Symfony 2.5 addViolation在不建议使用的情况下，请使用buildViolation() [英] Symfony 2.5 addViolationAt deprecated, use buildViolation()

问题描述

我一直在关注烹饪书关于如何创建类约束验证器的信息，现在我正要在validate()函数中添加违规的地方.

I have been following the cookbook on how to create a class constraint validator and right now I am at the point where I am about to add the violation in the validate() function.

但是我的IDE通知我功能addViolation()和addViolationAt()已弃用.

However my IDE notifies me the functions addViolation() and addViolationAt() are deprecated.

有人可以向我指出如何使用 Context\ExecutionContextInterface::buildViolation() 函数?

Can someone point me in the right direction on how to use the Context\ExecutionContextInterface::buildViolation() function instead?

$this->context是 Symfony\Component\Validator\ExecutionContext 的实例

class ProtocolClassValidator extends ConstraintValidator
{
    public function validate($protocol, Constraint $constraint)
    {
        if ($protocol->getFoo() != $protocol->getBar()) {
            $this->context->addViolationAt(
                'foo',
                $constraint->message,
                array(),
                null
            );
        }
    }
}

将呼叫$this->context->addViolationAt()更改为简单的$this->context->buildViolation()时，出现以下异常:

When changing the call $this->context->addViolationAt() to simply $this->context->buildViolation(), I get the following Exception:

UndefinedMethodException:尝试在以下位置调用方法"buildViolation" 类别中的"Symfony \ Component \ Validator \ ExecutionContext" 剥离路径 第23行.您是说要打电话给"addViolation"吗?

UndefinedMethodException: Attempted to call method "buildViolation" on class "Symfony\Component\Validator\ExecutionContext" in stripped path line 23. Did you mean to call: "addViolation"?

第23行包含以下代码:

and line 23 has the following code:

    $builder = $this->context->buildViolation($constraint->message)
    ->atPath('formField')
    ->addViolation();

推荐答案

addViolation和addViolationAt从2.5弃用，但直到3.0才被删除，因此它们仍然可以使用很长时间.

addViolation and addViolationAt are deprecated from 2.5 but won't be removed until 3.0 so they are still usable for a good time.

但是...取自从2.x升级到3.0 记录...

However... taken from the the UPGRADE FROM 2.x to 3.0 log...

The method `addViolationAt()` was removed. You should use `buildViolation()`
instead.

Before:

$context->addViolationAt('property', 'The value {{ value }} is invalid.', array(
    '{{ value }}' => $invalidValue,
));

After:

$context->buildViolation('The value {{ value }} is invalid.')
    ->atPath('property')
    ->setParameter('{{ value }}', $invalidValue)
    ->addViolation();
));

With a bit more taken from Context/ExecutionContextInterface...

/**
 * Returns a builder for adding a violation with extended information.
 *
 * Call {@link ConstraintViolationBuilderInterface::addViolation()} to
 * add the violation when you're done with the configuration:
 *
 *     $context->buildViolation('Please enter a number between %min% and %max.')
 *         ->setParameter('%min%', 3)
 *         ->setParameter('%max%', 10)
 *         ->setTranslationDomain('number_validation')
 *         ->addViolation();
 *
 * @param string $message    The error message
 * @param array  $parameters The parameters substituted in the error message
 *
 * @return ConstraintViolationBuilderInterface The violation builder

public function buildViolation($message, array $parameters = array());
