UPGRADE FROM 2.4 to 2.5
|
|
=======================
|
|
|
|
Routing
|
|
-------
|
|
|
|
* Added a new optional parameter `$requiredSchemes` to `Symfony\Component\Routing\Generator\UrlGenerator::doGenerate()`
|
|
|
|
Form
|
|
----
|
|
|
|
* The method `FormInterface::getErrors()` now returns an instance of
|
|
`Symfony\Component\Form\FormErrorIterator` instead of an array. This object
|
|
is traversable, countable and supports array access. However, you can not
|
|
pass it to any of PHP's `array_*` functions anymore. You should use
|
|
`iterator_to_array()` in those cases where you did.
|
|
|
|
Before:
|
|
|
|
```
|
|
$errors = array_map($callback, $form->getErrors());
|
|
```
|
|
|
|
After:
|
|
|
|
```
|
|
$errors = array_map($callback, iterator_to_array($form->getErrors()));
|
|
```
|
|
|
|
* The method `FormInterface::getErrors()` now has two additional, optional
|
|
parameters. Make sure to add these parameters to the method signatures of
|
|
your implementations of that interface.
|
|
|
|
Before:
|
|
|
|
```
|
|
public function getErrors()
|
|
{
|
|
```
|
|
|
|
After:
|
|
|
|
```
|
|
public function getErrors($deep = false, $flatten = true)
|
|
{
|
|
```
|
|
|
|
Before:
|
|
|
|
```
|
|
{% if form.vars.errors %}
|
|
```
|
|
|
|
After:
|
|
|
|
```
|
|
{% if form.vars.errors|length %}
|
|
```
|
|
|
|
PropertyAccess
|
|
--------------
|
|
|
|
* The methods `isReadable()` and `isWritable()` were added to
|
|
`PropertyAccessorInterface`. If you implemented this interface in your own
|
|
code, you should add these two methods.
|
|
|
|
* The methods `getValue()` and `setValue()` now throw an
|
|
`NoSuchIndexException` instead of a `NoSuchPropertyException` when an index
|
|
is accessed on an object that does not implement `ArrayAccess`. If you catch
|
|
this exception in your code, you should adapt the catch statement:
|
|
|
|
Before:
|
|
|
|
```php
|
|
$object = new \stdClass();
|
|
|
|
try {
|
|
$propertyAccessor->getValue($object, '[index]');
|
|
$propertyAccessor->setValue($object, '[index]', 'New value');
|
|
} catch (NoSuchPropertyException $e) {
|
|
// ...
|
|
}
|
|
```
|
|
|
|
After:
|
|
|
|
```php
|
|
$object = new \stdClass();
|
|
|
|
try {
|
|
$propertyAccessor->getValue($object, '[index]');
|
|
$propertyAccessor->setValue($object, '[index]', 'New value');
|
|
} catch (NoSuchIndexException $e) {
|
|
// ...
|
|
}
|
|
```
|
|
|
|
A `NoSuchPropertyException` is still thrown when a non-existing property is
|
|
accessed on an object or an array.
|
|
|
|
Validator
|
|
---------
|
|
|
|
* EmailValidator has changed to allow `non-strict` and `strict` email validation
|
|
|
|
Before:
|
|
|
|
Email validation was done with php's `filter_var()`
|
|
|
|
After:
|
|
|
|
Default email validation is now done via a simple regex which may cause invalid emails (not RFC compliant) to be
|
|
valid. This is the default behaviour.
|
|
|
|
Strict email validation has to be explicitly activated in the configuration file by adding
|
|
|
|
```
|
|
framework:
|
|
//...
|
|
validation:
|
|
strict_email: true
|
|
//...
|
|
|
|
```
|
|
|
|
Also you have to add to your composer.json:
|
|
|
|
```
|
|
"egulias/email-validator": "~1.2"
|
|
```
|
|
|
|
* `ClassMetadata::getGroupSequence()` now returns `GroupSequence` instances
|
|
instead of an array. The sequence implements `\Traversable`, `\ArrayAccess`
|
|
and `\Countable`, so in most cases you should be fine. If you however use the
|
|
sequence with PHP's `array_*()` functions, you should cast it to an array
|
|
first using `iterator_to_array()`:
|
|
|
|
Before:
|
|
|
|
```
|
|
$sequence = $metadata->getGroupSequence();
|
|
$result = array_map($callback, $sequence);
|
|
```
|
|
|
|
After:
|
|
|
|
```
|
|
$sequence = iterator_to_array($metadata->getGroupSequence());
|
|
$result = array_map($callback, $sequence);
|
|
```
|
|
|
|
* The array type hint in `ClassMetadata::setGroupSequence()` was removed. If
|
|
you overwrite this method, make sure to remove the type hint as well. The
|
|
method should now accept `GroupSequence` instances just as well as arrays.
|
|
|
|
Before:
|
|
|
|
```
|
|
public function setGroupSequence(array $groups)
|
|
{
|
|
// ...
|
|
}
|
|
```
|
|
|
|
After:
|
|
|
|
```
|
|
public function setGroupSequence($groupSequence)
|
|
{
|
|
// ...
|
|
}
|
|
```
|
|
|
|
* The validation engine in `Symfony\Component\Validator\Validator` was replaced
|
|
by a new one in `Symfony\Component\Validator\Validator\RecursiveValidator`.
|
|
With that change, several classes were deprecated that will be removed in
|
|
Symfony 3.0. Also, the API of the validator was slightly changed. More
|
|
details about that can be found in UPGRADE-3.0.
|
|
|
|
You can choose the desired API via the new "api" entry in
|
|
app/config/config.yml:
|
|
|
|
```
|
|
framework:
|
|
validation:
|
|
enabled: true
|
|
api: auto
|
|
```
|
|
|
|
When running PHP 5.3.9 or higher, Symfony will then use an implementation
|
|
that supports both the old API and the new one:
|
|
|
|
```
|
|
framework:
|
|
validation:
|
|
enabled: true
|
|
api: 2.5-bc
|
|
```
|
|
|
|
When running PHP lower than 5.3.9, that compatibility layer is not supported.
|
|
On those versions, the old implementation will be used instead:
|
|
|
|
```
|
|
framework:
|
|
validation:
|
|
enabled: true
|
|
api: 2.4
|
|
```
|
|
|
|
If you develop a new application that doesn't rely on the old API, you can
|
|
also set the API to 2.5. In that case, the backwards compatibility layer
|
|
will not be activated:
|
|
|
|
```
|
|
framework:
|
|
validation:
|
|
enabled: true
|
|
api: 2.5
|
|
```
|
|
|
|
When using the validator outside of the Symfony full-stack framework, the
|
|
desired API can be selected using `setApiVersion()` on the validator builder:
|
|
|
|
```
|
|
// Previous implementation
|
|
$validator = Validation::createValidatorBuilder()
|
|
->setApiVersion(Validation::API_VERSION_2_4)
|
|
->getValidator();
|
|
|
|
// New implementation with backwards compatibility support
|
|
$validator = Validation::createValidatorBuilder()
|
|
->setApiVersion(Validation::API_VERSION_2_5_BC)
|
|
->getValidator();
|
|
|
|
// New implementation without backwards compatibility support
|
|
$validator = Validation::createValidatorBuilder()
|
|
->setApiVersion(Validation::API_VERSION_2_5)
|
|
->getValidator();
|
|
```
|
|
|
|
|
|
Yaml Component
|
|
--------------
|
|
|
|
* The way Yaml handles duplicate keys in an array was changed from `rewrite with the
|
|
last element` behavior to ignoring all the elements with the same key after the first one.
|
|
|
|
Example:
|
|
|
|
```
|
|
parentElement:
|
|
firstChild: foo
|
|
secondChild: 123
|
|
firstChild: bar
|
|
```
|
|
|
|
Before:
|
|
|
|
This would be parsed in an array like this: `["parentElement" => ["firstChild" => "bar", "secondChild" => 123]]`
|
|
|
|
After:
|
|
|
|
The first value is used: `["parentElement" => ["firstChild" => "foo", "secondChild" => 123]]`
|
