membuat kondisi di cakephp 2

membuat suatu kondisi where di cakephp yaitu dengan cara di controller misalnya contoh seperti ini
:

public function penonton() {

  $penontons = $this -> Tiket -> find('all', array('conditions' => array('Tiket.status' => 'lunas')));

//                print_r($penontons);

  $this -> set('tiket', $this -> paginate());

  $this -> set(compact('penontons'));

  //                        print_r($users);



 }

$this->Post->find('all', 
                   array('conditions'=>array('User.id'=>1, 
                                             'Post.id'=>'> 50')));

# TODO - i'm not sure that this is right; i think 'fields' is supposed to be an array
$this->Post->find('all',
                  array('conditions'=>array('User.id'=>5),
                        'fields'=>'Post.name',
                        'order'=>'Post.id ASC',
                        'limit'=>20,
                        'recursive'=>0));

$posts = $this->Post('all', array( 'conditions' => array('OR' => array('Post.status' => 1, 'Post.type' => 2) )  ) );
'conditions' => array('Post.id >' => 20 ,'OR' => array('Post.status' => 1, 'Post.type' => 2) )
$posts = $this->Post('all', array( 'conditions' => array('OR' => array(array( 'Post.status' => 1), array( 'Post.status' => 2) ) )  ) );
