Answer 1

You are defining a function , but you should define a class .

def PostListView(ListView):
    ...

# change to:

class PostListView(ListView):
    ...

Remember, that classes inherit another classes in their () , but functions recieve variables to use inside them. It is similar in some way, but very different in usage.
