Calling methods using JSON-RPC

In this recipe, we will learn how to invoke a custom method of the model through JSON-RPC. We will change the status of the room by calling the make_available() method.

Getting ready

We will create the Python program to call make_available on the hostel.room model. Make sure you have installed the my_hostel module and that the server is running on http://localhost:8017.

How to do it...

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

1. Add the jsonrpc_method.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:
    # Create the room record in draft state
    payload = get_json_payload("object", "execute_kw",
