TypeError: ' class ' object is not callable flask api

I am trying to build an REST API using Flask with a MONGO DB , I faced this problem when I tried to use "flask_restplus"

that's the error : 

[2018-03-16 15:22:12,854] ERROR in app: Exception on /bill [GET]
Traceback (most recent call last):
  File "/home/heythem/PycharmProjects/webAPI/venv/lib/python3.5/site-packages/flask/app.py", line 1982, in wsgi_app

    app_rv = app(environ, start_response)
TypeError: 'Bill' object is not callable

 

@app.route('/bill')
class Bill(Resource):
    def get(self):
        bill = mongo.db.bill

        output = []
        for q in bill.find():
            output.append({
                'monitor_id': q['monitor_id'],
                'Bill_id': q['Bill_id'],
                'Amount': q['Amount']

            })
        print(output)
        return json_util.dumps({'result': output})

when I tried to test it as flask-restful API with : 

api = Api(app)

I started to get that error

There are two objects, app and api

The subtle difference here is to use @api.route() not @app.route()

The routes should be defined on the flask_restplus's Api not flask's Flask for this to work.

Instead of decorating your class with @app.route(), use @api.resource()
