I have been doing the Flask Web Development Book by Miguel Grinberg, and just finished up with the authorization blueprint. Though, I am having an issue that if I am already logged in, I can still put the url of the login page and go there. How can I prevent this in Flask?
While using Django, I came up with django-braces library which helps to do this, any such alternative available in Flask?
Redirect users who are logged in navigating to the login page.
To check if they are already logged in, examine the current_user proxy. Note that logged-in users will have current_user.is_authenticated() equal True, while users who aren't logged in will have the method return False.
You have two options for the destination: back to their previous page with redirect(request.referrer) or to one of your other pages with redirect(url_for('view_name')).
