new get method which did the URL check between fetching the object and setting up the context. Something like:

def get(self, request, **kwargs):
    self.object = self.get_object()
    if self.request.path != self.object.get_absolute_url():
        return HttpResponseRedirect(self.object.get_absolute_url())
    else:
        context = self.get_context_data(object=self.object)
        return self.render_to_response(context)

As you end up overriding so much of the functionality it becomes questionable whether it's worth actually using a generic view for this, but youknow.
