錯誤：SQLSTATE [42S22]：未找到列：1054 CakePHP

Question

我一直在尋找一些答案，當我試圖訪問CakePHP的一個頁面，並且我仍然收到這個錯誤時發生的問題：

錯誤：SQLSTATE [42S22]：未找到列：1054未知列'方坯。 USER_ID」在‘字段列表’

這裏是由蛋糕創建的查詢

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 

，做查詢直接由蛋糕出爐，所以我沒有任何線顯示查詢如何的做了代碼。

Answer 1

你錯過蜱在這條線上，你必須在AS名的額外空間：

`Billet. user_id` AS `Billet__ user_id`, 

應該

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

同去的這條線：

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

這應該是

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