错误：SQLSTATE [42S22]：找不到列：1054 CakePHP

Question

我一直在寻找一些解决方案，以解决在尝试访问使用 CakePHP 烘焙的页面时出现的问题，但我仍然收到此错误：

错误：SQLSTATE[42S22]：未找到列：1054 未知列 'Billet. '字段列表'中的 user_id'

这是 Cake 创建的查询

SELECT `Billet`.`id` AS `Billet__id`, 
`Billet`.`created` AS `Billet__created`, 
`Billet`.`updated` AS `Billet__updated`, 
`Billet. user_id` AS `Billet__ user_id`,
`Billet`.`title` AS `Billet__title`, 
`Billet`.`tags` AS `Billet__tags`, 
`Billet`.`content` AS   `Billet__content`, 
`Users`.`id` AS `Users__id`, 
`Users`.`username` AS `Users__username`, 
`Users`.`password` AS `Users__password`, 
`Users`.`name` AS `Users__name`,
`Users`.`lastname` AS `Users__lastname`, 
`Users`.`birthdate` AS `Users__birthdate`, 
`Users`.`email` AS `Users__email` FROM `billet`
`Billet` INNER JOIN `users` `Users` ON `Users`.`id` = (`Billet. user_id`) LIMIT 20 OFFSET 0

查询的代码是直接由 Cake 烘焙的，所以我没有任何行来说明查询是如何完成的。

Answer 1

您在这一行缺少刻度，并且您在 AS 名称中有一个额外的空格：

`Billet. user_id` AS `Billet__ user_id`,

应该是

`Billet`.`user_id` AS `Billet__user_id`,

这一行也是如此：

`Billet` INNER JOIN `users` `Users` ON `Users`.`id` = (`Billet. user_id`) LIMIT 20 OFFSET 0

应该是

`Billet` INNER JOIN `users` `Users` ON `Users`.`id` = (`Billet`.`user_id`) LIMIT 20 OFFSET 0
