我遇到了一个问题，即 CakePHP 忽略了保存我指定的字段，而是创建了额外的记录。我正在使用CakePHP 2.3.6。
我的表如下所示：
CREATE TABLE `events_guests` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`guest_id` int(11) NOT NULL,
`event_id` int(11) NOT NULL,
`promoter_id` int(11) DEFAULT NULL,
`created` datetime NOT NULL,
`modified` datetime NOT NULL,
`attended` varchar(15) NOT NULL DEFAULT 'No',
PRIMARY KEY (`id`)
)
这是代码
public function addGuest($event_id, $promoter_id = null) {
if ($this->request->is('post')) {
$this->Guest->create();
$event_data = array('event_id' => $event_id);
$data = $this->request->data;
$data['Event'] = $event_data;
if($promoter_id) {
$data['Event']['promoter_id'] = $promoter_id;
}
if ($this->Guest->saveAssociated($data)) {
$this->Session->setFlash(__('The guest has been added to the guestlist'), 'flash/success');
} else {
$this->Session->setFlash(__('The guest could not be saved. Please, try again.'), 'flash/error');
}
这是我尝试保存的数据：
Array (
[Guest] => Array
(
[first_name] => Joe
[last_name] => Schmoe
)
[Event] => Array
(
[event_id] => 1
[promoter_id] => 2
)
)
我的模特遵循：
class Guest extends AppModel {
public $hasAndBelongsToMany = array(
'Event' => array(
'className' => 'Event',
'joinTable' => 'events_guests',
'foreignKey' => 'guest_id',
'associationForeignKey' => 'event_id',
'unique' => 'true',
),
'Promoter' => array(
'className' => 'Promoter',
'joinTable' => 'events_guests',
'foreignKey' => 'guest_id',
'associationForeignKey' => 'promoter_id',
'unique' => 'true',
)
);
}
和
class Event extends AppModel {
public $hasAndBelongsToMany = array(
'Guest' => array(
'className' => 'Guest',
'joinTable' => 'events_guests',
'foreignKey' => 'event_id',
'associationForeignKey' => 'guest_id',
'unique' => 'keepExisting',
'order' => 'last_name',
),
'Promoter' => array(
'className' => 'Promoter',
'joinTable' => 'events_promoters',
'foreignKey' => 'event_id',
'associationForeignKey' => 'promoter_id',
'unique' => 'keepExisting',
)
);
}
由此得出的结果是 2 条记录 事件客人，都没有promoter_id .
一条记录按预期接收event_id = 1
其他记录接收event_id = 2，这实际上是promoter_id
我尝试混合使用saveAssociated和saveAll
任何帮助将不胜感激！谢谢！
参考：Cakephp 在 HABTM 关系中保存额外的属性
对于您的问题，请不要使用 HABTM，因为 HABTM 通常用于连接 2 个表。
因此，如果您有 2 个以上的字段，请创建一个模型并像 belongsTo 和 具有许多关系一样使用它。
class Event extends AppModel {
$hasMany = array(
'EventGuest' => array(
'className' => 'EventGuest',
'foreignKey' => 'event_id'
)
);
}
class Guest extends AppModel {
$hasMany = array(
'EventGuest' => array(
'className' => 'EventGuest',
'foreignKey' => 'guest_id'
)
);
}
class Promoter extends AppModel {
$hasMany = array(
'EventGuest' => array(
'className' => 'EventGuest',
'foreignKey' => 'promoter_id'
)
);
}
现在，您的关系模型。
class EventGuest extends AppModel {
$belongsTo = array(
'Event' => array(
'className' => 'Event',
'foreignKey' => 'event_id'
),
'Guest' => array(
'className' => 'Guest',
'foreignKey' => 'guest_id'
),
'Promoter' => array(
'className' => 'Promoter',
'foreignKey' => 'promoter_id'
)
);
}
并继续使用您的代码。
public function addGuest($event_id, $promoter_id = null) {
if ($this->request->is('post')) {
$this->Guest->create();
$event_data = array('event_id' => $event_id);
$data = $this->request->data;
$data['Event'] = $event_data;
if($promoter_id) {
// EDITED
$data['Promoter']['promoter_id'] = $promoter_id;
}
if ($this->Guest->saveAssociated($data)) {
$this->Session->setFlash(__('The guest has been added to the guestlist'), 'flash/success');
} else {
$this->Session->setFlash(__('The guest could not be saved. Please, try again.'), 'flash/error');
}
}
}
