As we said in the previous recipe, when you add a directory to the addons path, just restarting the Odoo server is not enough to be able to install one of the new addon modules. A specific action is required for Odoo to scan the addons path and update the list of available addon modules.
Start your instance, and connect to the instance using the Administrator account and activate the developer mode (see Chapter 1, Installing the Odoo Development Environment).
To update the list of available addon modules in your instance, you need to perform the following steps:
When the Update button is clicked on, Odoo will read the addons path configuration variable, and for each directory in the list, it will look for immediate subdirectories containing an addon
manifest file, which is a file named __openerp__.py, stored in the addon module directory. Odoo reads the manifest expecting to find a Python dictionary. Unless the manifest contains a key installable set to False, the addon module metadata is recorded in the database. If the module was already present, the information is updated; otherwise, a new record is created. If a previously available addon module is not found, the record is not deleted from the list.
