编辑：

的routes.rb

resources :friendships, :except => [:new, :edit, :update, :index, :show]

正在运行rake:routes

                 friendships POST   /friendships(.:format)                          friendships#create
                  friendship DELETE /friendships/:id(.:format)                      friendships#destroy

替换：

friendships_path(:friend_id => @user)

使用：

friendship_path(:id => @user)
