Cakephp 3.x节省了很多关联

在我的项目中，我无法在单个保存中保存hasmany关联表。我的关联如下：

类ProductsTable扩展表

$this->hasMany('ProductImages', [
            'foreignKey' => 'product_id',
            'joinType' => 'INNER'
        ]);

类ProductImagesTable扩展了表

$this->belongsTo('Products', [
        'foreignKey' => 'product_id',
        'joinType' => 'INNER'
    ]);

在我的控制器中，代码如下

debug($this->request->data);  \src\Controller\Admin\ProductsController.php (line 81)

$product = $this->Products->patchEntity($product, $this->request->data, [
    'associated' => [ 'ProductImages']
]); 
debug($product);\src\Controller\Admin\ProductsController.php (line 86)
$this->Products->save($product);

调试结果如下

 \src\Controller\Admin\ProductsController.php (line 81)

[
    'name' => 'Lorem ipsum dolor',
    'short_description' => ' Lorem ipsum dolor sit amet',
    'description' => ' Lorem ipsum dolor sit amet ',
    'sku' => 'NE132W',
    'price' => '51',
    'product_image' => [
        (int) 0 => [
            'default' => (int) 0,
            'image_name' => 'product1',
            'real_name' => '631-1478785843.png',
            'image_url' => 'http://cakephp-apps.com/mykipferl/img/Products/631-1478785843.png'
        ],
        (int) 1 => [
            'default' => '1',
            'image_name' => 'product2',
            'real_name' => '140-1478785850.png',
            'image_url' => 'http://cakephp-apps.com/mykipferl/img/Products/140-1478785850.png'
        ],
        (int) 2 => [
            'default' => (int) 0,
            'image_name' => 'product3',
            'real_name' => '416-1478785856.png',
            'image_url' => 'http://cakephp-apps.com/mykipferl/img/Products/416-1478785856.png'
        ]
    ]
]

\src\Controller\Admin\ProductsController.php (line 86)

object(App\Model\Entity\Product) {

    'name' => 'Lorem ipsum dolor',
    'short_description' => ' Lorem ipsum dolor sit amet',
    'description' => ' Lorem ipsum dolor sit amet, consectetur adipiscing elit.  ',
    'sku' => 'NE132W',
    'price' => (float) 51,
    'product_image' => [
        (int) 0 => [
            'default' => (int) 0,
            'image_name' => 'product1',
            'real_name' => '631-1478785843.png',
            'image_url' => 'http://cakephp-apps.com/mykipferl/img/Products/631-1478785843.png'
        ],
        (int) 1 => [
            'default' => '1',
            'image_name' => 'product2',
            'real_name' => '140-1478785850.png',
            'image_url' => 'http://cakephp-apps.com/mykipferl/img/Products/140-1478785850.png'
        ],
        (int) 2 => [
            'default' => (int) 0,
            'image_name' => 'product3',
            'real_name' => '416-1478785856.png',
            'image_url' => 'http://cakephp-apps.com/mykipferl/img/Products/416-1478785856.png'
        ]
    ],
    '[new]' => true,
    '[accessible]' => [
        '*' => true
    ],
    '[dirty]' => [
        'name' => true,
        'short_description' => true,
        'description' => true,
        'sku' => true,
        'price' => true,
        'product_image' => true
    ],
    '[original]' => [],
    '[virtual]' => [],
    '[errors]' => [],
    '[invalid]' => [],
    '[repository]' => 'Products'

}

有人帮我解决了这个问题吗？

答案 0 :(得分：3)

您必须为关联使用适当的属性名称，hasMany关联默认为关联别名的复数，下划线变体，因此在您的情况下product_images，而不是{{1 }}
