播放表单验证

Question

如何在播放表单中添加验证？

下面是重置密码表单，需要用户输入两次密码。

@(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。

谢谢比利

你可以这样做：

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，查看 docs for that purpose
