from flask import jsonify, Blueprint

from flask_restful import (Resource, Api, reqparse, inputs, fields, marshal, marshal_with)

import models

course_fields = { 'id': fields.Integer, 'title': fields.String, 'url': fields.String, 'reviews': fields.List(fields.String) }

class CourseList(Resource): def init(self): self.reqparse = reqparse.RequestParser() self.reqparse.add_argument( 'title', required=True, help='No course title provided', location=['json', 'form'] ) self.reqparse.add_argument( 'url', required=True, help='No course URL provided', location=['json', 'form'], type=inputs.url ) super().init()

def get(self):
    courses = [marshal(course, course_fields)
               for course in models.Course.select()]
    return {'courses': courses}

def post(self):
    args = self.reqparse.parse_args()
    models.Course.create(**args)
    return jsonify({'courses': [{'title': 'Python Basics'}]})

class Course(Resource): def get(self, id): return jsonify({'title': 'Python Basics'})

def put(self, id):
    return jsonify({'title': 'Python Basics'})

def delete(self, id):
    return jsonify({'title': 'Python Basics'})

courses_api = Blueprint('courses', name) api = Api(courses_api) api.add_resource( CourseList, '/api/v1/courses', endpoint='courses' ) api.add_resource( Course, '/api/v1/courses/<int:id>', endpoint='course' )
