Instead of using @login_required decorator, use @method_decorator(login_required) on your post method, like so:

from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator

class HomeView(TemplateView):
    # ...
    @method_decorator(login_required)
    def post(self, request):
        # ...

The reason why you're seeing an error message is because login_required is a function decorator - so it expects the request object to be the first argument passed to your view. Your post definition is a method, therefore self (HomeView) is the first argument that's getting passed, and this is what login_required tries to use as a Request instance.

method_decorator is used to transform every function decorator to a method decorator. See the docs for more info.
