UPGRADING-2.0.md

Upgrading From 1.x To 2.0

• The RedirectView and RouteRedirect view classes were removed. Use View::createRedirect() and View::createRouteRedirect() instead.

  Note: the default status code for a route redirect has changed from HTTP_CREATED (201) to HTTP_FOUND (302).

• The FOS\RestBundle\Util\ViolationFormatter class and the FOS\RestBundle\Util\ViolationFormatterInterface were removed. Catch specialized exception classes instead of checking specific exception messages.

• The ViolationFormatterInterface argument of the constructor of the ParamFetcher class was removed.

• The SensioFrameworkExtraBundle view annotations must be enabled to use the ViewResponseListener:

  # app/config/config.yml
  sensio_framework_extra:
      view:
          annotations: true

• dropped support for the legacy Symfony\Component\Validator\ValidatorInterface

• removed FOS\RestBundle\Util\Codes in favor of Symfony\Component\HttpFoundation\Response constants

• compatibility with Symfony <2.7, JMS Serializer/SerializerBundle <1.0 and SensioFrameworkExtraBundle <3.0 was dropped

• constructor signature of DisableCSRFExtension was changed

• constructor signatures of most of the classes which used the container were changed

• removed callback_filter configuration option for the jsonp_handler

• removed fos_rest.format_listener.media_type configuration option. Use the versioning section instead:

  # config.yml
  
  versioning: true

• the exception_wrapper_handler config option was removed. Use normalizers instead.

  Before:

  # config.yml
  
  fos_rest:
      view:
          exception_wrapper_handler: AppBundle\ExceptionWrapperHandler

  namespace AppBundle;
  
  class ExceptionWrapperHandler implements ExceptionWrapperHandlerInterface
  {
      public function wrap($data)
      {
          return new ExceptionWrapper(array('status_code' => 'foo'));
      }
  }

  After (if you use the Symfony serializer):

  # services.yml
  
  services:
      app_bundle.exception_normalizer:
          class: AppBundle\Normalizer\ExceptionNormalizer
          tags:
              - { name: serializer.normalizer }

  namespace AppBundle\Normalizer;
  
  use Symfony\Component\Serializer\Normalizer\NormalizerInterface;
  
  class ExceptionNormalizer implements NormalizerInterface
  {
      public function normalize($object, $format = null, array $context = array())
      {
          return array('status_code' => 'foo');
      }
  
      public function supportsNormalization($data, $format = null)
      {
          return $data instanceof \My\Exception;
      }
  }

• removed all .class parameters, instead overwriting services via explicit Bundle configuration is preferred

• renamed AbstractScalarParam::$array to AbstractScalarParam::$map

  Before:

  namespace AppBundle\Controller;
  
  class MyController
  {
      /**
       * @RequestParam(name="foo", array=true)
       */
      public function myAction()
      {
          // ...
      }
  }

  After:

  namespace AppBundle\Controller;
  
  class MyController
  {
      /**
       * @RequestParam(name="foo", map=true)
       */
      public function myAction()
      {
          // ...
      }
  }

• added ControllerTrait for developers that prefer to use DI for their controllers instead of extending FOSRestController

• when having an action called lockUserAction, then it will have to use the http method LOCK (RFC-2518) instead of PATCH. The following methods are affected by this change:

  • COPY
  • LOCK
  • MKCOL
  • MOVE
  • PROPFIND
  • PROPPATCH
  • UNLOCK

• removed the ability of the AccessDeniedListener to render a response. Use the FOSRestBundle or the twig exception controller in complement.

  Before:

  # config.yml
  
  fos_rest:
      access_denied_listener: true

  After:

  # config.yml
  
  fos_rest:
      access_denied_listener: true
      exception: true # Activates the FOSRestBundle exception controller

• changed the priority of RequestBodyParamConverter to -50

• made silent the RequestBodyParamConverter when a parameter is optional and it can't resolve it

• removed the format_negotiator option exception_fallback_format; you can match the ExceptionController thanks to the attributes option instead

  Before:

  # config.yml
  
  fos_rest:
     format_listener:
         rules:
             - { path: ^/, fallback_format: html, exception_fallback_format: json }

  After:

  # config.yml
  
  fos_rest:
     format_listener:
         rules:
             - { path: ^/, fallback_format: json, attributes: { _controller: FOS\RestBundle\Controller\ExceptionController } }
             - { path: ^/, fallback_format: html } }

• View::setSerializationContext and View::getSerializationContext have been removed. Use View::setContext and View::getContext together with the new Context class instead.

  Before:

  use JMS\Serializer\SerializationContext;
  
  $view = new View();
  
  $context = new SerializationContext();
  $view->setSerializationContext($context);
  
  $context = $view->getSerializationContext();

  After:

  use FOS\RestBundle\Context\Context;
  
  $view = new View();
  
  $context = new Context();
  $view->setContext($context);
  
  $context = $view->getContext();
