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

  get "store/index"

  resources :products

  # The priority is based upon order of creation:

  # first created -> highest priority.

  # Sample of regular route:

  #   match 'products/:id' => 'catalog#view'

  # Keep in mind you can assign values other than :controller and :action

  # Sample of named route:

  #   match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase

  # This route can be invoked with purchase_url(:id => product.id)

  # Sample resource route (maps HTTP verbs to controller actions automatically):

  #   resources :products

  # Sample resource route with options:

  #   resources :products do

  #     member do

  #       get 'short'

  #       post 'toggle'

  #     end

  #

  #     collection do

  #       get 'sold'

  #     end

  #   end

  # Sample resource route with sub-resources:

  #   resources :products do

  #     resources :comments, :sales

  #     resource :seller

  #   end

  # Sample resource route with more complex sub-resources

  #   resources :products do

  #     resources :comments

  #     resources :sales do

  #       get 'recent', :on => :collection

  #     end

  #   end

  # Sample resource route within a namespace:

  #   namespace :admin do

  #     # Directs /admin/products/* to Admin::ProductsController

  #     # (app/controllers/admin/products_controller.rb)

  #     resources :products

  #   end

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

  # just remember to delete public/index.html.

  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.order(:title)

  end

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>

    <%= sanitize(product.description) %>

    <div class="price_line">

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

    </div>

  </div>

<% end %>

Show our first (ugly) catalog page

get /
