当我请求时(通过 Insomnia、类似 postman 的 API 工具、已设置 header )

{
  "username": "cerseilann",
  "password": "password",
  "email": "cerseilann@example.com",
  "name": "Cersei Lannister Duplicate",
  "retypePassword": "password"
}

我期待一些与唯一值相关的错误消息。但相反，我收到此错误:

该值的类型应为 array|IteratorAggregate

完整回复

{
  "@context": "\/api\/contexts\/ConstraintViolationList",
  "@type": "ConstraintViolationList",
  "hydra:title": "An error occurred",
  "hydra:description": "username: This value should be of type array|IteratorAggregate.\nemail: This value should be of type array|IteratorAggregate.",
  "violations": [

    },
    {
      "propertyPath": "email",
      "message": "This value should be of type array|IteratorAggregate."
    }
  ]
}

我错过了什么？

编辑

当我使用 UniqueEntity 并删除 Unique

...
 * @ORM\Entity(repositoryClass="App\Repository\UserRepository")
 * @UniqueEntity(fields="username", message="Username {{ value }} already taken. Please use another username.")
 * @UniqueEntity(fields="email", message="Email {{ value }} already being used. COnsider forgot password to retrieve the password.")
 */

...

我收到此返回错误

  "@type": "hydra:Error",
  "hydra:title": "An error occurred",
  "hydra:description": "An exception occurred while executing 'INSERT INTO user (username, email, roles, password, password_change_date, name, is_active, confirmation_token) VALUES (?, ?, ?, ?, ?, ?, ?, ?)' with params [\"cerseilann\", \"cerseilann1@example.com\", \"[\\\u0022ROLE_USER\\\u0022]\", \"$argon2id$v=19$m=65536,t=4,p=1$0Wu+2mjS\\\/Uft6lu2ieJOMQ$6ostmakEH2LKYKVvr5PYCoFOZvDwwNT\\\/\\\/+xI+g9hkG8\", null, \"Cersei Lannister 1\", 0, \"adde39972ac50feb3918\"]:\n\nSQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'cerseilann' for key 'UNIQ_8D93D649F85E0677'",

我期待出现错误消息。

Answer 1

Unique约束用于集合(意思是:保存集合的字段)，并确定所有条目是否唯一。

您可能想要什么:

UniqueEntity约束 - 它必须在实体上设置，而不是字段，但您可以为每个字段设置两次和一次，并将其 fields 属性分别设置为适当的字段。
