actions_synchronize($actions_in_code = array(), $delete_orphans = FALSE)

Синхронизировать действия которые переданы из модуля

They are synchronized with actions that are stored in the actions table. This is necessary so that actions that do not require configuration can receive action IDs. This is not necessarily the best approach, but it is the most straightforward.
