Building RESTful services with Flask-RESTful

The flask-RESTful module uses the class-based view strategy of Flask to build RESTful services. It provides a Resource class to create custom resources to build from the ground up HTTP-based services instead of endpoint-based routes.

This chapter specifies another application, ch04-api, that implements RESTful endpoints for managing user complaints and related details. Here’s one of the resource-based implementations of our application’s API endpoints:

from flask_restful import Resource
class ListComplaintRestAPI(Resource):
    def get(self):
        repo = ComplaintRepository(db_session)
        records = repo.select_all()
        complaint_rec = [rec.to_json() for rec in records]
        return make_response(jsonify(complaint_rec), 201)
