【问题描述】:
Products belongsToMany ProductCircles 到 ProductsInCircles。
ProductsInCirclesTable.php
public function initialize(array $config)
{
$this->table('products_in_circles');
$this->displayField('id');
$this->primaryKey('id');
$this->belongsTo('Products', [
'foreignKey' => 'product_id'
]);
$this->belongsTo('ProductCircles', [
'foreignKey' => 'product_circle_id'
]);
}
ProductsTable.php
public function initialize(array $config)
{
$this->table('products');
$this->displayField('name');
$this->primaryKey('id');
$this->belongsToMany('ProductCircles', [
'through' => 'ProductsInCircles',
]);
}
当我通过products/edit/{id} 编辑Product 时,我将提供来自$this->request->data 的以下数据
Array
(
[name] => Piuma
[attributes_in_json] => {"size":"large"}
[rooms] => Array
(
[0] => 2
)
[styles] => Array
(
[0] => 15
[1] => 16
)
[materials] => Array
(
[0] => 27
)
[product_circles] => Array
(
[_ids] => Array
(
[0] => 2
[1] => 15
[2] => 16
[3] => 27
)
)
[associated] => Array
(
[0] => ProductCircles
)
)
以下代码没有将关联数据保存到products_in_circles表中
$product = $this->Products->patchEntity($product, $this->request->data);
$product->dirty('product_circles', true);
if ($this->Products->save($product)) {
我也试过
$product = $this->Products->patchEntity($product, $this->request->data, ['associated' => ['ProductCircles']]);
if ($this->Products->save($product)) {
与
$product = $this->Products->patchEntity($product, $this->request->data);
if ($this->Products->save($product, ['associated' => ['ProductCircles']])) {
与
$product = $this->Products->patchEntity($product, $this->request->data, ['ProductCircles']);
if ($this->Products->save($product)) {
如何将这些正确保存到products_in_circles 表中?
我当然也想使用append 选项而不是replace。
我查看了文档,该示例对于创建新实体更加清晰。我的是用于编辑现有实体。
另外,我找不到打开append 选项的位置。见http://book.cakephp.org/3.0/en/orm/saving-data.html#saving-belongstomany-associations
我怀疑我在数据结构上犯了一个错误。
请指教。
编辑
产品实体
class Product extends Entity
{
/**
* Fields that can be mass assigned using newEntity() or patchEntity().
*
* @var array
*/
protected $_accessible = [
'name' => true,
'attributes_in_json' => true,
'created_by' => true,
'modified_by' => true,
'prices' => true,
];
}
【问题讨论】:
-
您的 Product 实体类中是否可以访问
product_circles属性? -
添加了产品实体代码。不,我没有 product_circles 作为可访问属性。这很关键吗?
-
好的,看起来这是必要的。谢谢洛伦佐
-
你知道在哪里使用“附加”选项吗?
