I need to change format for DateTime validation constraint but I want to do it globally for the whole application to not copy-paste it like this:
dateFrom:
- DateTime
format: Y-m-d\TH:i:s.vP
dateTo:
- DateTime
format: Y-m-d\TH:i:s.vP
(I use yaml config in my application)
Is there any option to do it globally in Symfony 5 application, using DI parameters or some other way?
I didn't find anything about it in official documentation.
You can create a custom constraint extending Symfony\Component\Validator\Constraints\DateTime and set the format there.
// src/Validator/Constraints/MyDateTime.php
namespace App\Validator\Constraints;
use Symfony\Component\Validator\Constraints\DateTime as BaseDateTime;
class MyDateTime extends BaseDateTime
{
public $format = 'Y-m-d\TH:i:s.vP';
public function validatedBy()
{
// use the same validator without this symfony will look for 'App\Validator\Constraints\MyDateTimeValidator'
//return static::class.'Validator';
return parent::class.'Validator';
}
}
Then you just use custom constraint where needed.
# config/validator/validation.yaml
App\Entity\Author:
properties:
createdAt:
- NotBlank: ~
- App\Validator\Constraints\MyDateTime: ~
// src/Entity/Author.php
namespace App\Entity;
use Symfony\Component\Validator\Constraints as Assert;
use App\Validator\Constraints as MyAssert;
class Author
{
/**
* @Assert\NotBlank
* @MyAssert\MyDateTime
* @var string A "Y-m-d\TH:i:s.vP" formatted value
*/
protected $createdAt;
}
So your config would look like this:
dateFrom:
- App\Validator\Constraints\MyDateTime: ~
