Calling methods through 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 book's state.

Getting ready

We will create the Python program to call make_available on the library.book model. Make sure that 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 update a book's information through RPC:

1. Add the books_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:8069'
   db_name = 'book-db-14'
   username = 'admin'
   password = 'admin'
   
common = client.ServerProxy('%s/xmlrpc/2/common' % 
       server_url...
