How do I write a decorator for my Django/Python view?

Question

Here\'s my view. Basically, it returns different Responses based on whether it\'s logged in or not.

@check_login()
def home(request):
    if is_logged_in(req

A plain decorator is simply a function that takes a function or class and returns something else (usually the same type, but this is not required). A parametrized decorator is a function that returns a decorator.

So, with that in mind we create a closure and return it:

def check_login(func):
  def inner(request, *args, **kwargs):
    if request.META['username'] == 'blah':
      login(request, user) # I have no idea where user comes from
    func(request, *args, **kwargs)
  return inner
