decorator to set attributes of function

Question

I want different functions to be executable only if the logged in user has the required permission level.

To make my life more complexly simply I want to use decorat

Answer 1

Your decorator should return a function that can replace do_x or do_y , not return the execution result of do_x or do_y You can modity you decorate as below:

def permission(permission_required):
    def wrapper(func):
        def inner():
            setattr(func, 'permission_required', permission_required)
            return func
        return inner()
    return wrapper

Of course, you have another brief solution:

def permission(permission_required):
    def wrapper(func):
        setattr(func, 'permission_required', permission_required)
        return func
    return wrapper
