Writing a To-Do client application

Let's do something interesting with the Odoo RPC API. We built a simple app for tasks we need to perform. What if users could manage personal tasks directly from their computer's desktop? We will create a command-line (CLI) client application that connects directly to our Odoo server and lets us manage our tasks.

We will split it into two files: one dealing with interactions with the server backend, todo_api.py, and another dealing with the application's user interface, todo.py.

Communication layer with Odoo

We will create a class to set up the connection with an Odoo server, and read/write To-Do tasks data. It should expose the basic CRUD methods:

• read() to retrieve task data
• write() to create or update tasks
• unlink() to delete a task

Select a directory to host the application files and create the todo_api.py file. We can start by adding the class constructor, as follows:

from xmlrpc import client
 
class TodoAPI(): 
    def __init__(self, srv, port, db, user...
