Generate the thing

$ ./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());

Functional TestsSimulate 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 200not ok 2 - response selector h1 does not match regex /XTech 2007/# Looks like you failed 1 tests of 21..2
