使用密码确认在注册表单上键入不匹配

Question

我想用密码确认进行注册表格并复制此样本https://github.com/namin/play-js-validation

但类型不匹配发生

规模2.11发挥2.5

object SignUpForm {

  val form = Form(
    mapping(
      "firstName" -> nonEmptyText,
      "lastName" -> nonEmptyText,
      "email" -> nonEmptyText,
      // "password" -> nonEmptyText
      "password" ->
            tuple(
                "main" -> nonEmptyText,
                "confirm" -> nonEmptyText
            ).verifying("Passwords don't match",passwords  => passwords._1 == passwords._2)
    )(Data1.apply)(Data1.unapply)
  )

    // The mapping signature doesn't match the User case class signature,
    // so we have to define custom binding/unbinding functions
    {
      // Binding: Create a User from the mapping result (ignore the second password and the accept field)
      (firstName, lastName, email, passwords, _) => Data2(firstName, lastName, email, passwords._1)
    } 

  case class Data1(
    firstName: String,
    lastName: String,
    email: String,
    password1: String,
    password2: String
)

  case class Data2(
    firstName: String,
    lastName: String,
    email: String,
    password: String
)

}

类型不匹配; found：（String，String，String，String，String）=> forms.SignUpForm.Data1 required：（String，String，String，（String，String））=>？

也许case类Data1应该被修改但是brace（）不能嵌套。例如，

  case class Data1(
    firstName: String,
    lastName: String,
    email: String,
    (password1: String,
    password2: String)
  )

发生了错误

5/24（2小时后）重写但发生意外异常。不知道在哪里插入.verifying（）

[模型]

  case class Data(
    firstName: String,
    lastName: String,
    email: String,
    password: forms.SignUpForm.PassData
  )

  case class PassData(
    main: String,
    confirm: String
  )

[signupform]

  val form = Form[Data](
    mapping(
      "firstName" -> nonEmptyText,
      "lastName" -> nonEmptyText,
      "email" -> nonEmptyText,
      // "password" -> nonEmptyText
      "password" -> mapping(
        "main" -> nonEmptyText,
        "confirm" -> nonEmptyText
      )(PassData.apply)(PassData.unapply)
 // following .verifying is not appropriate
 .verifying("Passwords don't match",password  => password.main == password.confirm)
//(PassData.apply)(PassData.unapply)
    )(Data.apply)(Data.unapply)
   ) 

CreationException：无法创建注入器，请参阅以下错误：

1) Error injecting constructor, org.quartz.SchedulerException: Scheduler with name 'QuartzScheduler~application' already exists.

5/24（4小时后）发现了这个问题并解决了。 play framework form validation in scala

  val form = Form[Data](
    mapping(
      "firstName" -> nonEmptyText,
      "lastName" -> nonEmptyText,
      "email" -> nonEmptyText,
      "main" -> nonEmptyText,
      "confirm" -> nonEmptyText 
    )(Data.apply)(Data.unapply)
 verifying("Passwords don't match", password  => password.main == password.confirm)

  case class Data(
    firstName: String,
    lastName: String,
    email: String,
    main: String,
    confirm: String
  )

尝试使用嵌套表单https://www.playframework.com/documentation/2.6.x/ScalaForms#nested-values

您可以为密码创建一个字段，并在密码字段中嵌套两个字段。
