module ApplicationHelper
def sortable(column, title = nil)
title ||= column
css_class = column == sort_column ? "current #{sort_direction}" : nil
direction = column == sort_column && sort_direction == "asc" ? "desc" : "asc"
sort_arrow = ""
if(column == sort_column)
if(direction == "desc")
sort_arrow = "▼"
elsif(direction == "asc")
sort_arrow = "▲"
end
end
link_to sort_arrow+title, {:sort => column, :direction => direction,
:search_form => @search_form.attributes
}, {:class => css_class}
end
end
以上是我想测试的方法，问题是sort_column方法在控制器上，因此我收到错误消息method does not exist。如何摆脱它或如何让Controller执行该方法？
编辑： 控制器：
class ResultsController < ApplicationController
def sort_column
params[:sort] != nil ? params[:sort] : 'ID'
end
end
