CakePHP 分页最大限制不起作用

Question

我正在使用 cakephp 2.x。我无法设置记录的最大限制。

请检查我的代码：

App::uses('AppController', 'Controller');
class BroadcastsController extends AppController {
   public $components = array('Paginator');

   public function broadcast(){           
         $this->Paginator->settings = array('limit' => 10,  'order' => array('Broadcast.no_of_user' => 'DESC'), 'group' => 'Broadcast.broadcaster_id');
         $popularRooms = $this->Paginator->paginate('Broadcast');
         pr($popularRooms); //fetch 200 records
         $this->set('popularRooms', $popularRooms);
   }
}

以上 pr($popularRooms); 我得到 200 条记录，但我想要前 50 条记录，并且每页显示 10 条记录。我使用的是 'maxLimit'=>50，但此代码与 'limit'=>50 相同。请帮助我。

Answer 1

public function list_posts() {
    $settings = array(
       'limit' => 25, // here
       'order' => array(
          'Post.title' => 'asc'
        )
    );
    $this->Paginator->settings = $this->settings;
    // similar to findAll(), but fetches paged results
    $data = $this->Paginator->paginate('Posts');
    $this->set('data', $data);

}

Answer 2

我相信你不必有 $this->Paginator->settings =.

public function list_posts() {
$settings = array(
   'limit' => 25, // here
   'order' => array(
      'Post.title' => 'asc'
    )
);
// similar to findAll(), but fetches paged results
$data = $this->Paginator->paginate('Posts');
$this->set('data', $data);

Answer 3

在限制之前首先在分页器设置中设置 maxLimit，如下所示：

$this->Paginator->settings = array(
 'maxLimit' => 50,  
 'limit' => 10,  
 'order' => array('Broadcast.no_of_user' => 'DESC'), 
 'group' => 'Broadcast.broadcaster_id'
);

仅在逻辑上设置其中之一不会改变任何内容。

Answer 4

在这种情况下，您可以在分页器设置中使用 'extras' 数组

$this->Paginator->settings = array('limit' => 10, 'max_record'=>50, 'order' => array('Broadcast.no_of_user' => 'DESC'), 'group' => 'Broadcast.broadcaster_id');

在您的模型或 AppModel 中覆盖 paginateCount 函数

class Broadcast extends AppModel { 
function paginateCount($conditions, $recursive, $extra) {
    $param = array_merge(compact('conditions', 'recursive'), $extra);
    $count = $this->find('count', $param);
    if (!empty($extra['max_record']) && $count > $extra['max_records']) {
      $count = $extra['max_record'];
    }
    return $count;
  } 
}

Answer 5

默认情况下，CakePHP 将可以获取的最大行数限制为 100.You 可以将其作为分页选项的一部分进行调整，如下所示

public $paginate = array(
    // other keys here.
    'maxLimit' => 10
);

对于你的代码，像这样设置 maxLimit

 $this->Paginator->settings = array('limit' => 10,'maxLimit'=>50,'order' => array('Broadcast.no_of_user' => 'DESC'), 'group' => 'Broadcast.broadcaster_id');
