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/controllers/store_controller_test.rb

      invoke  helper

      create    app/helpers/store_helper.rb

      invoke    test_unit

      invoke  assets

      invoke    coffee

      create      app/assets/javascripts/store.coffee

      invoke    scss

      create      app/assets/stylesheets/store.scss

Route the 'root' of the site to the store

edit config/routes.rb

Rails.application.routes.draw do

  get 'store/index'

  resources :products

  # The priority is based upon order of creation:

  # first created -> highest priority.

  # See how all your routes lay out with "rake routes".

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

  root 'store#index', as: 'store'

  # Example of regular route:

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

  # Example of named route that can be invoked with purchase_url(id: product.id)

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

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

  #   resources :products

  # Example resource route with options:

  #   resources :products do

  #     member do

  #       get 'short'

  #       post 'toggle'

  #     end

  #

  #     collection do

  #       get 'sold'

  #     end

  #   end

  # Example resource route with sub-resources:

  #   resources :products do

  #     resources :comments, :sales

  #     resource :seller

  #   end

  # Example resource route with more complex sub-resources:

  #   resources :products do

  #     resources :comments

  #     resources :sales do

  #       get 'recent', on: :collection

  #     end

  #   end

  # Example resource route with concerns:

  #   concern :toggleable do

  #     post 'toggle'

  #   end

  #   resources :posts, concerns: :toggleable

  #   resources :photos, concerns: :toggleable

  # Example resource route within a namespace:

  #   namespace :admin do

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

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

  #     resources :products

  #   end

end

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

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

<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 %>

Add some basic style

edit app/assets/stylesheets/store.scss

// Place all the styles related to the Store controller here.

// They will automatically be included in application.css.

// You can use Sass (SCSS) here: http://sass-lang.com/

.store {

  h1 {

    margin: 0;

    padding-bottom: 0.5em;

    font:  150% sans-serif;

    color: #226;

    border-bottom: 3px dotted #77d;

  }

  /* An entry in the store catalog */

  .entry {

    overflow: auto;

    margin-top: 1em;

    border-bottom: 1px dotted #77d;

    min-height: 100px;

    img {

      width: 80px;

      margin-right: 5px;

      margin-bottom: 5px;

      position: absolute;

    }

    h3 {

      font-size: 120%;

      font-family: sans-serif;

      margin-left: 100px;

      margin-top: 0;

      margin-bottom: 2px;

      color: #227;

    }

    p, div.price_line {

      margin-left: 100px;

      margin-top: 0.5em; 

      margin-bottom: 0.8em; 

    }

    .price {

      color: #44a;

      font-weight: bold;

      margin-right: 3em;

    }

  }

}

CoffeeScript

CoffeeScript is JavaScript done right. It provides all of JavaScript's functionality wrapped in a cleaner, more succinct syntax. In the first book on this exciting new language, CoffeeScript guru Trevor Burnham shows you how to hold onto all the power and flexibility of JavaScript while writing clearer, cleaner, and safer code.
