Creating/updating/deleting records using JSON-RPC

In the previous recipe, we looked at how to search and read data through JSON-RPC. In this recipe, we will perform the remaining CRUD operations through RPC: create, update (write), and delete (unlink).

Getting ready

We will create a Python program to create, write, and unlink data in the hostel.room model. Make sure you have installed the my_hostel module and that the server is running on http://localhost:8017.

Perform the following steps to create, write, and unlink a room’s information through RPC:

2. Add the following code to the file:

   # place authentication and get_json_payload method (see last recipe for more)
   if user_id:
       # creates the room's records
       create_data = [
