Cakephp外键ID未正确设置答案

【问题标题】：Cakephp Foreign key id not set properlyCakephp外键ID未正确设置
【发布时间】：2017-01-02 04:25:49
【问题描述】：

1..n 或 n..m 数据库表中的参考 ID 未自动设置。请参阅下面的示例。我认为子表中的 client_id 是在任何地方自动设置的，但在我的情况下，在某些情况下它是 0。

要创建：Users.client_id 设置为应为 client.id 但 Contacts.client_id 始终为 0

控制器

这是在 ClientsController.php 中处理的

public function register()
{
    $client = $this->Clients->newEntity();

    if ($this->request->is('post')) {
        $client = $this->Clients->patchEntity($client, $this->request->data, ['associated' => ['Users', 'Users.Contacts' ]]);

        if ($this->Clients->save($client)) {

            $this->Flash->success(__('The user has been saved.'));
            return $this->redirect(['controller' => 'Contracts', 'action' => 'index']);
        } else {
            debug($client);

            $this->Flash->error(__('The user could not be saved. Please, try again.'));
        }
    }
    $this->set(compact('client'));
    $this->set('_serialize', ['client']);
}

问题

一切正常，除了 DB 中的 Contacts.client_id 始终设置为 0。我认为 cakephp 自己处理引用 id 并自动设置它们。

我应该如何扩展我的代码来自动设置这个 client_id？

client_id 确实在我所有的表中，我需要在任何地方自动设置它。

谢谢比伦特

【问题讨论】：

您所看到的是（当前）预期的行为。为什么首先在users 和contacts 表中复制客户端ID？联系人真的可以在没有用户的情况下存在吗？鉴于用户和联系人之间通过其自动递增主键的硬链接，这是在乞求问题。
如果你没有为该列添加任何非空值并且数据类型为整数，它将自动为空，将其更改为允许空
client_id 在某种程度上是我对整个应用程序的强制要求。我在每个表中都有这个 client_id，并且可以直接从每个表中选择当前客户端的有效数据。我想确保数据不属于的其他人不会看到任何数据。是否有关于此行为的文档？如果我理解正确，则没有设置第二级。 $this->Form->input('**users.0.contact.street**',... $this->Form->input('users.0.contact.street_number', ...
您好 NDM，我不明白这种行为。我在联系人$rules->add($rules->existsIn(['client_id'], 'Clients')); 中有此代码@为什么没有真正检查？客户表中没有0 ID，为什么插入表中没有任何异常？
这可能取决于0 的确切生成位置和方式。为了让规则测试一个值，必须预先设置（当然），并且必须将属性标记为脏。我建议您在规则中添加一些断点，并检查何时以及使用何种数据调用它，以及它在何处退出。从这里我能做的就是猜测。

【解决方案1】：

而您缺少自动增量，只需在主键后添加 AUTO_INCREMENT：

  CREATE TABLE clients
  (
     id int NOT NULL AUTO_INCREMENT,
     // other as you did
  )

并尝试替换这一行：

$client = $this->Clients->patchEntity($client, 
$this->request->data, ['associated' => ['Users', 'Users.Contacts' ]]);

通过

$client = $this->Clients->patchEntity($client, 
$this->request->data, ['associated' => ['Users', 'Contacts' ]]); //

【讨论】：

没有改变任何东西！和以前一样的问题。 Users.client_id 已设置，但 Contacts.client_id 为 0
嗨，Khadka，如果我将 Users.Contacts 替换为联系人，我会收到此异常 - 在“联系人”表中找不到主键 [NULL] 的记录，但这应该是自动增量...
您是否尝试在更改后插入新记录？
