How to get a Task's description inside runStep()?

Question

I know that I can get the default description of a Task with:

$this->description;
//or
$this->getDescription();

But how can I get the description if it got changed on creation:

craft()->tasks->createTask('Mailer', $new_description);

Adding it as an attribute doesn't seem "right" to me:

craft()->tasks->createTask('Mailer', $new_description, array('description' => $new_description));

Answer 1

The description you define in getDescription() is just the default description in the event that no description was specified when craft()->tasks->createTask() was called.

The actual description for the task is saved on the TaskModel, which you can get via $this->model from your Task class:

$description = $this->model->description;
