我正在关注Ryan Bates关于可排序表列的railscast,我已经成功地获得了一个可以升序和降序排序的列。
我的表比Railscast中的表更复杂,因为我有来自不同表的列。
# controller
@cars = Car.find(:all).order(sort_column + " " + sort_direction).includes(:manufacturers)
#view
<%= sortable "age" %>
如何为制造商等相关表添加可排序列?

我也有类似的问题。用类似的东西修复了它:
<%= sortable "manufacturers.name", "Manufacturer name" %>
<%= sortable "cars.age", "Age" %>
application_controller中的排序函数应该如下所示:
def sort_column
[ manufacturers.name , cars.age ].include?(params[:sort]) ? params[:sort] : cars.age
