Hello,
Does anybody ever use
Symfony\Component\DependencyInjection\Dumper\GraphvizDumper in symfony2
application? I tried dump my services from kernel like this:
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
require_once __DIR__.'/../app/AppKernel.php';
use Symfony\Component\DependencyInjection\Dumper\GraphvizDumper;
class MyKernel extends \AppKernel {
//Hack to get ContainerBuilder from Kernel.
public $container_builder = null;
protected function buildContainer() {
$this->container_builder = parent::buildContainer();
return $this->container_builder;
}
}
$kernel = new MyKernel('prod', true);
$kernel->boot();
$cb = $kernel->container_builder;
$dumper = new GraphvizDumper($cb);
echo $dumper->dump();
But I get exception:
ErrorException: Catchable Fatal Error: Argument 1 passed to
Symfony\Component\DependencyInjection\Container::addScope() must implement
interface Symfony\Component\DependencyInjection\ScopeInterface, string
given, called in ...
I wonder if this class is somehow usable? It is tested only with
ContainerBuilder created manually (
Symfony\Component\DependencyInjection\Tests\Dumper\GraphvizDumperTest) . I
couldn't find any documentation how to use it for real application.
Regards
MZak
