根据另一个字段来验证一个字段的约束注解

Question

我在Symfony/5.4中有这个实体类:

use DoctrineORMMapping as ORM;
use SymfonyComponentValidatorConstraints as Assert;

class Assignments
{
    public const SALARY_RANGES = [
        'Red',
        'Green',
        null,
    ];

    /*** @ORMColumn(长度=255,可为空=true)
     * @AssertChoice(choices=Assignments::SALARY_RANGES, strict=true)*/
    private ?string $salaryRange;

    /*** @ORMManyToOne（targetEntity =“员工”，inversedBy =“分配”）
     * @ORMJoinColumn（name =“employee_id”，referencedColumnName =“id”，onDelete =“CASCADE”）*/
    private ?Employee $employee;
}

我需要确保如果employee不为空，则salaryRange具有非空值，反之亦然。是否可以使用约束注解来强制实施这一要求?

我一直在尝试使用@AssertCallback，但我无法弄清楚如何获取其他字段的值。也许这甚至不是正确的工具。

/*** @AssertCallback({"ExampleValidator", "assertEmployeeOnlyCallback"})*/

public static function assertEmployeeOnlyCallback(mixed $data, ExecutionContextInterface $context): void
{
    // `$data` contains value from `salaryRange` but, where is `employee`?
}

只需按照文档进行操作。

https://symfony.com/doc/5.3/reference/constraints/Callback.html

class Author
{
    // ...
    private int $field = 1;
    private string $otherField;
   /**
    * @Assert\Callback
    */    
    public function validate(ExecutionContextInterface $context, mixed $payload): void
    {
        
        if ($this->field > 1 && $this->otherField != '') {
            $context->buildViolation('Your validation message')
                ->atPath('toherField')
                ->addViolation();
        }
    }
}
