Getting Started With Rails Guide (Step 6) - Routing Error

rubyonrails-talk
1

Hello,

I’ve been trying to solve this issue for a few hours and couldn’t find similar issues by googling. I am very new to Rails. After completing all the steps of “6 Adding a Second Model”, I run into the following error at localhost:3000/articles/1/comments

Routing Error

undefined local variable or method ` ’ for CommentsController:Class

app/controllers/comments_controller.rb:7:in `class:CommentsController’

[app/controllers/comments_controller.rb:1:in `<top (required)>'](http://localhost:3000/articles/5/comments#)



The error occurs after clicking "Create Comment". I triple checked the guide to ensure I copy and pasted everything properly and followed every step but I still cannot figure it out. Since this appears to be a routing issue I pasted all code relevant to routing below. Hopefully I've provided enough information. Thank you.



routes.rb

Rails.application.routes.draw do

  resources :articles do
    resources :comments
  end

  get 'articles/index'
  get 'welcome/index'
  root 'welcome#index'

end

show.html.erb

Title: <%= @article.title %>

Text: <%= @article.text %>

Comments

<% @article.comments.each do |comment| %>

Commenter: <%= comment.commenter %>

Comment: <%= comment.body %>

<% end %>

Add a comment:

<%= form_for([@article, @article.comments.build]) do |f| %>

<%= f.label :commenter %>
<%= f.text_field :commenter %>

<%= f.label :body %>
<%= f.text_area :body %>

<%= f.submit %>

<% end %>

<%= link_to ‘Edit’, edit_article_path(@article) %> | <%= link_to ‘Back’, articles_path %>
