mongodb + yii2：如何将 array/object 推送到 mongodb？

Question

我正在玩 yii2 和 mongodb，我被困在一个点上。我使用 mongodb GII 创建了 CRUD 功能。现在我正在修改以将数组对象放入我的数据库记录中。

在创建客户时，我创建了一个里程对象并像这样推送它。

$model = new Customer();
if ($model->load(Yii::$app->request->post())) {
    $mileage = new mileage(2, 'British Airways', 'Usman', 10000);
    $model->mileage = array($mileage);
    $model->save();
    return $this->redirect(['view', 'id' => (string) $model->_id]);
}

mileage.php

class Mileage {
    public $_id;
    public $sm_order_id;
    public $program;
    public $customer;
    public $miles;

    public function __construct($sm_order_id, $program, $customer, $miles) {
        $this->_id = new \MongoId();
        $this->sm_order_id = $sm_order_id;
        $this->program = $program;
        $this->customer = $customer;
        $this->miles = $miles;
    }
}

并且我在数据库中获取了以下格式的数据：

array (
  '_id' => 
  MongoId::__set_state(array(
     '$id' => '569cd9ed9eb8954c2000002c',
  )),
  'name' => 'Alan',
  'email' => 'alan@abc.com',
  'address' => 'New York',
  'mileage' => 
  array (
    0 => 
    array (
      '_id' => 
      MongoId::__set_state(array(
         '$id' => '569cd9ed9eb8954c2000002b',
      )),
      'sm_order_id' => 2,
      'program' => 'British Airways',
      'customer' => 'Wake',
      'miles' => 10000,
    ),
  ),
)

现在我想要一种机制，这样我就可以在里程节点中添加更多 array/objects。我搜索了很多但没有找到任何东西。相同格式的数据库如下：

array (
  '_id' => 
  MongoId::__set_state(array(
     '$id' => '569cd9ed9eb8954c2000002c',
  )),
  'name' => 'Alan',
  'email' => 'alan@abc.com',
  'address' => 'New York',
  'mileage' => 
  array (
    0 => 
    array (
      '_id' => 
      MongoId::__set_state(array(
         '$id' => '569cd9ed9eb8954c2000002b',
      )),
      'sm_order_id' => 2,
      'program' => 'British Airways',
      'customer' => 'Wake',
      'miles' => 5000,
    ),
    1 => 
    array (
      '_id' => 
      MongoId::__set_state(array(
         '$id' => '569cd9ed9eb8954c2000002c',
      )),
      'sm_order_id' => 7,
      'program' => 'Qatar Airways',
      'customer' => 'Tony',
      'miles' => 2500,
    ),
  ),
  2 =>
  array (
  .........
  .........
  ),
)

好的，我很久以前就找到了解决方案，我想我应该在这里分享它。所以我像这样推动里程节点中的第一个对象：

$model = Customer::findOne($customerId);
if ($model->load(Yii::$app->request->post())) {
    $mileage = new mileage(2, 'British Airways', 'Usman', 10000);
    $model->mileage = array($mileage);
    $model->save();
    return $this->redirect(['view', 'id' => (string) $model->_id]);
}

所以要在里程节点中添加另一个对象，我们需要做的是我们需要从数据库中获取客户对象，我们必须检查里程节点中是否已经添加了一个对象，然后我必须获取该对象并将新创建的 mileage array/object 推入其中。修改后的代码如下：

$model = Customer::findOne($customerId);
if ($model->load(Yii::$app->request->post())) {
    $mileage = new mileage(2, 'British Airways', 'Kamran', 9000);
    if (empty($model->mileage) || count($model->mileage) == 0) {
        $model->mileage = array($mileage);
    } else {
        $allUsedMiles = $model->mileage;
        array_push($allUsedMiles, $mileage);
        $model->mileage = $allUsedMiles;
    }
    $model->save();
    return $this->redirect(['view', 'id' => (string) $model->_id]);
}

我希望这对以后的人有所帮助 ;) 谢谢，
