simplifyyour life


Develop faster• Each line of code has a cost

– To write the line– To test it– To maintain it

• Write less code– Architecture : controller, ORM, …– Configuration– Autoloading– Generators– Helpers

• More time for business rules, edge cases, …

less code

less complexity

less bugs

more productivity

Main selling points• Documentation• Configurability• XSS protection• Debugging tools• Functional tests• Extensibility : Plugins• Admin Generator• ORM : Propel or Doctrine• i18n / l10n• 1.0 maintained for a long time

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

• 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 } created_at: ~

Environmentsupport

SQL abstraction


Database• Test data # data/fixtures/data.yml Author: fabien: first_name: Fabien last_name: Potencier Post: first_post: author_id: fabien title: PHP Québec

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

1) Creates model classes2) Converts schema to SQL3) Creates tables4) Loads test data


Model// lib/model/Author.phpclass 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());

ORMObject Relationship Mapping

Propel / Doctrine


Backend creation• Automatic creation of an Administration Backend,

ready for production– Lists– Pagination– Tri

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

1) Creates a post module2) Generates configuration

Generated code is MVCand customizableConfiguration file

– Filters– Validation– CRUD


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

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

• Template customization

Generatedmodule

_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: /

/blog/1.html

/

homepage:

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

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

/

/recent


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

$ ./symfony test-functional frontend# get /ok 1 - status code is 200not ok 2 - response selector h1 does not match regex /PHP Québec/# Looks like you failed 1 tests of 21..2

TDDTest Driven Development

CSS Selector


Our first line of code# apps/frontend/modules/blog/actions/actions.class.phpclass 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>
