我有一个名为mac的字段,我存储mac地址,但我需要它是唯一的,以避免重复的mac地址。
代码:
return [
'user_id' => 'required|integer',
'mac' => array('required|unique:mac', 'regex:/^([0-9A-Z]{2}[-]){5}([0-9A-Z]{1,2})$/'),
];
错误: 方法[validateRequired | unique]不存在。
结构:
CREATE TABLE `devices` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`user_id` int(10) unsigned NOT NULL,
`name` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`mac` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`content` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`status` tinyint(1) NOT NULL DEFAULT '0',
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL,
`deleted_at` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `devices_mac_unique` (`mac`),
KEY `devices_user_id_foreign` (`user_id`),
CONSTRAINT `devices_user_id_foreign` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`) ON DELETE CASCADE
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

您需要定义需要根据
检查mac地址的表return [
'user_id' => 'required|integer',
'mac' => 'required|unique:devices,mac|regex:/^([0-9A-Z]{2}[-]){5}([0-9A-Z]{1,2})$/',
];
更新 - 更新记录时,您可以将规则扩展到。
return [
'user_id' => 'required|integer',
'mac' => 'required|unique:devices,mac,' . $device->id . '|regex:/^([0-9A-Z]{2}[-]){5}([0-9A-Z]{1,2})$/',
];
