Question

我正在创建一个包含以下表格的电子商务网站：

    articles
    sizes
    colors
    orders
    articles_colors(article_id,color_id)
    articles_sizes(article_id,size_id)
    articles_orders(article_id,order_id,size_id,color_id,quantity)

我的表格文件：

ArticlesTable.php

    $this->belongsToMany('Colors', [
        'foreignKey' => 'article_id',
        'targetForeignKey' => 'color_id',
        'joinTable' => 'articles_colors'
    ]);
    $this->belongsToMany('Orders', [
        'through' => 'ArticlesOrders'
    ]);
    $this->belongsToMany('Sizes', [
        'foreignKey' => 'article_id',
        'targetForeignKey' => 'size_id',
        'joinTable' => 'articles_sizes'
    ]);

OrdersTable.php

    $this->belongsToMany('Articles', [
        'through'=>'ArticlesOrders'
    ]);

ArticlesOrdersTable.php

    $this->belongsTo('Articles', [
        'foreignKey' => 'article_id',
        'joinType' => 'INNER'
    ]);
    $this->belongsTo('Orders', [
        'foreignKey' => 'order_id',
        'joinType' => 'INNER'
    ]);
    $this->belongsTo('Sizes', [
        'foreignKey' => 'size_id',
        'joinType' => 'INNER'
    ]);
    $this->belongsTo('Colors', [
        'foreignKey' => 'color_id',
        'joinType' => 'INNER'
    ]);

问题在于，当我收到订单时，我不知道如何在Article对象中获取joinData的大小和颜色。例如：

$order = $this->Orders->get($id, [
        'contain' => ['Articles']
    ]);

结果：

articles: [
'_joinData' => object(App\Model\Entity\ArticlesOrder) {

            'article_id' => (int) 2,
            'id' => (int) 1,
            'order_id' => (int) 57,
            'price' => (float) 100,
            'color_id' => (int) 1,
            'size_id' => (int) 2,
            //I would like to have the size and the color object
]

感谢您的帮助：）
