如何将条件“LIKE？％something％”添加到此联接的产品标题中

Question

Product.find(:all,
    :conditions => { :companies => { :malls => { :id => 1},:products => {:title => "nexus one"} }},
    :joins => [:company => :mall])

Answer 1

我找到了解决方案，我想我必须休息一下，

Product.find(:all,:conditions => ['title LIKE ? and mall_id = ?', "%#{search}%",mall_id],
        :joins => [:company => :mall])
