原标题:Rails/SQL - How to search for partial match and get results?

这是房地产搜索网站定位搜索域的代码 :

   scope :location, lambda{|l|  where("city LIKE ? OR zip_code LIKE ? OR address LIKE ?", l, l, l)}

但我必须把完整的城市名称或 zip 代码或地址 来获得结果, 我如何修正它才能只搜索两到三个字母或数字, 并获得包含这些字母或数字的结果? 我尝试了这样包起来:% l% but no luck.

最佳回答

尝试此 :

scope :location, lambda{|l|  where("city LIKE :l OR zip_code LIKE :l OR address LIKE :l", l: "%#{l}%")}
