Transforming Function Based View To Class Based View

I think it should be simpler but here's my function based view with filter def withSub(request): post = Post.objects.filter(with_or_without_sub='WS') paginator = Paginator(

Solution 1:

It could be something like the follows. You might need to test and debug. The request.GET is used, so it's get.

from django.views.generic.listimport ListView

classPostListView(ListView):
    model = Post
    template_name = 'community/home.html'# <app>/<model>_<viewtype>.htmldefget(self, request, *args, **kwargs):
        post = Post.objects.filter(with_or_without_sub='WS')
        paginator = Paginator(post, 2)
        page = request.GET.get('page') 
        post = paginator.get_page(page)

        content_dict = {
            'posts':post,
            'paginator':paginator

        }

        context = self.get_context_data()
        context.update(content_dict)
        return self.render_to_response(context)

Solution 2:

If you want to customise the queryset, use the queryset attribute:

classPostListView(ListView):
    queryset = Post.objects.filter(with_or_without_sub='WS')
    template_name = 'community/home.html'

Solution 3:

You get either set a specific queryset, like this:

queryset = Post.objects.filter(with_or_without_sub='WS')

or if there's more complex logic eventually involved, you can override the get_queryset() method of the view, like this:

from django.views.generic.listimport ListView

classPostListView(ListView):
    model = Post
    template_name = 'community/home.html'defget_queryset(self):
        return Post.objects.filter(with_or_without_sub='WS', ...)
