(undefined method `each' for nil:NilClass) while doing Getting started tutorial

[Med Potter]

I followed every line of the tutorial

but I get this error

Showing /home/ubuntu/blog/app/views/articles/index.html.erb where line #9 raised:

undefined method `each' for nil:NilClass

  <% @articles.each do |article| %>

    <tr>

      <td><%= article.title %></td>

      <td><%= article.text %></td>

if you think that might not have returned the articles in the controller, thats not true :

here is code for my controller :

 

 $ cat app/controllers/articles_controller.rb

class ArticlesController < ApplicationController

def index

    @articles = Article.all

end

and here is code for my view

$ cat  app/views/articles/index.html.erb

<h1>Listing articles</h1>

<table>

  <tr>

    <th>Title</th>

    <th>Text</th>

  </tr>

  <% @articles.each do |article| %>

    <tr>

      <td><%= article.title %></td>

      <td><%= article.text %></td>

    </tr>

  <% end %>

</table>

 

The code works for showing one article but not for showing all articles

http://localhost:3000/articles

2 Possibilities. 

1. Did you run your migrations

2. Did you restart your server after that ?

To check that @articles is ok at this point then insert here
puts @articles.inspect
which will print the contents of @articles in the server terminal window.
