8.2 Iteration C2: Add a Page Layout 7.3 Playtime

Show the model, view, and controller working together.

Create a second controller with a single index action

rails generate controller store index

      create  app/controllers/store_controller.rb

       route  get "store/index"

      invoke  erb

      create    app/views/store

      create    app/views/store/index.html.erb

      invoke  test_unit

      create    test/functional/store_controller_test.rb

      invoke  helper

      create    app/helpers/store_helper.rb

      invoke    test_unit

      create      test/unit/helpers/store_helper_test.rb

Route the 'root' of the site to the store

edit config/routes.rb

Depot::Application.routes.draw do |map|

  get "store/index"

  resources :products

  # ...

  # You can have the root of your site routed with "root"

  # just remember to delete public/index.html.

  # root :to => "welcome#index"

  root :to => 'store#index', :as => 'store'

  # ...

end

Delete public/index.html, as instructed.

rm public/index.html

Demonstrate that everything is wired together

get /

In the controller, get a list of products from the model

edit app/controllers/store_controller.rb

class StoreController < ApplicationController

  def index

    @products = Product.all

  end

end

In the model, define a default sort order

edit app/models/product.rb

class Product < ActiveRecord::Base

  default_scope order('title')

  # validation stuff...

end

In the view, display a list of products

edit app/views/store/index.html.erb

<% if notice %>

<p id="notice"><%= notice %></p>

<% end %>

<h1>Your Pragmatic Catalog</h1>

<% @products.each do |product| %>

  <div class="entry">

    <%= image_tag(product.image_url) %>

    <h3><%= product.title %></h3>

    <%=raw product.description %>

    <div class="price_line">

      <span class="price"><%= product.price %></span>

    </div>

  </div>

<% end %>

Show our first (ugly) catalog page

Debug It!

Professional programmers develop a knack of unerringly zeroing in on the root cause of a bug. They can do that because they've written a lot of buggy code and then gained experience fixing it. This book captures all this experience -- use it, and you'll find you write fewer bugs, and the ones you do write will become easier to hunt down.
