Hi Alberto,
I'm guessing `def blog(request):` is actually `blog_category_posts`, right?
Because you have `<slug>` on your URL, our view will receive it as another
parameter, after request. So it should be `def
blog_category_posts(requests, slug):` and then you can get the slug, filter
the posts and return them to the template.
