Symfony2: how to override core template?

Question

I am trying to override SymfonyGeneratorBundle templates by creating

\app\Resources\SensioGeneratorBundle\skeleton\crud\views\index.html.twig

That file should replace:

\vendor\bundles\Sensio\Bundle\GeneratorBundle\Resources\skeleton\crud\views\index.html.twig

But it still uses original file even after cache:clear. How to do that w/o creating new bundle like Can't override the standard skeleton views in Symfony2 GeneratorBundle?

Answer 1

Register your bundle right after SensioGeneratorBundle in app/AppKernel.php e.g.:

// app/AppKernel.php

if (in_array($this->getEnvironment(), array('dev', 'test'))) {
    //.....
    $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
    $bundles[] = new Namespace\YourBundle();
}

// Or outside if, should you want your bundle to be available in production environment
$bundles[] = new Namespace\YourBundle();

Then in YourBundle.php override registerCommands method,

// Bundle\YourBundle.php

// other declarations
use Symfony\Component\Console\Application;
use Sensio\Bundle\GeneratorBundle\Generator\DoctrineCrudGenerator;
use Symfony\Component\Filesystem\Filesystem;


public function registerCommands(Application $application){
    $crudCommand = $application->get('generate:doctrine:crud');
    $generator = new DoctrineCrudGenerator(new FileSystem, __DIR__.'/Resources/skeleton/crud');
    $crudCommand->setGenerator($generator);

    parent::registerCommands($application);
}

You have to copy skeleton folder to YourBundle\Resource and modify templates.
