Question

我正在尝试在Cake中使用自定义查询，然后使用以下代码对结果进行分页：

$query = $this->Petition->query($sql);

我试过了：

$petitions = $this->paginate($query);

它不起作用。我们有办法做到这一点吗？

好吧我还不够清楚：我需要在分页时使用从自定义查询中获取的变量数组，这样我就可以在视图中使用它进行分页。有这么简单的方法吗？以下是我的代码：

function index() {
        if ($this->Session->read('Auth.User.group_id') != 1) {
            $commune_id = $this->Session->read('Auth.User.commune_id');
            $commune_id = $this->Petition->Commune->findbyId($commune_id);
            $commune_id = $this->Petition->Commune->find('all',array('conditions' => array('group' => $commune_id['Commune']['group'])));
            $count = count($commune_id);
            $i=1;
            $sql = "SELECT * FROM `petitions` WHERE `commune_id` = ";
            foreach($commune_id as $commune_ids){
                if($i==1){
                $sql .= $commune_ids['Commune']['id'];
                }else{
                $sql .= " OR `commune_id` = ".$commune_ids['Commune']['id'];
                }
            /*if($i != $count){
            $this->paginate = array(
                'or' => array(
                    array('Petition.commune_id LIKE' => $commune_ids['Commune']['id'] . ","),
                    //array('Petition.commune_id LIKE' => "," . $commune_ids['Commune']['id'] . ",")
                    ),
                'limit' => 10
            );
            }*/
            $i++;
            }
            $query = $this->Petition->query($sql);
        }
        $this->Petition->recursive = 0;
        $petitions = $this->paginate();
        $this->set('petitions', $petitions);
    }

Answer 1

这不是分页的工作原理你需要填写$ this-＆gt;验证您的条件等然后明白地使用$ this-＆gt; paginate（）

见 http://book.cakephp.org/view/1232/Controller-Setup

还要注意有关自定义查询部分的章节，如果它真的是（！）必要的话。

你真的需要阅读蛋糕书中的分页部分：

function index() {
    $conditions = array();
    if ($this->Auth->user('group_id') != 1) {
        $commune_id = $this->Petition->Commune->findById($this->Auth->user('commune_id'));
       $conditions['Petition.id'] = $this->Petition->Commune->find('list',array(
            'fields'=>array('id','id')
            'conditions' => array('group' => $commune_id['Commune']['group'])
        ));
    }
    $this->Petition->recursive = 0;
    $petitions = $this->paginate('Petition',$conditions);
    $this->set('petitions', $petitions);
}

类似的东西。
