This is the fifth installment of the Flask Mega-Tutorial series, in which I'm going to tell you how to create a user login subsystem. For your reference, below is a list of the articles in this series.
Flask-Security uses internally a User and Role data model, that could be defined via the SQL Alchemy API. The User class derives from the UserMixin Flask-Login default user implementation and same goes for the Role class â RoleMixin.

The @login_manager.user_loader piece tells Flask-login how to load users given an id. I put this function in the file with all my routes defined, as thatâs where itâs used. The /reports Endpoint. Now, I could create a /reports endpoint that required authentication. Hereâs what the code for that endpoint looks like:
Dec 13, 2017 Â· Flask-Security's authentication mechanism (through Flask-Login) controls the return value of current_user.is_authenticated().Returning this (possibly combined with some kind of role / permission checking) in your is_accessible implementation should give you the ability to use Flask-Security's protection within Flask-Admin. â jonafato Jun 27 '15 at 22:45
