New in Symfony 4.2: DivisibleBy constraint

in #28069.
In Symfony 4.2, the Validator component has introduced a new DivisibleBy
constraint to check whether one number is a multiple of ("divisible by") some
other number. It's mostly useful for enforcing specific increments on a number:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | // src/Entity/Item.php
namespace App\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class Item
{
/**
* @Assert\DivisibleBy(0.25)
*/
protected $weight;
/**
* @Assert\DivisibleBy(
* value = 5,
* message = "This item requires to be stocked in multiples of 5 units."
* )
*/
protected $quantity;
}
|
These constraints ensure that the weight
of the Item
is provided in
increments of 0.25
(e.g. 0.75
and 4.50
would be correct, but
0.18
or 7.32
wouldn't) and the quantity
must be divisible by 5
(25
and 22620
would be correct but 12
or 123456
wouldn't).
Comments
@javier I would suggest not using the thousands separator in the example as it seems to confuse people ;)
