How can I implement role-based permissions in Flask-Security?

You can implement role-based permissions in Flask-Security by defining roles and associating them with users. Use the Role model to create roles and the User model to assign these roles to users.

Can you show me a code example for creating roles?

Sure! Here's a simple example:

from flask_security import Role, User, Security

class Role(db.Model, RoleMixin):
    id = db.Column(db.Integer(), primary_key=True)
    name = db.Column(db.String(length=80), unique=True)

class User(db.Model, UserMixin):
    id = db.Column(db.Integer(), primary_key=True)
    roles = db.relationship('Role', backref='users')

This defines a Role model and a User model with a many-to-many relationship.

How do I check if a user has a specific role?

You can check if a user has a specific role using the has_role method. For example:

if current_user.has_role('admin'):
    # grant access
