Cakephp 3 - belongsToMany 与 _joinData

Question

我尝试在连接 table 中实现与附加数据的 bolongsToMany 关联。连接 table 有外键列和附加列 'context'

articlesController:
$article = $this->Articles->patchEntity($article, $this->request->getData());
debug($article);die;


and in a Plugin-Behavior:
public function beforeMarshal(Event $event, ArrayObject $data, ArrayObject $options)
{
  $data['Categories.Categories'] = ['id' => '1', '_joinData' => ['context' => 'Tag']];
  debug($data);
}

我希望上下文被保存在连接 table 中，但它没有。 debgger 说：

/plugins/Categories/src/Model/Behavior/CategorizeableBehavior.php (line 37)
object(ArrayObject) {
    name => 'dfa'
    description => 'er'
    Categories.Categories => [
        'id' => '1',
        '_joinData' => [
            'context' => 'Tag'
        ]
    ]
}
/src/Controller/ArticlesController.php (line 56)
object(App\Model\Entity\Article) {

    'name' => 'dfa',
    'description' => 'er',
    '[new]' => true,
    '[accessible]' => [
        'name' => true,
        'description' => true,
        'created' => true,
        'modified' => true
    ],
    '[dirty]' => [
        'name' => true,
        'description' => true
    ],
    '[original]' => [],
    '[virtual]' => [],
    '[errors]' => [],
    '[invalid]' => [],
    '[repository]' => 'Articles'

}

我的类别和上下文在哪里。我的代码有什么问题？

Answer 1

如果要附加连接数据，它需要位于嵌套数组中。

$data['Categories.Categories'] = [
      ['id' => '1', '_joinData' => ['context' => 'Tag']]
];

它必须是一个嵌套数组，以便您可以附加多条记录（如果您也想要的话）。
