Writing a CherryPy Decorator for Authorization

Question

I have a cherrypy application and on some of the views I want to start only allowing certain users to view them, and sending anyone else to an authorization required page.

Answer 1

Ok, in that case your decorator would look something like this:

# without any parameters
def authentication_required(f):
    @functools.wraps(f)
    def _authentication_required(*args, **kwargs):
        # Do you login stuff here
        return f(*args, **kwargs)
    return _authentication_required

# With parameters
def authentication_required(*allowed_groups):
    def _authentication_required(f):
        @functools.wraps(f)
        def __authentication_required(*args, **kwargs):
            # Do you login stuff here
            return f(*args, **kwargs)
        return __authentication_required
    return _authentication_required
