Calling methods using XML-RPC

With Odoo, the RPC API is not limited to CRUD operations; you can also invoke business methods. In this recipe, we will call the make_available method to change the room’s state.

Getting ready

We will create the Python program to call make_available on the hostel.room model. Make sure that 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 rooms_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:

   from xmlrpc import client
   server_url = 'http://localhost:8017'
   db_name = 'cookbook_17e'
   username = 'admin'
   password = 'admin'
   common = client.ServerProxy('%s/xmlrpc/2/common' % server_url)
   user_id = common.authenticate(db_name...
