我有2个模型用户(devise gem)和简介。

  class User < ActiveRecord::Base
    has_one :profile

  class Profile < AciveRecord::Base
    belongs_to :user

每一种模式的看法都值得一提,但我想在申请内容上有一个联系。

  <% if user_signed_in? %>
  <li><%= link_to current_user.username , profile_path(@profile) %></li>

但这表明我这一错误:

 ActionController::RoutingError (No route matches {:action=>"show", :controller=>"profiles"})

我的履历

  def show 
  @profile = Profile.find(params[:id])

respond_to do |format|
  format.html # show.html.erb
  format.json { r结束er json: @profile }
结束

结束

我希望这一链接能够显示目前的用户名称(我已经绘制了用户名称),并与当前用户的简介页面链接。
