Database schema definition
# config/schema.yml
post:
title: { type: varchar, size: 255 }
content: { type: longvarchar }
is_published: { type: boolean }
author_id: { type: integer, foreignTable: author ,
foreignReference: id }

SQL abstraction

Test data
# data/fixtures/data.yml
Author:
fabien :
first_name: Fabien
last_name: Potencier
Post:
first_post:
author_id: fabien
title: Xtech 2007

Generate the thing
$ ./symfony propel-build-all-load frontend
1) Creates model classes 2) Converts schema to SQL 3) Creates tables 4) Loads test data

Model
// lib/model/Author.php
class Author extends BaseAuthor
{
function getFullName()
{
return $this -> getFirstName(). ' ' .$this -> getLastName();
}
}
$author = new Author();
$author -> setFirstName( 'Fabien' );
$author -> setLastName( 'Potencier' );
$author -> save();
$post = new Post();
$post -> setAuthor($author);
$post -> setPublishedOn( '12:00 tomorrow' );
$post -> isPublished( true );
$post -> save();
$posts = PostPeer :: doSelect(new Criteria());
ORM Object Relationship Mapping Propel / Doctrine

Backend creation
Automatic creation of an Administration Backend, ready for production
Lists
Pagination
Sorting
$ ./symfony propel-init-admin frontend post Post
Filters
Validation
CRUD
1) Creates a post module 2) Generates configuration Generated code is MVC and customizable Configuration file Contr oller Templates

Configurability
Module level
# apps/frontend/modules/post/config/generator.yml
generator:
class: sfPropelAdminGenerator
param:
model_class: Post
list :
display: [ =title , author, created_at]
filters : [title, author_id, published_on]
max_per_page: 5
Application level
# apps/frontend/config/security.yml
default:
is_secure: on

$ ./symfony plugin-install http://plugins.symfony-project.com/ sfGuardPlugin
Configuration Framework Project Application Module LOC : 0

Admin Generator – list view

Admin Generator – edit view __toString() widgets m2m relationship

Extensibility
Module extension
class postActions extends autoPostActions
{
protected function addFiltersCriteria($c)
{
parent :: addFiltersCriteria($c);
$c -> add(PostPeer :: IS_PUBLISHED, true );
}
}
Template customization
Generated module _edit_* : actions, footer, form, header, messages _list_* : footer, header, messages, td_actions, t(d|h)_stacked, t(d|h)_tabular _filters, editSuccess, listSuccess

Frontend Creation
Routing
<?php echo link_to( $post -> getTitle(), '@post?id=’ .$post -> getId() ) ?> post : param: { module: blog, action: show } requirements: id: d+ url: /blog/:id.html <?php echo url_for( '@homepage' ) ?> homepage : param: { module: blog, action: recent } url: / homepage : param: { module: blog, action: list } url: / recent : param: { module: blog, action: recent } url: /recent /blog/1.html / / /recent

Functional Tests
Simulate navigation and make smart assertions
// test/functional/frontend/blogActionsTest.php
$browser = new sfTestBrowser();
$browser -> initialize();
$browser ->
get( '/blog/1.html' ) ->
isStatusCode( 200 ) ->
checkResponseElement( 'h1.title' , '/XTech 2007/' );
$ ./symfony test-functional frontend
# get /
ok 1 - status code is 200
not ok 2 - response selector h1 does not match regex /XTech 2007/
# Looks like you failed 1 tests of 2
1..2
TDD Test Driven Development CSS Selector

Our first line of code
# apps/frontend/modules/blog/actions/actions.class.php
class blogActions extends sfActions
{
function executeShow()
{
$id = $this -> getRequestParameter( 'id' );
$this -> post = PostPeer :: retrieveByPk($id);
$this -> forward404Unless($this -> post);
}
}
# apps/frontend/modules/post/templates/showSuccess.php
<h1 class= "title" ><?php echo $post -> getTitle() ?></h1>
<h2>par <?php echo $post -> getAuthor() -> getFullName() ?></h2>
<p><?php echo $post -> getHtmlContent(ESC_RAW) ?></p>
