防止patchEntity（）删除重复项

Question

我正在尝试保存一个与BelongsToMany相关联的实体，即订购BelongsToMany产品。 我的联合表包含我需要保存的重要数据，即使产品ID重复也是如此。联合表中尚未创建唯一键。 但是，patchEntity阻止了我这样做，因为它会删除重复的产品。

OrdersTable.php

class OrdersTable extends Table
{
    public function initialize(array $config)
    {
        parent::initialize($config);

        $this->belongsToMany('Products', [
            'foreignKey' => 'order_id',
            'targetForeignKey' => 'product_id',
            'joinTable' => 'orders_products',
            'through' => 'OrdersProducts'
        ]);
    }
}

这是我的POST，您可以在其中看到ID为1772的产品被多次插入。

'products' => [
    (int) 0 => [
        '_joinData' => [
            'id' => '50',
            'order_id' => '',
            'product_name' => '- name -',
            'exception_id' => '',
            'exception_name' => '',
            'weft' => '100',
            'warp' => '100',
            'manufacture_name' => 'AC',
            'real_cost' => '1.2',
            'ordered_quantity' => '32',
            'received_quantity' => '2',
            'difference' => '30'
        ],
        'id' => '1772'
    ],
    (int) 1 => [
        '_joinData' => [
            'id' => '',
            'order_id' => '',
            'exception_id' => '1',
            'weft' => '100',
            'warp' => '100',
            'manufacture_name' => 'AC',
            'real_cost' => '1.2',
            'ordered_quantity' => '111',
            'received_quantity' => '1',
            'difference' => '0'
        ],
        'id' => '1772'
    ]
]

修补实体后，我得到了 （我已删除了无用或敏感的数据）

'products' => [
    (int) 0 => object(App\Model\Entity\Product) {

        'id' => (int) 1772,
        '_joinData' => object(App\Model\Entity\OrdersProduct) {
            'id' => (int) 50,
            'exception_id' => null,
            'manufacture_id' => null,
            'order_id' => null,
            'product_id' => (int) 1772,
            'sorting' => (int) 1,
            'price' => null,
            'real_cost' => (float) 1.2,
            'ordered_quantity' => (int) 32,
            'received_quantity' => (int) 2,
            'weft' => (float) 100,
            'warp' => (float) 100,
            'weft_with_shrinkage' => null,
            'warp_with_shrinkage' => null,
            'weft_with_shrinkage_fold' => null,
            'warp_with_shrinkage_fold' => null,
            '[new]' => false,
        },
    }
],

这对我不好。我的客户希望多次添加相同的产品。

有没有一种方法可以防止patchEntity（）删除重复项？
