I have an app, which is quite big, so it's divided into modules and use blueprints, add_url_rule for routing to various modules. Everything works fine and as intented.
The problem is, I need to use the Flask-Login (https://flask-login.readthedocs.org/en/latest/#api-documentation), from the documentaion. I could only find how to protect views using decorators, for which the app should have routes set using the app.route('/home'). But like I already mentioned, I'm using blueprints and add_url_rule.
EDIT: The answer @Mark Hildreth edited into this question, is the required solution. Thank you.
