• Database configuration
# config/databases.yml
prod: Environment
propel:
support
param:
password: PAssWD
all:
propel:
class: sfPropelDatabase
param:
dsn: mysql://root:@localhost/sfdemo

• Schema definition SQL abstraction
# config/schema.yml
post:
title: { type: varchar, size: 255 }
content: { type: longvarchar }
is_published: { type: boolean }
author_id: { type: integer, foreignTable: author, foreignReference: id }
created_at: ~

Database
• Test data
# data/fixtures/data.yml
Author:
fabien:
first_name: Fabien
last_name: Potencier
Post: 1) Creates model classes
first_post: 2) Converts schema to SQL
author_id: fabien 3) Creates tables
title: PHP Québec 4) Loads test data

$ ./symfony propel-build-all-load frontend


Model
// lib/model/Author.php
class Author extends BaseAuthor
{
function getFullName()
{
return $this->getFirstName().' '.$this->getLastName();
}
}

$author = new Author();
$author->setFirstName('Fabien'); ORM
$author->setLastName('Potencier'); Object Relationship Mapping
$author->save();
Propel / Doctrine
$post = new Post();
$post->setAuthor($author);
$post->setPublishedOn('12:00 tomorrow');
$post->isPublished(true);
$post->save();

$posts = PostPeer::doSelect(new Criteria());


Backend creation
• Automatic creation of an Administration Backend,
ready for production
– Lists – Filters Generated code is MVC
and customizable
– Pagination – Validation Configuration file
Controller
– Tri – CRUD Templates

$ ./symfony propel-init-admin frontend post Post

1) Creates a post module
2) Generates configuration


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

• Application level
# apps/frontend/config/security.yml
default:
is_secure: on
credentials: admin
LOC : 0
$ ./symfony plugin-install http://plugins.symfony-project.com/sfGuardPlugin


Admin Generator
• List


Admin Generator
• Edition

__toString()

widgets m2m relationship


Extensibility
• Module extension
class postActions extends autoPostActions
{
protected function addFiltersCriteria($c) Generated
{ module
parent::addFiltersCriteria($c);
$c->add(PostPeer::IS_PUBLISHED, true);
}
}

• Template customization
_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
homepage:
/ param: { module: blog, action: recent } <?php echo url_for('@homepage') ?>
url: /

homepage:
/ param: { module: blog, action: list }
url: /
recent:
/recent param: { module: blog, action: recent }
url: /recent

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


Functional Tests
• Navigation simulation
// test/functional/frontend/blogActionsTest.php
$browser = new sfTestBrowser();
$browser->initialize(); TDD
$browser-> Test Driven Development
get('/blog/1.html')->
isStatusCode(200)->
checkResponseElement('h1.title', '/PHP Québec/');

$ ./symfony test-functional frontend
CSS Selector
# get /
ok 1 - status code is 200
not ok 2 - response selector h1 does not match regex /PHP Québec/
# Looks like you failed 1 tests of 2
1..2


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); MVC
$this->forward404Unless($this->post); Model / View / Controller
} XSS
} shortcut Secure by default

# 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>
