Run an Odoo REPL / IPython prompt

One of the most useful things in Odoo

$ ./odoo-bin shell \
    -c /etc/odoo.conf \
    --xmlrpc-port=8888 \
    --longpolling-port=8899 \
    -d odoo
        

In Odoo, you have the ability to run Odoo as a web server and access it via a GUI, but you can also run a python REPL with all of the Odoo modules loaded in as globals. This is extremely helpful for debugging and for learning.

For example, you could start up the shell, query for information via env/search/browse commands, run individual functions, access variables and properties associated with core classes, load in new functions if needed for testing, etc.

How to run an Odoo shell

Let’s break down the command:


$ ./odoo-bin shell \
    -c /etc/odoo.conf \
    --xmlrpc-port=8888 \
    --longpolling-port=8899 \
    -d odoo
        

./odoo-bin shell

odoo-bin is the executable in the root directory of the core Odoo project. This is how you run an Odoo instance.

If you run odoo-bin help you will see that we have a few different commands that we can run. One of those commands is shell which will start up our REPL.


odoo:$ ./odoo-bin help
Available commands:

    deploy    Deploy a module on an Odoo instance
    help      Display the list of available commands
    scaffold  Generates an Odoo module skeleton
    server    Start the odoo server (default command)
    shell     Start odoo in an interactive shell
    start     Quick start the Odoo server for your project

Use 'odoo-bin <command> --help' for individual command help
        

-c /etc/odoo.conf

Reference to your configuration files, if relevant. If you do not need all of your configurations and addons referenced then you can leave this off.

--xmlrpc-port=8888 --longpolling-port=8899

More optional flags. I use these because then I can run a standard Odoo instance on 8069/8072, but run a shell prompt at the same time on separate non-conflicting ports. You can use any open ports that you would like.

-d odoo

The database that you want to connect to. All Odoo shell prompts are connected to a single database at a time.

What do you have reference to?

Once you got a shell prompt up and running, then check out what you actually have reference to. You can see this by runnng globals():

Here are some of the globals that I end up using the most often:

self


In [1]: self
Out[1]: res.users(1,)
        

self is a reference to the currently logged in user. By default, this is going to be id=1 (the admin user.)

env

A global reference to the Environment similar to if you would access it via self.env .

This is where we can start querying/accessing different data in the system:


In [1]: attachments = env["ir.attachment"].search([])

In [2]: attachments
Out[2]: ir.attachment(356, 355, 354, 353, 352)
        

odoo / openerp

The global reference to the odoo core. Anything that you would typically import in modules is accessible. So if you need to access odoo.models , odoo.tools , odoo.exceptions , etc. you can import or reference those in the shell prompt.


In [1]: f = odoo.fields.Many2one

In [2]: dir(f)
Out[12]:
['__class__',
 '__delattr__',
 '__dir__',
 '__doc__',
 '__eq__',

... ]
        

Some Tricks

Here are just a couple of quick tricks that I use pretty often within the odoo shell.

General Imports

Just like any ipython prompt, you can import any accessible library. This is extremely helpful as you start debugging. Bring different libraries into the prompt.


In [1]: import math, string, io
        

Viewing Properties and Functions

At the beginning of this article, I said that the shell is great for both debugging and learning. Seeing the properties and functions available helped me initially learn how Odoo worked internally.

You can go through everything available to you via the global odoo or env module.

Let’s take the search method for example. This is something that many odoo developers use via commands like env['my.model'].search . But we can see a quick description of this directly in the prompt by using ?? :

Above, we are assuming that we already know that the search method exists. If we actually need to find methods then we can hit tab at the end of a variable to see all available properties and methods:

Committing Data

Be careful with this since it actually writes to your database.

If you need to update some record via the odoo shell, you have to run the update method like you would in a standard custom module, but then you have to manually commit them to the database via env.cr.commit.


In [1]: users = env["res.users"].search([])

In [2]: for user in users:
   ...:     user.update({"create_uid": 1})
   ...:

In [3]: env.cr.commit()
