ActionView :: Template :: Error（缺少属性：col1）

Question

查看：

<%= link_to "Link", {:action => "AjaxView",:col => "colname"}, :update => "Ajaxcall", :remote => true %>

控制器：

def AjaxView
   @vars= Var.find(:all,:conditions => { :varName=> "one" },:select=>(params[:col]))
   respond_to do |format|
      format.js { render :layout=>false }
  end
end

AjaxView.js

$("#3").text("<%= escape_javascript(render(:partial => "var", :collection => @vars)) %>");

_var.html.erb

<%= var.col1 %>

我收到以下错误： ActionView :: Template :: Error（缺少属性：col1）：     1：＆lt;％= var.col1％＆gt;

Answer 1

 <%= @var[0].col %> is the right answer
