We will often want to use custom or community modules with our Odoo instance. Keeping them in a separate directory makes it easier to install upgrades to Odoo or troubleshoot issues from our custom modules. We just have to add that directory to the addons path and they will be available in our instance, just like the core modules are.
It is possible to think about this module directory as an Odoo environment. The Odoo start command makes it easy to organize Odoo instances as directories, each with its own modules.
For this recipe we need to have already installed Odoo. We assume that it will be at ~/odoo-dev/odoo, and that the virtualenv is activated.
This means that the following command should successfully start an Odoo server:
$ ~/odoo-dev/odoo/odoo.py
To create a work environment for your instance, you need to follow these steps:
Change to the directory where Odoo is:
$ cd ~/odoo-devChoose a name for the environment and create a directory for it:
$ mkdir my-odooChange to that directory and start an Odoo server instance for that environment:
$ cd my-odoo/ $ ../odoo/odoo.py start
The Odoo start command is a shortcut to start a server instance using the current directory. The directory name is automatically used as the database name (for the -d option), and the current directory is automatically added to the addons path (the --addons-path option) as long as it contains an Odoo addon module. In the preceding recipe you won't see the current directory in the addons path because it doesn't contain any modules yet.
By default the current directory is used, but the --path option allows you to set a specific path to use instead. For example, this would work from any directory:
$ ~/odoo-dev/odoo/odoo.py start --path=~/odoo-dev/my-odoo
The database to use can also be overridden using the usual -d option. In fact, all the other usual odoo.py command-line arguments, except --addons-path, will work. For example, to set the server listening port, use the following command:
$ ../odoo/odoo.py start --xmlrpc-port=8080
As we can see, the Odoo start command can be a convenient way to quickstart Odoo instances with their own module directory.
