Flask Tutorial Web Development with Python 20 - Login Required Decorator Wrapper

Welcome to part 20 of our Flask web development tutorial, in this video we discuss how to use various decorator wrappers. The example used here is for a login_required wrapper, which requires a user to be logged in to view the page. If they are not logged in, then it notifies them and sends them to the login page.

You can use these wrapper functions, however, to protect pages for subscribers, admins, and other various user requirements.
