CakePHP保存有许多关联

我有一个产品需要将图像路径保存到另一个表。 product hasMany images .

add()

if ($this->request->is('post')) {
    // https://book.cakephp.org/3.0/en/orm/saving-data.html#saving-associations
    $save = $this->Products->newEntity(
        $this->request->getData(),
        ['associated'=>$associated]
    );

    $this->log('JUST AFTER PATCH'.$save);
    $save->last_modified = Time::now();
    $save->created = Time::now();

    //sort out assoc.
    $path = $this->saveImageGetPath($this->request->data['images']);

    $save['images'][] = [
        'path' => $path,
        'alt_description' => $product->name . Time::now() . 'img',
        'position' => $this->request->data['position']
    ];

    $save->isDirty(true);
    $this->log('JUST BEFORE SAVE'.$save);
    if ($this->Products->save($save, [
        'associated'=> ['Shoes', 'Images', 'Products_has_categories']
    ])) {

这是到日志的阵列输出

{
    "name":"xlc",
    "brands_id":1,
    "description":"csvfd",
    "type":"s",
    "position":"0",
    "shoe":{
        "heels_id":1,
        "closures_id":1,
        "materials_upper_id":1,
        "materials_lining_id":1,
        "materials_sole_id":1
    },
    "products_has_categories":{
        "categories_id":"1"
    },
    "images":[
        {
            "path":"\/webroot\/img\/products\/img1503289958.jpg",
            "alt_description":"8\/21\/17, 4:32 AMimg",
            "position":"0"
        }
    ],
    "last_modified":"2017-08-21T04:32:38+00:00",
    "created":"2017-08-21T04:32:38+00:00"
}

这是桌子 Image 协会。

$this->hasMany('Images', [
    'foreignKey' => 'products_id',
    'dependent' => true,
]);

图像上传很好,你可以得到路径。它只是没有为此触发SQL语句,我不知道为什么 hasOne assoc.确实有效,所以我可以保存assoc.但不能用这个 hasMany
