What are Flask-Security roles and how do I implement them?

Flask-Security roles are a way to manage user permissions in a Flask application. You can implement them by defining roles in your user model and using decorators to restrict access to certain views.

Can you give me an example of how to define roles in my user model?

Sure! You can define roles in your user model like this:

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True)
    roles = db.relationship('Role', secondary='user_roles')

And then create a Role model to represent different roles.

How do I restrict access to a view based on roles?

You can use the @roles_required decorator provided by Flask-Security. For example:

@app.route('/admin')
@roles_required('admin')
def admin_view():
    return 'Welcome to the admin panel!'

What if I want to allow multiple roles to access a view?

You can pass a list of roles to the @roles_required decorator like this:

@app.route('/dashboard')
@roles_required('admin', 'editor')
def dashboard_view():
    return 'Welcome to the dashboard!'
