symfony: Format date in assert message - symfony

Question

I have assertion on my entity to validate dates. It's work well, but the outuput is formated whith time. I need only the date. (The text is in french)
My entity :
/**
* #var \DateTime
* #Assert\DateTime(format="d/m/Y")
* #Assert\LessThanOrEqual(
* value="-2 days",
* message="rapports.max_date"
* )
*/
protected $dateDebut;
My translation file :
max_date: 'La date saisie doit être inférieur ou égale au {{ compared_value }}.'
That output is "La date saisie doit être supérieur ou égale au 1 janv. 2015 à 01:00.". I want "La date saisie doit être supérieur ou égale au 01/001/2015."
I want to format the 'compared_value'. WHo can I do that ?

Answer 1

Maybe use the date_format filter:
max_date: 'La date saisie doit être inférieur ou égale au {{ compared_value | date_format('Y-m-d') }}.'

Answer 2

You can do the following:
Write a service and make it globally available to the twig engine.
This service has to define a public function that takes the compared_value, parses the wrongly formatted date, and outputs the correctly formatted one.
So:
class MyService
{
public function parse($compared_value) {
return date_format('Y-m-d', strtotime($compared_value));
}
}
in config.yml
twig:
globals:
my_service: '#my_service'
services:
my_service:
class: AppBundle\Service\MyService
and finally
max_date: 'La date saisie doit être inférieur ou égale au {{ my_service.parse(compared_value) }}.'
