RESTful routing in Zend 1.x

RESTful routing in Zend 1.x

I am new to Zend Framework and am trying to implement a RESTful controller
in Zend and trying to write unit tests for my controller. I am following
the REST API available at:
https://github.com/codeinchaos/restful-zend-framework but for every kind
of test, PHPUnit always hits 404 (observable by asserting the response
codes - the one I expect and the one that PHPUnit receives), thus failing
the tests.
I have added all code in respective files as this REST API's readme
instructs:
• I have added a module specific for REST: /application/modules/api. • In
my application.ini, I have the following:
autoloaderNamespaces[] = "REST_"
rest.default = "xml"
rest.formats[] = "json"
rest.formats[] = "xml"
resources.frontController.plugins.ErrorHandler.class =
"Zend_Controller_Plugin_ErrorHandler"
resources.frontController.plugins.ErrorHandler.options.module = "default"
resources.frontController.plugins.ErrorHandler.options.controller = "error"
resources.frontController.plugins.ErrorHandler.options.action = "error"
resources.router.routes.rest.type = Zend_Rest_Route
• In my application/bootstrap.php:
public function _initREST()
{
$frontController = Zend_Controller_Front::getInstance();
// set custom request object
$frontController->setRequest(new REST_Request);
$frontController->setResponse(new REST_Response);
$frontController->addModuleDirectory(APPLICATION_PATH . '/modules');
// Add the REST route for the API module only
$restRoute = new Zend_Rest_Route($frontController, array(),
array('api'));
$frontController->getRouter()->addRoute('rest', $restRoute);
}
• In my /application/modules/api/Bootstrap.php:
public function _initREST()
{
$frontController = Zend_Controller_Front::getInstance();
// Register the RestHandler plugin
$frontController->registerPlugin(new
REST_Controller_Plugin_RestHandler($frontController));
// Add REST contextSwitch helper
$contextSwitch = new REST_Controller_Action_Helper_ContextSwitch();
Zend_Controller_Action_HelperBroker::addHelper($contextSwitch);
// Add restContexts helper
$restContexts = new REST_Controller_Action_Helper_RestContexts();
Zend_Controller_Action_HelperBroker::addHelper($restContexts);
}
• Out of my own experiments, I have also added a line
$autoloader->registerNamespace('REST_') to my /public/index.php where
$autoloader refers to an instance of Zend_Loader_Autoloader.
• My test's location:
/tests/application/modules/api/controllers/RestClassTest.php • This is my
one of my tests for getAction():
public function testGetAction()
{
$this->request->setMethod('GET');
// Have tried other variations of URI too but all bear same result
(getting 404) in tests indicating that routing is not set at the
fundamental level.
$this->dispatch('/api/learn-to-rest?id=51fc287fc55ffc4006410bca');
$body = $this->getResponse()->getBody();
$json = json_decode($body, true);
$this->assertEquals('John Doe', $json['name']);
$httpResponse = $this->getResponse()->getHttpResponseCode();
$this->assertEquals(200, $httpResponse);
}
• And this is my getAction():
public function getAction()
{
$request = $this->getRequest();
$objectId = $request->getParam('id');
// Validation for ID
$this->_validateMongoObjectIdAction($objectId);
// Perform DB record selection
$records = new Db_Collection_Class(new Db_Mongo_Class);
$result = $records->findInCollection(array('_id' => new
MongoId($objectId)));
if ($result === null) {
// Source: http://www.w3.org/Protocols/HTTP/HTRESP.html
$this->getResponse()->setHttpResponseCode(404);
}
// Dispatch records in JSON format
$this->_helper->json($result);
}
It is true that I am setting a 404 for no-result-found situation but
confining specifically at getAction, it is hitting 404 with test for a
recognized valid ID as well.
I checked numerous resources (including the example provided by this API
and Matthew O'Phinney's post:
http://www.mwop.net/blog/228-Building-RESTful-Services-with-Zend-Framework.html)
and all instruct to follow the same things that I am already doing. It is
evident that I am missing something they are telling or am not
comprehending some factor. I'll be obliged if anyone guides me where I'm
doing what wrong.
Thanks in advance.
