Php Symfony检查输入数据是否唯一

我有一个自定义验证数组，没有如下实体：

$dataContent = json_decode($request->getContent(), true);

$dataToCheck = [
            'name' => [
                new Assert\Required(),
                new Assert\NotBlank(),
                new Assert\Type('string'),
                new Assert\Length(['min' => 4]),
            ],
            'nick' => [
                new Assert\Required(),
                new Assert\NotBlank(),
                new Assert\Type('string'),
                new Assert\Length(['min' => 4]),
            ],
            'email' => [
                new Assert\Required(),
                new Assert\NotBlank(),
                new Assert\Email(),
            ]
]

$constraint = new Assert\Collection($dataToCheck);
$violations = $validator->validate($dataContent, $constraint);

在MongoDb中，我有一些用户。我需要检查请求中的“尼克”和“电子邮件”是否唯一。 所以，在添加新用户的过程中，如何向字段添加规则，以检查这些字段在数据库中是否唯一。 在用户更新当前用户Id的详细信息时，如何忽略检查唯一字段

谢谢。

根据文档，其中一个解决方案是如下操作：

您可以创建用户实体 然后定义UserType 您使用验证组是因为，根据您所说的，您不想验证用于更新的唯一字段，而只是为了创建

最后，在控制器中，您可以执行以下操作： 更新：要在没有实体的情况下执行此操作， 根据本文档，您可以使用自定义约束名称（如UniqueCustom）并将其添加到约束数组中。在此自定义约束中，您可以检查MongoDB中是否已经存在相应的电子邮件或nick。若要忽略此更新检查，可以使用如上所述的验证组。因此，您的约束数组似乎只是一个想法：

$dataToCheck = [
            'email' => [
                new Assert\Required(['groups' => ['new', 'edit']]),
                new Assert\NotBlank(['groups' => ['new', 'edit']]),
                new Assert\Type('string'),
                new Assert\Email(['groups' => ['new', 'edit']]),
                new UniqCustom(['groups' => ['new']]) // Custom uniq constraint
            ],
            'nick' => [
                new Assert\Required(['groups' => ['new', 'edit']]),
                new Assert\NotBlank(['groups' => ['new', 'edit']]),
                new Assert\Type('string'),
                new Assert\Length(['min' => 4, 'groups' => ['new', 'edit']]),
                new UniqCustom(['groups' => ['new']])
            ],
            'name' => [
                new Assert\Required(['groups' => ['new', 'edit']]),
                new Assert\NotBlank(['groups' => ['new', 'edit']]),
                new Assert\Type('string'),
                new Assert\Length(['min' => 4, 'groups' => ['new', 'edit']]),
            ],

        ];

ODM的过程与用户ORM类似。

我希望这个解决方案的尝试能对您有所帮助。

请查看更多信息。我已经看过了，但我不知道如何实现我的示例。如果您能为我的示例编写小的实现，我将不胜感激。谢谢，谢谢。但我知道如何在你们介绍的例子中做到这一点。在我的例子中，我不能使用实体。我需要在没有实体的情况下做这件事。就像我上面的例子一样。有可能吗？
