Question

我有一个查询，使用cakephp中的Containable行为，如下所示：

    $x = $this->find('first',array('contain'=>array(
    'User' => array(
        'SelectionsTeam' => array('conditions' => $conditionTeamSelection,
            'Team' => array(
                        'fields' => array('name','city','id'),
                            'TeamsStat' => $condition,
                                            ),
            'PointsHistory' => array('fields' => array('points'))
                                    ),

    ),
   'conditions' => array('id'=>$id)
));

Everythings运行良好但PointsHistory表返回我，例如10行，1个字段（点）。如何直接在可包含的中获取每行10行的SUM。因为现在，我需要做一个foreach并得到每个PointsHistory行的总和，我认为这是可以避免的。

在决赛中，我希望表格如下：[PointsHistory] => [Total] => 10

而不是：

[PointsHistory] => [0] => ['points'] => 2 [1] => ['points'] => 1 [2] => ['points'] => 3

等

我认为不可能完全得到

[PointsHistory] => [Total] => 10

但我相信你所寻找的是：

    $x = $this->find('first',array('contain'=>array(
    'User' => array(
        'SelectionsTeam' => array('conditions' => $conditionTeamSelection,
            'Team' => array(
                        'fields' => array('name','city','id'),
                            'TeamsStat' => $condition,
                                            ),
            'PointsHistory' => array('fields' => array('SUM(points) total_points'))
                                    ),

    ),
   'conditions' => array('id'=>$id)
));

结果如下：

[PointsHistory] => [0] => [Total] => 10

我还没有测试过，所以将调试级别更改为2并查看它生成的代码：）

CakePhp，在Containable中获得许多行的总数
