Question

我的received_po_details表有3个主键receive_po_id，product_id，product_serial。有时，product_serial有价值，有时没有

如果product_serial为空，

cakephp3不允许我插入记录

错误

无法插入行，缺少部分主键值。拿到（12,1，），期待（received_po_id，product_id，product_serial）

sql table

CREATE TABLE IF NOT EXISTS `received_po_details` (
  `received_po_id` int(11) NOT NULL,
  `product_id` int(11) NOT NULL,
  `quantity_received` int(11) NOT NULL,
  `product_serial` varchar(255),
  PRIMARY KEY (received_po_id, product_id, product_serial),
  FOREIGN KEY received_po_key (received_po_id) REFERENCES received_pos(id),
  FOREIGN KEY product_key (product_id) REFERENCES products(id),
  UNIQUE KEY received_po_detail_key (received_po_id, product_id, product_serial)
);

请注意，product_serial只是一个值。它不是外键

entity - receivedPoDetail.php

protected $_accessible = [
    '*' => true,
    'received_po_id' => true,
    'product_id' => true,
    'product_serial' => true,
];

控制器

$receivedPo = $this->ReceivedPos->patchEntity($receivedPo, $this->request->data);

请求数据打印

我认为你应该将product_serial的默认值设置为null 它应该是这样的..

  `product_serial` varchar(255) DEFAULT NULL,

如何在Cakephp3复合主键中插入带空值的记录？
