You can alias your task as an existing task by setting the 'className' key, i.e.,
{{{
public $tasks = array(
'DbConfig' => array(
'className' => 'Bakeplus.DbConfigure'
);
);
}}}

trigger() public ¶
trigger( string|CakeEvent $callback , array $params = array() , array $options = array() )
Trigger a callback method on every object in the collection. Used to trigger methods on objects in the collection. Will fire the methods in the order they were attached.
Options
breakOnSet to the value or values you want the callback propagation to stop on. Can either be a scalar value, or an array of values to break on. Defaults tofalse.breakSet to true to enabled breaking. When a trigger is broken, the last returned value will be returned. If used in combination withcollectReturnthe collected results will be returned. Defaults tofalse.collectReturnSet to true to collect the return of each object into an array. This array of return values will be returned from the trigger() call. Defaults tofalse.modParamsAllows each object the callback gets called on to modify the parameters to the next object. Setting modParams to an integer value will allow you to modify the parameter with that index. Any non-null value will modify the parameter index indicated. Defaults to false.
Parameters
-
string|
CakeEvent$callback Method to fire on all the objects. Its assumed all the objects implement the method you are calling. If an instance of CakeEvent is provided, then then Event name will parsed to get the callback name. This is done by getting the last word after any dot in the event name (eg.
Model.afterSaveevent will trigger theafterSavecallback)- array $params optional array()
- Array of parameters for the triggered callback.
- array $options optional array()
- Array of options.
