【问题描述】：
我正在尝试使用具有 ClientContactAddresses 关联的 patchEntity() 函数更新 ClientContactName 实体。 ClientContactName 实体按我的预期更新。然而，即使 ClientContactAddress 是一个现有的实体，patchEntity() 函数也会创建一个 new ClientContactAddress 实体，并将其添加到表中保存。
如果我在视图中包含一个隐藏的 id 字段并将 id 添加为关联数组中的 accessibleField，它确实会更新现有的 ClientContactAddress，但我难以想象这是做事的正确方式。
我的问题是：我如何对修补函数进行编码，以便更新现有关联而不是创建新关联？
关系是 ClientContactName hasMany ClientContactAddresses。下面是我的代码，没有隐藏的id 字段和accessibleField 调整。
我在控制器中的edit() 函数如下所示：
public function edit($id = null)
{
$clientContactName = $this->ClientContactNames->get($id, [
'contain' => [
'Clients',
'ClientContactAddresses'
]
]);
if ($this->getRequest()->is(['patch', 'post', 'put'])) {
$data = $this->getRequest()->getData();
$clientContactName = $this->ClientContactNames->patchEntity(
$clientContactName,
$data, [
'associated' => ['ClientContactAddresses']
]
);
if ($this->ClientContactNames->save($clientContactName)) {
$this->Flash->success(__('The client contact has been saved.'));
return $this->redirect(['controller' => 'Clients', 'action' => 'view', $clientContactName->client->id]);
}
$this->Flash->error(__('The client contact could not be saved. Please, try again.'));
}
$this->set(compact('clientContactName'));
}
视图如下所示：
<div class="container-fluid clearfix col-lg-10">
<?= $this->Form->create($clientContactName) ?>
<fieldset>
<!--bits that matter-->
<div class="row stack-row">
<div class="col-6">
<?= $this->Form->control('first_name') ?>
</div>
<div class="col-6">
<?= $this->Form->control('last_name') ?>
</div>
</div>
<?= $this->element('address_form', ['showTopper' => true, 'entity' => 'client_contact_addresses.0']) ?>
</fieldset>
<?= $this->Form->button(__('Submit'), ['class' => 'btn btn-primary']) ?>
<?= $this->Form->end() ?>
</div>
这是元素：
<?php
$prefix = ((empty($entity)) ? '' : $entity . '.');
if (!empty($showTopper)):
?>
<div class="row stack-row">
<div class="col">
<legend class="sub-topper"><?= __('Address') ?></legend>
</div>
</div>
<?php endif; ?>
<div class="row stack-row">
<div class="col-lg-6">
<?php
echo $this->Form->control($prefix . 'address_1');
echo $this->Form->control($prefix . 'address_2');
echo $this->Form->control($prefix . 'address_3');
?>
</div>
</div>
<!--etc.-->
在打补丁之前，实体的相关部分如我所料，即[new]设置为false：
object(App\Model\Entity\ClientContactName) {
'id' => (int) 1,
'first_name' => 'xxxx',
'last_name' => 'xxxx',
'client_id' => (int) 19,
'client_contact_addresses' => [
(int) 0 => object(App\Model\Entity\ClientContactAddress) {
'id' => (int) 12,
'address_1' => 'xxxx',
'address_2' => 'xxxx',
'address_3' => 'xxxx',
etc...
'client_contact_name_id' => (int) 1,
'[new]' => false,
'[accessible]' => [
'address_1' => true,
'address_2' => true,
'address_3' => true,
etc.
'client' => true
],
'[dirty]' => [],
'[original]' => [],
'[virtual]' => [],
'[hasErrors]' => false,
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'ClientContactAddresses'
}],
//..//
请求数据显示地址字段值。虽然因为我没有隐藏的 id 字段，所以不会出现 id 值：
'first_name' => 'xxxx',
'last_name' => 'xxxx',
'client_contact_addresses' => [
(int) 0 => [
'address_1' => 'xxxx',
'address_2' => 'xxxx',
'address_3' => 'xxxx',
etc.
]
],
并且在打补丁之后，新实体就创建好了，即[new]设置为true：
object(App\Model\Entity\ClientContactName) {
'id' => (int) 1,
'first_name' => 'xxxx',
'last_name' => 'xxxx',
'client_id' => (int) 19,
'client_contact_addresses' => [
(int) 0 => object(App\Model\Entity\ClientContactAddress) {
'address_1' => 'xxxx',
'address_2' => 'xxxx',
'address_3' => 'xxxx',
etc.
'[new]' => true,
'[accessible]' => [
'address_1' => true,
'address_2' => true,
'address_3' => true,
etc.
'id' => true
],
'[dirty]' => [
'address_1' => true,
'address_2' => true,
'address_3' => true,
etc.
],
'[original]' => [],
'[virtual]' => [],
'[hasErrors]' => false,
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'ClientContactAddresses'
}],
//..//
