Symfony2 caching issue
Question
I'm trying to create a "Hello World" with Symfony2 and it seemed to run the first time, but whatever changes I do and save the controller - no changes on the front end whatsoever.
This is how my controller looks like:
namespace Test\CalcBundle\Controller;
use Symfony\Component\HttpFoundation\Response;
class CalcController {
public function indexAction($name) {
return new Response("<html><body>Hello " . $name . "!</body></html>");
}
}
No matter how I change this file - nothing reflects in the browser. Is this some kind of caching going on and if so how do I disable it? Browser is not caching it, because if I change the last bit of the url - it reflects on the page.
I'm running this in my development environment - Windows 8, PHP 5.5.3 (XAMPP), Apache.
UPDATE: Sorry, forgot to add, the URL I'm using is this:
http://localhost/test/web/app_dev.php/Calc/name
UPDATE2: app/config/routing.yml:
test_calc:
resource: "@TestCalcBundle/Resources/config/routing.yml"
prefix: /
src/Test/CalcBundle/Resources/config/routing.yml:
test_calc_homepage:
pattern: /Calc/{name}
defaults: { _controller: TestCalcBundle:Default:index }
UPDATE3: The exact version of Symfony2 I'm using is 2.3.5
UPDATE4: Found the reason - somehow DefaultController is being used instead of the one I've created... How do I fix that?
UPDATE5: I managed to solve the problem, although I don't know whether it's a good way to do that. I've changed the src/Test/CalcBundle/Resources/config/routing.yml to look like this:
test_calc_homepage:
pattern: /Calc/{name}
defaults: { _controller: TestCalcBundle:Calc:index }
UPDATE6: Solved - the problem was default controller left in routing.yml due to lack of understanding.

Symfony has two access points to the application in the web dir
-
web/app.php(this is for production the cache is active) -
web/app_dev.php(this is for dev the cache changes when you change something like templates, etc.)
point your browser to http://localhost/app_dev.php
you can get more information about environments in Creating Pages in Symfony 2
you can check if your files are correct
app.php
<?php
use Symfony\Component\ClassLoader\ApcClassLoader;
use Symfony\Component\HttpFoundation\Request;
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
// Use APC for autoloading to improve performance.
// Change 'sf2' to a unique prefix in order to prevent cache key conflicts
// with other applications also using APC.
/*
$loader = new ApcClassLoader('sf2', $loader);
$loader->register(true);
*/
require_once __DIR__.'/../app/AppKernel.php';
//require_once __DIR__.'/../app/AppCache.php';
$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
//$kernel = new AppCache($kernel);
Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
app_dev.php
<?php
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Debug\Debug;
// If you don't want to setup permissions the proper way, just uncomment the following PHP line
// read http://symfony.com/doc/current/book/installation.html#configuration-and-setup for more information
//umask(0000);
// This check prevents access to debug front controllers that are deployed by accident to production servers.
// Feel free to remove this, extend it, or make something more sophisticated.
if (isset($_SERVER['HTTP_CLIENT_IP'])
|| isset($_SERVER['HTTP_X_FORWARDED_FOR'])
|| !in_array(@$_SERVER['REMOTE_ADDR'], array('127.0.0.1', 'fe80::1', '::1'))
) {
header('HTTP/1.0 403 Forbidden');
exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
}
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
Debug::enable();
require_once __DIR__.'/../app/AppKernel.php';
$kernel = new AppKernel('dev', true);
$kernel->loadClassCache();
Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
that are the files are have with sf 2.3.4
the projects with sf 2.3.* need the Debug::enable(); line, check that line exists in your file
