How To Use Flask Login With Blueprints

I'm trying to use LoginManager for my flask application. When I run the application and open the index page, it says the following File '...\python38-32\lib\site-packages\flask\app

Solution 1:

You can try to search same problem UndefinedError: 'current_user' is undefined

Check the init file:

login_manager = LoginManager()
    login_manager.login_view = 'auth.login'
    login_manager.init_app(app)
    from .models import User
    @login_manager.user_loader
    def load_user(user_id):
        user = User.query.filter_by(id=user_id).first()

And strure, i think you should do like that
