Question

我试图更新/保存可以有多个地址关联的TradingPartner实体（客户和供应商）（TradingPartnerAddresses）。

我有一系列已更改的TradingPartners，我使用Cake的patchEntities（）函数将现有记录与修改后的记录合并。

问题是Cake错误地将关联的地址标记为脏，并且当循环通过实体以保存它们时，它试图重新插入现有地址 - 导致重复的地址。

以下代码：

贸易伙伴控制器

//Load the trading partners model
$tradingPartners = TableRegistry::get('TradingPartners');

//find all existing trading partners and their associated addresses
$currentTradingPartners = $tradingPartners->find('all')
                                     ->contain(['TradingPartnerAddresses']);

//Patch trading partner changes
//Cake automagically handles 1 level of associations
$patchedTpEntities = $tradingPartners->patchEntities($currentTradingPartners, $partners);

//loop through and save all dirty fields
foreach ($patchedTpEntities as $tpEntity) {
   if ($tradingPartners->save($tpEntity)) {
   } else {
      //TODO
   }
}

贸易伙伴表

public function initialize(array $config) {
    $this->primaryKey('partner_code');

    $this->hasMany('TradingPartnerAddresses', [
        'foreignKey' => 'partner_code'
    ]);
}

贸易伙伴地址表

public function initialize(array $config) {
    $this->entityClass('App\Model\Entity\TradingPartnerAddress');
    $this->belongsTo('TradingPartners', [
        'foreignKey' => 'partner_code'
    ]);
}

调试（$ patchedEtentites）;

(int) 0 => object(App\Model\Entity\TradingPartner) {

    .....

    'trading_partner_addresses' => [],
    '[new]' => false,
    '[accessible]' => [
        '*' => true
    ],
    '[dirty]' => [
        'trading_partner_addresses' => true
    ],
    '[original]' => [],
    '[virtual]' => [],
    '[errors]' => [],
    '[repository]' => 'TradingPartners'

任何想法为什么trade_partner_addresses在实际清理时被标记为脏？

Answer 1

当您使用某些数据修补某个实体时，它会自动标记为脏

$tradingPartners->patchEntities($currentTradingPartners, $partners);

这意味着您正在使用$ partners数据更新$ currentTradingPartners，因此$ currentTradingPartners被修改并标记为脏。

如果你想要原始数据你可以在你的entiy属性上使用getOriginal方法，你也可以用clean方法删除脏标志。

如果你有问题来修补具有关联的实体你必须在patchEntity中传递一系列选项：

$article = $articles->get(1);
$articles->patchEntity($article, $this->request->data(), [
  'associated' => ['Tags', 'Comments.Users']
]);
