    copied!<p>I'm currently learning Ruby on Rails with the help of the Book "Agile Web Development with Rails", but I have a problem with the first application.</p> <p>I created the app with <code>rails new depot</code> and generated the scaffold with </p> <pre><code>rails generate scaffold Product \title:string description:text image_url:string price:decimal </code></pre> <p>Then I ran <code>rake db:migrate</code></p> <p>According to the book I should now be able to create new Products which would then display immediately. But when adding a new Product it does not show up when viewing the url <code>http://localhost:3000/products</code> or <code>http://localhost:3000/products.json</code>, When I view the database file the added products are there.</p> <p>The added Products show up in the list after I restarted the server. Does anybody know what I've done wrong?</p> <p>Using: Rails 3.2.4, Ruby 1.9.3, WEBrick 1.3.1, SQLite 3 and Mac OSX</p> <p>EDIT: Code generated by the scaffold:</p> <pre><code> products_controller.rb # GET /products # GET /products.json def index @products = Product.all respond_to do |format| format.html # index.html.erb format.json { render json: @products } end end index.html.erb &lt;h1&gt;Listing products&lt;/h1&gt; &lt;table&gt; &lt;tr&gt; &lt;th&gt;Title&lt;/th&gt; &lt;th&gt;Description&lt;/th&gt; &lt;th&gt;Image url&lt;/th&gt; &lt;th&gt;Price&lt;/th&gt; &lt;th&gt;&lt;/th&gt; &lt;th&gt;&lt;/th&gt; &lt;th&gt;&lt;/th&gt; &lt;/tr&gt; &lt;% @products.each do |product| %&gt; &lt;tr&gt; &lt;td&gt;&lt;%= product.title %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= product.description %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= product.image_url %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= product.price %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= link_to 'Show', product %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= link_to 'Edit', edit_product_path(product) %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= link_to 'Destroy', product, confirm: 'Are you sure?', method: :delete %&gt;&lt;/td&gt; &lt;/tr&gt; &lt;% end %&gt; &lt;/table&gt; &lt;br /&gt; &lt;%= link_to 'New Product', new_product_path %&gt; </code></pre>
