/**
|
|
* A view class that is used for JSON responses.
|
|
*
|
|
* By setting the 'serialize' key in your controller, you can specify a view variable
|
|
* that should be serialized to JSON and used as the response for the request.
|
|
* This allows you to omit views + layouts, if your just need to emit a single view
|
|
* variable as the JSON response.
|
|
*
|
|
* In your controller, you could do the following:
|
|
*
|
|
* `$this->set(array('posts' => $posts, 'serialize' => 'posts'));`
|
|
*
|
|
* When the view is rendered, the `$posts` view variable will be serialized
|
|
* into JSON.
|
|
*
|
|
* If you don't use the `serialize` key, you will need a view + layout just like a
|
|
* normal view.
