新手问题 form_for 错误，求指导 [已解决]
大家好，我是新手，目前正跟着 Ruby on Rails Guides 学习，在创建评论表单时出现了如下问题：
这个问题大概是哪里写错了？这个错误是按照这里 [http://guides.rubyonrails.org/getting_started.html#adding-a-second-model] 操作产生的。相对于在 Xcode 中写错字段会报错，Sublime Test2 安静多了啊。
谢谢大家。
6.3 Adding a Route for Comments As with the welcome controller, we will need to add a route so that Rails knows where we would like to navigate to see comments. Open up the config/routes.rb file again, and edit it as follows:
resources :articles do resources :comments end
Rails.application.routes.draw do
get 'welcome/index'
resources :articles do
resources :comments
root 'welcome#index'
end
这样有问题吗？
