Mysql2 ::错误：您的SQL语法中有错误

Question

我刚刚使用this将我的rails app db从sqlite3切换到mysql2，这似乎可以正常运行。

但是当我启动我的应用程序时，我现在得到了这个：

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'

不确定在哪里可以正常使用。任何帮助，将不胜感激。谢谢！

Answer 1

试试这个：

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

---

<强>更新 结束了

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

这很有效。谢谢！
