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:
|
|
|
|
```php
|
|
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
|
|
|
|
class TaskType extends AbstractType
|
|
{
|
|
// ...
|
|
public function setDefaultOptions(OptionsResolverInterface $resolver)
|
|
{
|
|
$resolver->setDefaults(array(
|
|
'data_class' => 'AppBundle\Entity\Task',
|
|
));
|
|
}
|
|
}
|
|
```
|
|
|
|
After:
|
|
|
|
```php
|
|
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:
|
|
|
|
```php
|
|
$normalizer->setCamelizedAttributes(array('foo_bar', 'bar_foo'));
|
|
```
|
|
|
|
After:
|
|
|
|
```php
|
|
use Symfony\Component\Serializer\NameConverter\CamelCaseToSnakeCaseNameConverter;
|
|
use Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer;
|
|
|
|
$nameConverter = new CamelCaseToSnakeCaseNameConverter(array('fooBar', 'barFoo'));
|
|
$normalizer = new GetSetMethodNormalizer(null, $nameConverter);
|
|
```
