CakePHP 3：关联属性名称与表的同名字段冲突

Question

我正在使用 CakePHP 3.2。我有两张桌子service_requests和coupon_history

service_requests 桌子

CREATE TABLE `service_requests` (
  `id` char(36) NOT NULL,
  `request_id` bigint(20) NOT NULL,
  `user_id` char(36) NOT NULL,
  `user_address_id` char(36) NOT NULL,
  `service_id` char(36) NOT NULL,
  `service_area_id` char(36) NOT NULL,
  `coupon_used` int(11) NOT NULL DEFAULT '0' COMMENT '0: Not Applied; 1: Applied',
  `coupon_used_id` char(36) NOT NULL,
  `status_code` int(11) NOT NULL,
  `status` varchar(50) NOT NULL,
  `created` datetime NOT NULL,
  `modified` datetime NOT NULL
)

coupon_history 桌子

CREATE TABLE `coupon_history` (
  `id` char(36) NOT NULL,
  `user_id` char(36) NOT NULL,
  `coupon_id` char(36) NOT NULL,
  `service_request_id` char(36) DEFAULT NULL,
  `created` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `modified` datetime NOT NULL
)

当我烤service_requests桌子时

bin/cake bake all service_requests

它警告错误为

Association property name "coupon_used" clashes with field of same name of table "service_requests". You should explicitly specify the "propertyName" option. in [/var/www/html/flitfix/admin2/vendor/cakephp/cakephp/src/ORM/Association.php, line 445]

以前有一个coupon_used表，我重命名coupon_history并删除了所有已controller, model and template命名的表coupon_used并尝试再次烘烤，coupon_history但它给出了错误。我尝试了一个由作曲家创建的新项目，但也存在同样的错误。

正如警告所说，字段名称“coupon_used”与coupon_useds表属性之间存在冲突，即coupon_used。这是因为 CakePHP 的默认规则。

您应该在 service_requests 表模型中使用另一个名称更改字段名称“coupon_used”或 coupun_useds 表属性。

class ServiceRequests extends Table{
   ....
   //assumption if association is belongsTo
   $this->belongsTo('CouponUsed',['propertyName' => 'AnotherCouponUsed']);
   ....
}
