UPGRADE FROM 2.6 to 2.7

Router

• Route conditions now support container parameters which can be injected into condition using %parameter% notation. Due to the fact that it works by replacing all parameters with their corresponding values before passing condition expression for compilation there can be BC breaks where you could already have used percentage symbols. Single percentage symbol usage is not affected in any way. Conflicts may occur where you might have used % as a modulo operator, here's an example: foo%bar%2 which would be compiled to $foo % $bar % 2 in 2.6 but in 2.7 you would get an error if bar parameter doesn't exist or unexpected result otherwise.

Form

• In form types and extension overriding the "setDefaultOptions" of the AbstractType or AbstractExtensionType has been deprecated in favor of overriding the new "configureOptions" method.

  The method "setDefaultOptions(OptionsResolverInterface $resolver)" will be renamed in Symfony 3.0 to "configureOptions(OptionsResolver $resolver)".

  Before:

       use Symfony\Component\OptionsResolver\OptionsResolverInterface;
  
       class TaskType extends AbstractType
       {
           // ...
           public function setDefaultOptions(OptionsResolverInterface $resolver)
           {
               $resolver->setDefaults(array(
                   'data_class' => 'AppBundle\Entity\Task',
               ));
           }
       }
  

  After:

       use Symfony\Component\OptionsResolver\OptionsResolver;
  
       class TaskType extends AbstractType
       {
           // ...
           public function configureOptions(OptionsResolver $resolver)
           {
               $resolver->setDefaults(array(
                   'data_class' => 'AppBundle\Entity\Task',
               ));
           }
       }
  

Serializer

• The setCamelizedAttributes() method of the Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer and Symfony\Component\Serializer\Normalizer\PropertyNormalizer classes is marked as deprecated in favor of the new NameConverter system.

  Before:

  $normalizer->setCamelizedAttributes(array('foo_bar', 'bar_foo'));
  

  After:

  use Symfony\Component\Serializer\NameConverter\CamelCaseToSnakeCaseNameConverter;
  use Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer;
  
  $nameConverter = new CamelCaseToSnakeCaseNameConverter(array('fooBar', 'barFoo'));
  $normalizer = new GetSetMethodNormalizer(null, $nameConverter);
  

PropertyAccess

• UnexpectedTypeException now expects three constructor arguments: The invalid property value, the PropertyPathInterface object and the current index of the property path.

  Before:

       use Symfony\Component\PropertyAccess\Exception\UnexpectedTypeException;
  
       new UnexpectedTypeException($value, $expectedType);
  

  After:

       use Symfony\Component\PropertyAccess\Exception\UnexpectedTypeException;
  
       new UnexpectedTypeException($value, $path, $pathIndex);
