.hide(code) ⇒ Object

These methods provide a mechanism for plugins to hide (or show) permissions that are not relevant due to customizations made by the plugin. This is done by setting the :system attribute to true. System permissions behave exactly like other permissions except they are hidden from the user. NOTE: the update is done via a direct database query rather than via the model because the permission table does not have a :lock_version column, so the optimistic_locking plugin freaks out on Permission.update
