symfony断言忽略自定义消息

Question

I have this code in Entity:

/**
     * @Assert\Type(
     *     type="real",
     *     message="Price for vehicle service must be real number."
     * )
     *
     * @ORM\Column(name="min_price", type="float")
     */
    protected $minPrice;

But if in this form field is entered noninteger value, Symfony returns default locale error message (in my case Значение недопустимо), and not the "Price for vehicle service must be real number.". This is not comfortable, because in error not specified field name, and needed time to find this field if there are complex form.

Maybe as solution can be callback validation, but in my subjective opinion it would not appear, because user can see only locale default message. When I tried to avoid it adding @Assert\Regex(pattern="/+d/", message="custom message"), I anyway saw the locale default message.

Symfony Profiler shows error below:

Symfony\Component\Validator\ConstraintViolation
Object(Symfony\Component\Form\Form).children[vehiclePriceOutOfTown].children[minPrice] = g
Caused by:
Symfony\Component\Form\Exception\TransformationFailedException
Unable to reverse value for property path "minPrice": Number parsing failed: U_PARSE_ERROR
Caused by:
Symfony\Component\Form\Exception\TransformationFailedException

The exception you see is triggered during the transformation of the user's input. This happens before the actual validation logic is applied (this happens as part of the POST_SUBMIT event). If you want to customise the error message being shown when a TransformationFailedException is thrown, you can use the invalid_message option for the particular form type.
