I am using a ListView that list videos according to tags. The filtering happens in get_queryset(). I'd like to redirect the user to another page if the tag doesn't contains any video.
With a function, it would be easy. Query, check the queryset, redirect. With a class, I fail doing so:
class VideosView(generic.ListView):
def get_queryset(self):
"""
This work.
"""
tag = self.kwargs.get('tag', None)
self.videos = Video.on_site.all()
if tag:
self.videos = Video.tagged.with_all(tag, self.videos)
return self.videos
def get(self, request, *args, **kwargs):
"""
This doesn't work because self.videos doesn't exist yet.
"""
if not self.videos:
return redirect('other_page')
return super(Videos, self).get(request, *args, **kwargs)
