Mysql2 :: Error:您的SQL语法有错误 [英] Mysql2::Error: You have an error in your SQL syntax

问题描述

我只是使用 this 来将我的Rails应用程序数据库从sqlite3切换到mysql2，这似乎可以正常工作.

I just used this to switch my rails app db from sqlite3 to mysql2 and that seemed to work out properly.

但是，当我启动我的应用程序时，我现在得到这个:

But when I start up my app I'm now getting this:

A ActionView::Template::Error occurred in pages#dashboard:

Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '== 1) LIMIT 20 OFFSET 0' at line 1: SELECT `tickets`.* FROM `tickets` WHERE (archived == 1) LIMIT 20 OFFSET 0
activerecord (3.0.3) lib/active_record/connection_adapters/abstract_adapter.rb:202:in `log'

不确定如何定位才能正常工作.任何帮助，将不胜感激.谢谢！

Not sure where to look to get this working properly. Any help would be appreciated. Thanks!

推荐答案

尝试一下:

# Notice single = vs ==
WHERE (archived = 1)

更新 最终做了

Update Ended up doing

scope :is_archived, where('archived != ?', 1)
scope :not_archived, where('archived = ?', 1)

效果很好.谢谢！
