How can I implement user roles in a Flask application?

You can implement user roles in Flask by using Flask-Login for authentication and Flask-SQLAlchemy for database management.

Can you give me a code example for defining roles?

Sure! You can define roles in your User model like this: roles = db.Column(db.String(80)) and then assign roles to users.

How do I check a user's role in a route?

You can use a decorator to check roles. For example, @login_required and then check current_user.roles in your route.

What if I want to restrict access to certain views based on roles?

You can create a custom decorator that checks the user's role before allowing access to those views.
