Identifier "twig.loader.filesystem" does not contain an object definition.

[germain-italic]

Hi! Fresh install with Silex-Skeleton, composer edited to require Doctrine DBAL and CRUDlex (which implies more recent versions of twig-bridge and translation):

"require": {
        "php": ">=5.5.9",
        "silex/silex": "~2.0",
        "silex/web-profiler": "~2.0",
        "symfony/asset": "~2.8|3.0.*",
        "symfony/browser-kit": "~2.8|3.0.*",
        "symfony/class-loader": "~2.8|3.0.*",
        "symfony/config": "~2.8|3.0.*",
        "symfony/console": "~2.8|3.0.*",
        "symfony/css-selector": "~2.8|3.0.*",
        "symfony/debug": "~2.8|3.0.*",
        "symfony/finder": "~2.8|3.0.*",
        "symfony/form": "~2.8|3.0.*",
        "symfony/monolog-bridge": "~2.8|3.0.*",
        "symfony/process": "~2.8|3.0.*",
        "symfony/security": "~2.8|3.0.*",
        "symfony/translation": "3.1.*",
        "symfony/twig-bridge": "~3.1",
        "symfony/validator": "~2.8|3.0.*",
        "doctrine/dbal": "~2.2"
    },

Doctrine and Web Profiler working fine.

Adding CRUDlex:

        "philiplb/crudlex": "0.10.x-dev"

Instanciating the MySQLDataFactory, ServiceProvider: OK

Mounting the ControllerProvider results in this error:

InvalidArgumentException in Container.php line 233:
Identifier "twig.loader.filesystem" does not contain an object definition.

I've tried to tweak the Twig instanciation, with no result. However when I comment the Web Profiler instanciation:

$app->register(new WebProfilerServiceProvider(), array(
    'profiler.cache_dir' => __DIR__.'/../var/cache/profiler',
));

Then the error disappears and I can use CRUDlex.

So, it looks like issue #41 is back with the latest version.

Any idea?

Hi, I had to add the LocaleServiceProvider to make it work again. I just adjusted the manual to it. This is what I ended up with:

    return $app->redirect($app['url_generator']->generate('crudList', array('entity' => 'library')));

$app->run();

Thanks for your help, after several tries I managed to make it work.

I had to move

$app->register(new Silex\Provider\WebProfilerServiceProvider(), array(
    'profiler.cache_dir' => __DIR__.'/../var/cache/profiler',
));

between CRUDlex registration and routes mounting. Then I had to add a namespace to my own templates:

$app['twig.loader.filesystem']->addPath(__DIR__.'/../templates', 'app');

I don't understand why those errors happen with 0.10, because I've been using the same project boilerplate for months (with 0.9). Probably related to other Silex dependencies I guess.

[philiplb]

I guess there where some changes from Silex 1.x to Silex 2 causing this, not 100% sure.

[Wirone]

@philiplb you need to extend twig.loader.filesystem like this:

// Silex 1.3
$app['twig.loader.filesystem'] = $app->share($app->extend('twig.loader.filesystem', function($twigLoader, $app) {
    $twigLoader->addPath(__DIR__.'/../templates', 'app');

    return $twigLoader;
}));

// Silex 2.0
$app->extend('twig.loader.filesystem', function($twigLoader, $app) {
    $twigLoader->addPath(__DIR__.'/../templates', 'app');

    return $twigLoader;
});

because $app['twig.loader.filesystem']->addPath() initializes the service and somehow it's not available anymore in Pimple container (for extending, which WebProfilerServiceProvider is trying to do).

[philiplb]

Fixed in https://github.com/philiplb/CRUDlex/commit/10a356a29a9337a97ddb45330cac782a398b2887

Hi,

I would like to reopen this issue because the probleme seems not to be solved.

I work with Silex/Skeleton from Fabien Potencier and when I add Crudlex, there is an error on Twig.

Identifier "twig" does not contain an object definition.

Here, is my app.php :

<?php
use Silex\Application;
use Silex\Provider\AssetServiceProvider;
use Silex\Provider\TwigServiceProvider;
use Silex\Provider\ServiceControllerServiceProvider;
use Silex\Provider\HttpFragmentServiceProvider;

$app = new Application();
$app->register(new ServiceControllerServiceProvider());
$app->register(new AssetServiceProvider());
$app->register(new TwigServiceProvider());
$app->register(new HttpFragmentServiceProvider());

// Doctrine
$app->register(new Silex\Provider\DoctrineServiceProvider(), array(
    'dbs.options' => array(
        'default' => array( )
    )
));

// Locale
$app->register(new Silex\Provider\LocaleServiceProvider());
$app->register(new \Silex\Provider\TranslationServiceProvider(), array(
    'locale_fallbacks' => array('en'),
));

// Crudlex
$dataFactory = new CRUDlex\MySQLDataFactory($app['db']);
$app->register(new CRUDlex\ServiceProvider(), array(
    'crud.file' => __DIR__ . '/../config/crud.yml',
    'crud.datafactory' => $dataFactory
));

// Twig own extension
$app['twig'] = $app->extend('twig', function ($twig, $app) {
    // here, it's work fine
    return $twig;
});

return $app;

If I comment code in the method "registerTwigExtensions" Crudlex\TwigExtensions, it's works (we have Twig errors but everything seems OK)

The container has the Twig object, but we don't pass the validation on extends method in Pimple :

<?php
if (!is_object($this->values[$id]) || !method_exists($this->values[$id], '__invoke')) {
    throw new \InvalidArgumentException(sprintf('Identifier "%s" does not contain an object definition.', $id));
}

is_object ==> ok method_exists ==> ko, because __invoke is not present in object which is a instance of Twig_Environment

If I comment Webprofiler Service Provider, it's work great.

Any ideas ?

[Wirone]

@acidline @philiplb it's because twig.loader.filesystem is not extended with closure, but called directly in ServiceProvider. Again.

[mamoot64]

@Wirone Thank's for your answer, I did not look at this side because it's normaly fixed by the commit 10a356a

Now I have a probleme with the Translator Service Provider...

Identifier "translator" does not contain an object definition

If I deactivate Crudlex, everything work's fine !

Here is my composer.json :

"require": {
        "php": ">=5.5.9",
        "silex/silex": "~2.0",
        "silex/web-profiler": "~2.0",
        "symfony/asset": "3.*",
        "symfony/browser-kit": "3.*",
        "symfony/class-loader": "3.*",
        "symfony/config": "3.*",
        "symfony/console": "3.*",
        "symfony/css-selector": "3.*",
        "symfony/debug": "3.*",
        "symfony/finder": "3.*",
        "symfony/form": "3.*",
        "symfony/monolog-bridge": "3.*",
        "symfony/process": "3.*",
        "symfony/security": "3.*",
        "symfony/translation": "^3.2",
        "symfony/twig-bridge": "3.*",
        "symfony/validator": "3.*",
    "philiplb/crudlex": "0.11.x-dev as 0.10.0",
        "doctrine/migrations": "v1.2.2",
        "kurl/silex-doctrine-migrations-provider": "^0.2.1",
        "philiplb/crudlexuser": "0.12.x-dev"
    }

[Wirone]

@acidline it's because translator service is not properly extended too.

[philiplb]

Both is fixed and pushed, thank you for reporting.

[mamoot64]

Sorry @philiplb, @Wirone, but the problem persists...

According to the Silex doc a better refactoring would be :

    protected function initLocales(Container $app) {

        $locales = $this->getLocales();

        $app->extend('translator', function(Translator $translator) use($locales) {
            $translator->addLoader('yaml', new YamlFileLoader());
            foreach ($locales as $locale) {
                $translator->addResource('yaml', __DIR__.'/../locales/'.$locale.'.yml', $locale);
            }
            return $translator;
        });

        return $locales;
    }

But I always have the problem...

Identifier "translator" does not contain an object definition.

Here is the stack trace :

1. in Container.php line 233
2. at Container->extend('translator', object(Closure)) in WebProfilerServiceProvider.php line 235
3. at WebProfilerServiceProvider->register(object(Application)) in Container.php line 274
4. at Container->register(object(WebProfilerServiceProvider), array('profiler.cache_dir' => '/home/nicolas/Documents/DEVELOPPEMENT/drivehome/drive/config/../var/cache/profiler')) in Application.php line 90
5. at Application->register(object(WebProfilerServiceProvider), array('profiler.cache_dir' => '/home/nicolas/Documents/DEVELOPPEMENT/drivehome/drive/config/../var/cache/profiler')) in dev.php line 17
6. at require('/home/nicolas/Documents/DEVELOPPEMENT/drivehome/drive/config/dev.php') in index_dev.php line 19

[philiplb]

Hi, your refactoring makes totally sense, thank you. I pushed it. Does this solve the problem for you? If not, can you post a minimal dev.php reproducing this behaviour?

[mamoot64]

@philiplb Here is my files structure :

[philiplb]

I moved the initialization of twig and the translator to the boot phase of the service provider. Does that fix the problem for you? My local tests are positive, for me it works both ways, either having the other providers registered in my index.php or not.

[philiplb]

I assume all is good. Just reopen if not. :)
