如何让搜索逻辑与Rails3协同工作？

Question

我把搜索逻辑放到了我的文件里...现在我的rails服务器不能启动了:(

这是错误消息

我该如何解决这个问题？提前感谢，干杯tabaluga

Answer 1

github上有支持Rails3的railsdog's searchlogic fork。

您可以将其添加到Gemfile中，如下所示：

gem 'rd_searchlogic', :require => 'searchlogic', :git => 'git://github.com/railsdog/searchlogic.git'

Answer 2

在Rails3中，您可以使用meta_search。

它与搜索逻辑非常相似，但是

<%= order @search, :by => :name, :as => "Order By Name" %>

被更改为

<%= sort_link @search, :name, "Order By Name" %>
