  end

  # GET /users/1

  def show
    #@user = User.find(params[:id])

    respond_to do |format|

你正在使用Rails 3的机会很好,对吧？这是一个常见问题.在rails 2.x中,link_to帮助程序用于创建凌乱的内联javascript以创建使用适当delete调用提交的表单(有点,但对于此解释足够好).

然而,在Rails 3中,实际执行此操作的javascript已被移出视图本身,转换为javascript文件.这被称为"不显眼的"javascript,其中HTML源代码严格用于文档结构,文档行为存在于其他地方.

底线是您的布局需要在<head>部分中包含这些文件,如下所示:

<%= javascript_include_tag :all %>
