CakePHP LEFT JOIN 排序问题

Question

我正在使用 cakePhp 2.x 版本，下面是我的数据网格视图和控制器，我希望区域和框都按用户排序。 Box 可以排序，但是Area first sorting 是有效的，点击排序之后，页面刷新了但是没有排序。可能是什么原因？

<table class="index">
<thead>
    <tr>
        <th><?php echo $this->Paginator->sort('A.title', 'Area')?></th>
        <th><?php echo $this->Paginator->sort('B.title', 'Boxes')?></th>
        <th>Internal</th>
        <th>External</th>
    </tr>
</thead>

$this->paginate['contain'] = array();
$this->paginate['joins'] = array(
    array(
        'table' => 'a_table',
        'alias' => 'A',
        'type' => 'LEFT',
        'conditions' => array(
            'A.key = B.id',
            'A.status' => 'Active'
        )
    )
);

$conditions = array();
$this->paginate['fields'] = array('B.*', 'A.title');
$this->paginate['order'] = array('A.title', 'B.title');

if(!empty($this->request->data['SignalBox']))
{
    if($this->request->data['SignalBox']['box'])
        $conditions['B.title LIKE'] = '%'.$this->request->data['SignalBox']['box'].'%';

    if($this->request->data['SignalBox']['area'])
        $conditions['A.title'] = $this->request->data['SignalBox']['area'];
}

if($conditions)
    $this->paginate['conditions'] = $conditions;

$data = $this->paginate('B');

$this->set('data', $data);

Answer 1

最终解决方案是，更改模型根据提交的排序列，

$model ='A';

if($this->request->param('named.sort')){
    $submittedModel = explode('.',$this->request->param('named.sort'));
    $model =$submittedModel [0];
}

然后更改 JOIN 查询并 $data = $this->paginate('B');

if(A)
{
   A JOIN query
}
else
{
   B JOIN query
}
