如何限制cakephp中的分页符

function listRecords()
  {
  $this->paginate = array(
    \'conditions\' => array(\'Model.id >=\' => 50, \'Model.id <=\' => 75),
    \'limit\' => 5
    );
  $this->paginate(\'Model\');
  );

$this->paginate = array(
  \'limit\' => 20,
  \'totallimit\' => 1000
  );

public function paginateCount($conditions = null, $recursive = 0, $extra = array())
  {
  if( isset($extra[\'totallimit\']) ) return $extra[\'totallimit\'];
  }

public function paginateCount($conditions = null, $recursive = 0, $extra = array()) 
    {
        $conditions = compact(\'conditions\');
        if ($recursive != $this->recursive) {
            $conditions[\'recursive\'] = $recursive;
        }
        unset( $extra[\'contain\'] );
        $count = $this->find(\'count\', array_merge($conditions, $extra));

        if (isset($extra[\'group\'])) {
            $count = $this->getAffectedRows();
        }

        if (isset($extra[\'totallimit\']) && $extra[\'totallimit\'] < $count) {
            return $extra[\'totallimit\'];
        }

        return $count;
    }

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

$query = $this->User->find(\'all\', [
    \'recursive\' => 2,
    \'order\' => array(\'Profile.winning\' => \'DESC\'),
    \'limit\' => 25, 
    \'offset\' => 50
]);
$this->paginate = array(
    $query,
    \'limit\' => 5
);
