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 user roles.

Sure! Here's a simple example:

from flask import Flask, request
from flask_restful import Resource, Api
from flask_security import Security, SQLAlchemyUserDatastore, UserMixin, RoleMixin

# Define your User and Role models
class Role(db.Model, RoleMixin):
    pass

class User(db.Model, UserMixin):
    pass

# Setup Flask-Security
user_datastore = SQLAlchemyUserDatastore(db, User, Role)
security = Security(app, user_datastore)

class ProtectedResource(Resource):
    @auth.login_required
    def get(self):
        return {'message': 'This is a protected resource.'}

api.add_resource(ProtectedResource, '/protected')

How do I set up user roles in the database?

You can create roles in your database using the user_datastore.create_role() method. Would you like to see how to do that?
