SearchLogic 是基于 Ruby ActiveRecord 的搜索、分页、排序等操作的类库。
安装方法：sudo gem install searchlogic
一个简单的搜索示例代码：
User.all(
:conditions => {
:first_name_contains => "Ben", # first_name like '%Ben%'
:email_ends_with => "binarylogic.com", # email like '%binarylogic.com'
:created_after => Time.now, # created_at > Time.now
:hour_of_created_at => 5 # HOUR(created_at) > 5 (depends on DB type)
},
:per_page => 20, # limit 20
:page => 3, # offset 40, which starts us on page 3
:order_as => "ASC",
:order_by => {:user_group => :name} # order user_groups.name ASC
)

[color=red][b]发现还有人在看这个博客，这个 SearchLogic 只支持 Rails 2。Rails 3 有一个类似的插件叫 meta search，后来 meta search 又被重新改写，并改名叫 ransack，功能跟 searchlogic 非常相似，如果你在用 Rails 3，推荐使用 ransack。[/b][/color] [b]参考：[url]http://git
