New in Symfony 4.1: Misc. improvements (part 3)

May 28, 2018 Javier Eguiluz

Allow to set the rounding strategy for `MoneyType`¶

In Symfony 4.1, the MoneyType form field defines a new option called rounding_mode to control how the values are rounded. Before, all values were rounded towards "the nearest neighbor" (ROUND_HALF_UP) so 15.999 was rounded as 16.00. Now you can set it for example to ROUND_DOWN to display it as 15.99:

use Symfony\Component\Form\Extension\Core\DataTransformer\NumberToLocalizedStringTransformer;
use Symfony\Component\Form\Extension\Core\Type\MoneyType;
// ...

$builder->add('price', MoneyType::class, array(
    'rounding_mode' => NumberToLocalizedStringTransformer::ROUND_DOWN,
));

Adding and removing LDAP attributes more efficiently¶

Contributed by
Jean-Guilhem Rouel
in #21856.

Updating LDAP entries with the update() is slow in some scenarios. That's why in Symfony 4.1 there are two new methods called addAttributeValues() and removeAttributeValues() that add/remove values to a multi-valued attribute:

use Symfony\Component\Ldap\Ldap;
 use Symfony\Component\Ldap\Entry;
 // ...

$entry = $ldap->query('...', '...')->execute()[0];

$entityManager = $ldap->getEntryManager();
$entityManager->addAttributeValues($entry, 'telephoneNumber', ['+1.111.222.3333', '+1.222.333.4444']);
$entityManager->removeAttributeValues($entry, 'telephoneNumber', ['+1.111.222.3333', '+1.222.333.4444']);

Keep query string after redirecting¶

Contributed by
Hamza Amrouche
in #26281.

In Symfony 4.1, routes can define (in YAML, XML or PHP) a new option called keepQueryParams. By default it's false, but if you set it to true, the query parameters (if any) are added to the redirected URL:

legacy_search:
    path: /search-engine
    controller: Symfony\Bundle\FrameworkBundle\Controller\RedirectController::redirectAction
    defaults:
        route: search
        permanent: true
        keepQueryParams: true

In this example, if the original URL is /search-engine?q=symfony, the app redirects to /search?q=symfony

Added support for hasser accessors in PropertyInfo¶

Contributed by
Sébastien Decrême
in #23617.

The PropertyInfo component introspects information about class properties by using different sources of metadata. In Symfony 4.1, one of those sources (the ReflectionExtractor class) added support for hasser methods.

This will allow for example to make a property readable by defining methods like hasChildren() instead of just getChildren().

"so 15.999 was rounded as 15.10" i would hope not

@Bart that would be a really bad rounding! It's fixed now. Thanks.

@Javier

"that would be a really bad rounding" --- any money rounding is bad rounding.

I do like the redirection with queryParams !

Good job

@Ivan sure! And in the Symfony Docs (e.g. https://symfony.com/doc/current/doctrine.html) we mention this:

> Confused why the price is an integer? Don't worry: this is just an example.
> But, storing prices as integers (e.g. 100 = $1 USD) can avoid rounding issues.
