Creating/updating/deleting records through 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 library.book model. Make sure you have installed the my_library module and that the server is running on http://localhost:8069.

How to do it...

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

1. Add the jsonrpc_operation.py file. You can place this file anywhere you want because the RPC program will work independently.
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 books records
       create_data = [
