Cakephp containable behavior

Containable behavior is useful in providing customized model linking when using model find function to retrieve db data. Compared to using 'recursive' attribute, containable is more customized cuz it allows programmers to choose which models they want to link to.

 

e.g.

 

1. use containable behavior

 

 

class Post extends AppModel { var $actsAs = array('Containable');}

2. set contained model

 

$this->Post->contain('Tag');$this->Post->find('all');// or $this->Post->find('all', array('contain' => 'Tag'));
