Accounts表具有引用Users表id的外键user_id。
我一直在尝试完成AccountsController的添加功能。目前，如果它是不存在的用户，它可以将记录添加到我的Accounts表和Users表（关联）中。当我尝试将帐户添加到现有用户时出现问题（错误我得到“在表中找不到记录”帐户“主键[NULL]”;有关此内容的更多信息）。 我有一个用户表的原因是因为它将包含公共用户（通过提供电子邮件订阅;没有帐户）和注册用户（注册用户将拥有一个帐户）。 我认为发生此问题的原因是因为电子邮件在UsersTable（规则）中不是唯一的。
public function add()
{
$account = $this->Accounts->newEntity();
if ($this->request->is('post')) {
$account = $this->Accounts->patchEntity($account, $this->request->data);
if ($this->Accounts->save($account)) {
$this->Flash->success('The account has been saved.');
return $this->redirect(['action' => 'index']);
}else {
$this->Flash->error('The account could not be saved. Please, try again.');
}
}
$users = $this->Accounts->Users->find('list', ['limit' => 200]);
$this->set(compact('account', 'users'));
$this->set('_serialize', ['account']);
}
<?= $this->Form->create($account); ?>
<fieldset>
<legend><?= __('Add Account') ?></legend>
<?php
echo $this->Form->input('user.name');
echo $this->Form->input('user.email');
echo $this->Form->input('password');
echo $this->Form->input('phonenumber');
echo $this->Form->input('address');
echo $this->Form->input('user.postcode');
?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>
</div>
注意：有关表格在表格中的字段的信息，因此我不会详细介绍它们。但是帐户表也会有一个id和user_id; user表将具有与user_id和usertype（admin，client或public）相关联的id。
我一直试图通过尝试使用user.email从Users表中检索行来解决这个问题，但我无法访问它。如果我可以访问它，我应该能够从Users表中检索关联的行，从Users表中获取id，然后以某种方式将我的Accounts记录的user_id设置为该id。 我曾尝试从表单中请求数据，但它只适用于与帐户模型相关的输入（至少我认为它是如何工作的）。
很多人会感激不尽。如果我的想法错了，请告诉我。我非常感谢（不要求）我的问题的答案是否以外行的方式解释。
编辑：用户表将包含管理员，具有用于购买服务的注册帐户的用户以及仅想要订阅的用户。后者只需要提供比注册用户更少的信息，因此存在用户表和帐户表的原因。登录的唯一方法是使用users表（包含电子邮件）和accounts表（包含密码）。
编辑2 ：我基本上想要这样做。
public function add()
{
$account = $this->Accounts->newEntity();
if ($this->request->is('post')) {
$account = $this->Accounts->patchEntity($account, $this->request->data);
if ($this->Accounts->save($account)) {
$this->Flash->success('The account has been saved.');
return $this->redirect(['action' => 'index']);
}else {
$this->Flash->error($this->request->data['address']);
}
}
$users = $this->Accounts->Users->find('list', ['limit' => 200]);
$this->set(compact('account', 'users'));
$this->set('_serialize', ['account']);
}
以上工作并报告输入的地址。
public function add()
{
$account = $this->Accounts->newEntity();
if ($this->request->is('post')) {
$account = $this->Accounts->patchEntity($account, $this->request->data);
if ($this->Accounts->save($account)) {
$this->Flash->success('The account has been saved.');
return $this->redirect(['action' => 'index']);
}else {
$this->Flash->error($this->request->data['user.email']);
}
}
$users = $this->Accounts->Users->find('list', ['limit' => 200]);
$this->set(compact('account', 'users'));
$this->set('_serialize', ['account']);
}
这不起作用并给我错误： 注意（8）：未定义的索引：user.email [APP / Controller \ AccountsController.php，第68行]
我想获取user.email，然后我可以在我的Users表中搜索该行并检索它的主键（插入我想要创建的帐户的user_id）。
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(255),
email VARCHAR(255),
postcode VARCHAR(255),
usertype VARCHAR(20) DEFAULT 'Public',
created DATETIME,
updated DATETIME
);
CREATE TABLE accounts (
id INT AUTO_INCREMENT PRIMARY KEY,
user_id INT NOT NULL,
password VARCHAR(255),
phonenumber VARCHAR(10),
address VARCHAR(255),
created DATETIME,
updated DATETIME,
FOREIGN KEY user_key (user_id) REFERENCES users(id)
);
编辑3 ：我发现从表单中检索关联数据的方式（或者更确切地说，修补后的实体$帐户）是通过$ account-＆gt; user-＆gt;电子邮件。 我正在某个地方，但这是为现有用户（公共）注册帐户的一种非常肮脏的方式。
public function add()
{
$account = $this->Accounts->newEntity();
if ($this->request->is(['post', 'patch', 'put'])) {
$account = $this->Accounts->patchEntity($account, $this->request->data);
if ($this->Accounts->save($account)) {
$users = $this->Accounts->Users;
$query = $users->query();
$query->update()
->set([
'usertype'=>'Client'
])
->where(['email' => $account->user->email])
->execute();
$this->Flash->success('The account has been saved.');
return $this->redirect(['action' => 'index']);
}else {
$users = $this->Accounts->Users;
$query = $users->query();
$usertype = $query->select('usertype')
->where(['email' => $account->user->email]);
if(true){
$query->update()
->set(['name'=>$account->user->name,
'postcode'=>$account->user->postcode,
'usertype'=>'Client'
])
->where(['email' => $account->user->email])
->execute();
//everything up to this point works
$userid = $query->select('id')
->where(['email' => $account->user->email]);
$accounts = $this->Accounts;
$query = $accounts->query();
$query->insert(['user_id', 'password', 'phonenumber', 'address'])
->values([
'user_id' => $userid,
'password' => $this->request->data['password'],
'phonenumber' => $this->request->data['phonenumber'],
'address' => $this->request->data['address']
])
->execute();
$this->Flash->success('The account has been saved.');
return $this->redirect(['action' => 'index']);
}
else{
$this->Flash->error('The account could not be saved.');
}
}
}
$users = $this->Accounts->Users->find('list', ['limit' => 200]);
$this->set(compact('account', 'users'));
$this->set('_serialize', ['account']);
}
现在的问题是通过查询构建器将user_id输入到我的帐户行。目前，它成功地更改了我的用户的usertype，但之后当我尝试在我的Accounts表中插入一行时，我得到了这个。错误：SQLSTATE [21000]：基数违规：1241操作数应包含1列。
另外sql错误是这个 - ＆gt; INSERT INTO帐户（user_id，密码，电话号码，地址）VALUES（（SELECT Users.usertype AS Users__usertype，Users.id AS Users__id FROM users Users WHERE（email =：c0 AND email =：c1 AND email =：c2））,: c3，：c4，：c5）
我不知道为什么它试图将两列放入一个字段中。非常感谢。 在写完这篇文章后，我意识到在有电子邮件情况的情况下执行了3个查询。似乎已加入查询。

公共功能add（） {

//the above query will delete a user if the email provided matches and their usertype is public
//subsequently, this code will delete and add a user; not update user. ie. their id will change.
if ($this->Accounts->save($account)) {
$users = $this->Accounts->Users;
$query = $users->query();
$query->update()
->set([

}
新功能将使用提供的电子邮件删除用户，其中usertype为“Public”;它只会删除1，因为电子邮件是唯一的。然后它将像往常一样用作默认的添加功能，并将新用户（或已删除但随后添加的）用户类型编辑为“客户端”。
