How to use django custom decorator

Question

I have a lot of methods that require authorization. So instead of writting the same code over and over I wanna simplify it. As I understood I can't use @login_required as it redirects to login page, which I don't have. (user logs in into system via dropdown menu included in all templates). I just wanna raise PermissionDenied without any redirecting.

get_profile(request):
    if request.user.is_authenticated():
       do things
    else:
       raise PermisionDenied

One solution is use a custom decorator:

def login_required_no_redirect(f):
    def wrap(request, *args, **kwargs):
        if request.user.is_authenticated():
            return f(request, *args, **kwargs)
        else:
            raise PermissionDenied

    wrap.__doc__ = f.__doc__
    wrap.__name__ = f.__name__
    return wrap

But it requires to pass a function inside. So I can't just place @login_required_no_redirect() above the method. It requires to pass some function as a parameter. Where do I get it? There're a lot of django decorators without parameters, how do I write the similar one?

Best regards,

Django already has a @permission_required decorator for this.

If the raise_exception parameter is given, the decorator will raise PermissionDenied, prompting the 403 (HTTP Forbidden) view instead of redirecting to the login page.
