What is the issue with not overriding templates in symfony2.6 and FOSUserBundle 1.3

问题

I'm trying to override the base layout of FOSUserBundle using the 'simple' option of making a cloned path as .app/Resources/FOSUserBundle/views/layout.html.twig , but symfony2.6 continues to render the template from inside the vendor directory.

My composer requires:

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.6.*",
    "doctrine/orm": "~2.2,>=2.2.3,<2.5",
    "doctrine/dbal": "<2.5",
    "doctrine/doctrine-bundle": "~1.2",
    "twig/extensions": "~1.0",
    "symfony/assetic-bundle": "~2.3",
    "symfony/swiftmailer-bundle": "~2.3",
    "symfony/monolog-bundle": "~2.4",
    "sensio/distribution-bundle": "~3.0,>=3.0.12",
    "sensio/framework-extra-bundle": "~3.0,>=3.0.2",
    "incenteev/composer-parameter-handler": "~2.0",
    "friendsofsymfony/user-bundle": "~1.3"
},

I've checked the following common issues:

filesystem case sensitivity - looks OK
having the correct path - seems OK
clearing the cache: both manually and from the app/console - no problem here

Other information: - runs on a vagrant instance with ubuntu-trusty-64 - the synced folder is through NFS

Any ideas in what I should look or do next ?

回答1:

The problem had mostly nothing to do with Symfony2 or FOSUserBundle, but with the way PHP caches the file stats.

To locate the right template to load, standard Symfony2 uses Symfony\Component\HttpKernel\Kernel->locateResource , by first checking if an override exists in the .app\Resources directory and if the $first parameter is set to true it returns from inside the foreach loop.

In my configuration, PHP decided to keep using the filecache and answer no to file_exists even if the file was there.

To go around / fix this problem my AppKernel.php overrides the locateResource of the Symfony\Component\HttpKernel\Kernel class:

<?php
class AppKernel extends Kernel
{
    // .. other methods here

    public function locateResource($name, $dir = null, $first = true)
    {
        clearstatcache(true);
        return parent::locateResource($name, $dir, $first);
    }
}

Not pretty, but it works.
