Server actions underpin the Odoo automation tools. They allow us to describe the actions to perform. These actions are then available to be called by event triggers, or to be triggered automatically when certain time conditions are met.

The simplest case is to let the end user perform some action on a document by selecting it from the More button menu. We will create such an action for project tasks, to Set as Priority by starring the currently selected task and setting a deadline on it to 3 days from now.
