Answer 1

case class UserRegistration(username: String, password1: String, password2: String)

val loginForm = Form(
  mapping(
    "username" -> email,
    "password1" -> text,
    "password2" -> text
  )
  (UserRegistration.apply)(UserRegistration.unapply)
  verifying ("Passwords must match", f => f.password1 == f.password2)
)

您错过了("Passwords must match", f => f.password1 == f.password2)
