Question

I integrating of bundles FOSRestBundle,JMSSerializerBundle and NelmioApiDocBundle, I modified the files config.yml and routing.yml but I find this problem
code config.yml:
imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: services.yml }
- { resource: "#UserBundle/Resources/config/services.yml" }
# Put parameters here that don't need to change on each machine where the app is deployed

# if using pdo_sqlite as your database driver:
# 1. add the path in parameters.yml
# e.g. database_path: "%kernel.root_dir%/data/data.db3"
# 2. Uncomment database_path in parameters.yml.dist
# 3. Uncomment next line:
# path: "%database_path%"

prefix: /
app:
resource: "#AppBundle/Controller/"
type: annotation
fos_user:

NelmioApiDocBundle:
resource: "#NelmioApiDocBundle/Resources/config/routing.yml"
prefix: /api/doc
app_api:
resource: "#MedBundle/Resources/config/routing_rest.yml"
type: rest
prefix: /api
code routing_rest.yml:
api_app:
resource: MedBundle\Controller\Api\AppController
type: rest
code AppController.php:
<?php
namespace test\MedBundle\Controller\Api;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use FOS\RestBundle\Controller\Annotations\RouteResource;
/**
* #RouteResource("User")
*/
Class AppController extends Controller {
public function getAction() {
$em = $this->getDoctrine()->getManager();
$test = $em->getRepository('MedBundle:Apps')->findAll();
return array("test" => $test);
}
public function postAction(Request $request){
return $request->request->all();
}
}
Now I find this problem when it can test API
What is the solution and thank you

You don't have any configuration for assetic in your config.yml file. I assume you don't have the AsseticBundle installed on your app. Since Symfony 2.8, Assetic is no longer included by default in the Symfony Standard Edition. You need to install it yourself:
First require the bundle with composer:
composer require symfony/assetic-bundle
Enable the bundle in the AppKernel.php file
class AppKernel extends Kernel
{
// ...
public function registerBundles()
{
$bundles = array(
// ...
new Symfony\Bundle\AsseticBundle\AsseticBundle(),
);
// ...
}
}
add the following minimal configuration to your config.yml file to enable Assetic
# app/config/config.yml
assetic:
debug: '%kernel.debug%'
use_controller: '%kernel.debug%'
