UPGRADE FROM 2.7 to 2.8
=======================
Form
----
* The "cascade_validation" option was deprecated. Use the "constraints"
option together with the `Valid` constraint instead. Contrary to
"cascade_validation", "constraints" must be set on the respective child forms,
not the parent form.
Before:
```php
$form = $this->createForm('form', $article, array('cascade_validation' => true))
->add('author', new AuthorType())
->getForm();
```
After:
use Symfony\Component\Validator\Constraints\Valid;
$form = $this->createForm('form', $article)
->add('author', new AuthorType(), array(
'constraints' => new Valid(),
))
Alternatively, you can set the `Valid` constraint in the model itself:
use Symfony\Component\Validator\Constraints as Assert;
class Article
{
/**
* @Assert\Valid
*/
private $author;
}
Translator
----------
* The `getMessages()` method of the `Symfony\Component\Translation\Translator` was deprecated and will be removed in
Symfony 3.0. You should use the `getCatalogue()` method of the `Symfony\Component\Translation\TranslatorBagInterface`.
$messages = $translator->getMessages();
$catalogue = $translator->getCatalogue($locale);
$messages = $catalogue->all();
while ($catalogue = $catalogue->getFallbackCatalogue()) {
$messages = array_replace_recursive($catalogue->all(), $messages);
