cakephp分页功能，paginate联表查询

PHP部分：

function praise_detail($main_id){
$joins = array(array(
‘table’ => ‘comment_praises’,
‘alias’ => ‘CommentPraise’,        
‘type’ => ‘INNER’,        
‘conditions’ => array(‘CommentPraise.comment_task_id = CommentTask.id’)
));
$fields = array(‘CommentPraise.*’,’CommentTask.*’);

$this->paginate = array(‘fields’=>$fields,’conditions’=>array(‘CommentPraise.main_task_id’=>$main_id),’joins’=>$joins,’order’=>’CommentPraise.id ‘,’limit’=>50);
// var_dump(‘praise_detail’);var_dump($this->paginate());
$this->set(‘tasks’, $this->paginate());

}
