# Actions' attributes
In order to unify the various forms an action can take, the data of an action is implemented as a set of attributes (similarly to models).
This means when interacting with an instance of an Action, you can manipulate its attributes with the following methods:
$action = new Action(['key' => 'value']); // Initialise an action with the provided attribute.
$action->fill(['key' => 'value']); // Merge the new attributes with the existing attributes.
$action->all(); // Retrieve all attributes of an action as an array.
$action->only('title', 'body'); // Retrieve only the attributes provided.
$action->except('body'); // Retrieve all attributes excepts the one provided.
$action->has('title'); // Whether the action has the provided attribute.
$action->get('title'); // Get an attribute.
$action->get('title', 'Untitled'); // Get an attribute with default value.
$action->set('title', 'My blog post'); // Set an attribute.
$action->title; // Get an attribute.
$action->title = 'My blog post'; // Set an attribute.
Depending on how an action is ran, its attributes are filled with the relevant information available. For example, as a controller, an action’s attributes will contain all of the input from the request. For more information see:
