我一直在撞墙,试图找出为什么我的电子邮件(belongsToMany Guests(belongsToMany电子邮件))不会保存.当我尝试使用关联数据(访客)保存电子邮件模型时,它会在$this->电子邮件 – >保存($email)时失败：
未知类型“”错误
InvalidArgumentException
此时我已经按照CakeBookmarks示例(http://book.cakephp.org/3.0/en/tutorials-and-examples/bookmarks/intro.html)到发球台的关系和编辑表单.甚至构建它并从中提取代码.
这是我项目中的相关代码,感谢任何帮助或推测：
为emails_guests连接表创建语句：
CREATE TABLE emails_guests (
email_id INT NOT NULL,
guest_id INT NOT NULL,
PRIMARY KEY (email_id, guest_id),
FOREIGN KEY guest_key(guest_id) REFERENCES guests(id),
FOREIGN KEY email_key(email_id) REFERENCES emails(id)
);
EmailsTable ::初始化
public function initialize(array $config)
{
// parent::initialize($config);
$this->table('emails');
$this->displayField('title');
$this->primaryKey('id');
$this->addBehavior('Timestamp');
$this->belongsToMany('Guests', [
'foreignKey' => 'email_id',
'targetForeignKey' => 'guest_id',
'joinTable' => 'emails_guests'
]);
}
GuestsTable :: intialize
public function initialize(array $config){
parent::initialize($config);
$this->table('guests');
$this->displayField('name');
$this->primaryKey('id');
$this->addBehavior('Timestamp');
$this->belongsTo('Invitations', [
'foreignKey' => 'invitation_id'
]);
$this->hasMany('Messages', [
'foreignKey' => 'guest_id'
]);
$this->belongsTo('SeatingGroups', [
'foreignKey' => 'seating_group_id'
]);
$this->belongsToMany('Emails', [
'foreignKey' => 'guest_id',
'targetForeignKey' => 'email_id',
'joinTable' => 'emails_guests'
]);
}
电子邮件创建/更新视图manage.ctp
<?= $this->Form->create($email); ?>
<div class="row">
<div class="col-sm-12">
<?= $this->Form->input('title', ['id' => false]); ?>
</div>
</div>
<div class="row">
<div class="col-sm-12">
<?= $this->Form->input('subject'); ?>
</div>
</div>
<div class="row">
<div class="col-sm-12">
<?= $this->Form->input('message', ['class'=>'email-body']); ?>
</div>
</div>
<div class="row">
<div class="col-sm-6">
<?= $this->Form->input(
'guests._ids',
[
// 'type' => 'select',
'options' => $guests,
// 'multiple' => true,
// 'empty' => 'Please select the recipients.',
// 'label'=>'Recipients'
]
); ?>
</div>
<div class="col-sm-6">
<div class="row">
<div class="col-sm-12">
<?= $this->Form->input('send_by', ['id' => 'send-by', 'type' => 'text']); ?>
</div>
</div>
<div class="row">
<div class="col-sm-6">
<?= $this->Form->checkbox('now'); ?>
<label for="now">Send Now</label>
</div>
<div class="col-sm-6">
<?= $this->Form->input(
__('Save'),
[
'type' => 'submit',
'class' => 'inline',
'label' => false
]
) ?>
</div>
</div>
</div>
</div>
<div class="row">
<div class="col-sm-12">
</div>
</div>
<div class="clearfix"></div>
<?= $this->Form->end() ?>
最后,控制器处理有问题的保存：
public function manage($id = null) {
$this->set('title', 'Manage Emails');
if(isset($id)) {
$email = $this->Emails->get($id, [
'contain' => ['Guests']
]);
$this->set('title', 'Email: ' . $email->title);
} else {
$email = $this->Emails->newEntity();
$this->set('title', 'Create Email');
}
if ($this->request->is(['patch', 'post', 'put'])) {
debug($email);
$email = $this->Emails->patchEntity($email, $this->request->data);
debug($email);
debug($this->request->data);
if ($this->Emails->save($email)) {
if($email->now == true) {
$this->process($email->id, $id);
}
$this->Flash->success('The email has been saved.');
return $this->redirect(['action' => 'manage', $email->id]);
} else {
$this->Flash->error('The email could not be saved. Please, try again.');
}
}
$guests = $this->Emails->Guests->find('list')->select(['id', 'first_name', 'last_name', 'email'])->toArray();
$this->set('email', $email);
$this->set('guests', $guests);
$emails = $this->Emails->find();
$this->set('emails', $this->paginate($emails));
$this->set('_serialize', ['emails']);
}
保存电子邮件并选择一个或多个guest虚拟机时触发请求数据(触发无效类型“”错误)：
[
'title' => 'Test Email Edit',
'subject' => 'Hi! {{guest.first_name}}, we're testing some new features!2',
'message' => 'Hi {{guest.first_name}} {{guest.last_name}},
We're testing some new features with recursive data. Let me tell you a bit about you:
Your seating group is: {{guest.seating_group.name}}.
Your invitation is: {{guest.invitation.name}}
Which we sent to: {{guest.invitation.address}}
Thanks! Hope this comes out okay...
',
'guests' => [
'_ids' => [
(int) 0 => '1'
]
],
'send_by' => '',
'now' => '0'
]

根据文档和示例,它应该可以正常工作.提前致谢！
最佳答案 看起来像是读/缓存模式有问题,或者您正在为连接表类定义不正确的主键.使用复合主键,就像您在此处显示的主键一样,它应该永远不会到达抛出该重复项的代码中.
删除tmp / cache / models /,如果你有一个EmailsGuestsTable类,通过Table :: primaryKey()检查它是否及其设置,如果使用,它应该是
['email_id', 'guest_id']
也许你的表最初有一个不同的主键,然后你在不清除缓存和/或更新相应的表类的情况下对它进行了更改.
