How does user_loader works in Flask-Login > 0.4.1

[saromba]

When I update my project from Flask-Login 0.4.1 to 0.5.0 (or latest), the 'user_loader' decorator is no more working.
When later calling @roles_required('Read') I get always an Unauthorized Access...

in the app.py
...
user_manager = ApiUserManager(app.app, db, ApiUser, auth_object)
login_manager = user_manager.login_manager


@login_manager.user_loader
def load_user(user_id):
    try:
        return ApiUser.query.filter(ApiUser.id == user_id).first()
    except:
        return None

How does this work at the moment?

It continues to work as shown. You can refer to the docs for examples if you're unsure. It sounds like you have an unrelated error in your code, and have incorrectly identified Flask-Login as the cause. You might try taking out the bare except block to start debugging, as that's an antipattern in Python in general.

Ok thanks for your quick reply... I'm still trying to find my error.
Could it be that the user_id in the flask session has changed from "user_id" to "_user_id" ?
