How can I implement permissions in a Flask-RESTful API?

You can use Flask-RESTful along with Flask-Security or Flask-JWT to manage permissions. Would you like a code example?

Yes, please provide a code example for using Flask-JWT.

Sure! First, install Flask-JWT. Then, you can create a decorator to check permissions like this:

from flask_jwt import jwt_required, current_identity

def permission_required(permission):
    def wrapper(fn):
        @jwt_required()
        def decorated(*args, **kwargs):
            if permission not in current_identity.permissions:
                return {'message': 'Permission denied'}, 403
            return fn(*args, **kwargs)
        return decorated
    return wrapper

How do I assign permissions to users?

You can assign permissions by adding a 'permissions' field to your user model and updating it when creating or modifying users.
