播放表单验证 [英] Play form verification

问题描述

如何在播放表单中添加验证?

How to add validation in play form?

下面是重置密码表单，希望用户输入两次密码.

Below is reset password form which expects user to enter password twice.

@(tokenId: String, form: Form[ResetPassword])(implicit messages: play.api.i18n.Messages, request: RequestHeader)
@main("Reset Password") {
  @helper.form(routes.Application.handleResetPassword(tokenId)) {

    @helper.inputText(form("password1"))

    @helper.inputText(form("password2"))

    <button type="submit">Submit</button>

  }

}

在上面的表格中，我想添加验证，以检查password1和password2是否相同.

In above form, I would like to add validation that will check if password1 and password2 are same or not.

谢谢 帕里

推荐答案

您可以这样做:

val userFormConstraintsAdHoc = Form(
  mapping(
    "password1" -> text,
    "password2" -> text
  )(UserData.apply)(UserData.unapply) verifying("Failed form constraints!", fields => fields match {
    case userData => form.password1.equals(form.password2)
  })
)

这只是未经测试的伪代码，请查看文档以了解这个目的
