CakePHP 3.x - 保存在关联表中不起作用

Question

我有下表结构。

委托人表

class MandatorTable extends Table
{
public function initialize(array $config)
    {
        $this->table('mandators');

        $this->belongsToMany('Seminar', [
            'foreignKey' => 'mandator_id',
            'targetForeignKey' => 'seminar_id',
            'joinTable' => 'mandators_seminars'
        ]);
    }
}

半桌

class SeminarTable extends Table
{
    public function initialize(array $config)
    {
        $this->table('seminars');

        $this->belongsToMany('Mandator', [
            'foreignKey' => 'seminar_id',
            'targetForeignKey' => 'mandator_id',
            'joinTable' => 'mandators_seminars'
        ]); 
    }   
}

两个表都属于'mandators_seminars'表

mandator_id，seminar_id

当我保存数据时，它会保存在研讨会表中，但不会保存在“mandators_seminars”表中

查询

$seminartable = $this->Seminar->newEntity();

$this->request->data['mandator'][0] = 1;

$seminardata = $this->Seminar->patchEntity($seminartable, $this->request->data);
$this->Seminar->save($seminardata)

请求数据

Array
(
    [bookable] => test
    [released] => aaa
    [linkable] => bb
    [name] => ccc
    [internalnote] => ddd
    [abstract] => ttt
    [description] => ddd
    [Category] => 14
    [mandator] => Array
        (
            [0] => 1
        )

    [mandator_owner_id] => 1
)

Answer 1

看你有两个表 Mandator 和 Similar as single ，但你的连接表是复数。首先检查这个。如果还有问题，请查看CakePHP Through Association

如您所见，您的关联应该是这样的：

$this->belongsToMany('Mandator', [
        'foreignKey' => 'seminar_id',
        'targetForeignKey' => 'mandator_id',
        'through' => 'PluginName.MandatorsSeminars'
        'joinTable' => 'mandators_seminars',
        'className' => 'PluginName.Mandator'
    ]); 

还有一个提示：table 应该被称为复数形式。
