在scala中播放框架表单验证

Question

scala中的play框架表单验证工作遵循我的Signup对象,它在"mapping"(":"对象Forms中方法映射缺少参数的行中给出了一个错误;如果你想把它当作`_',请使用`_'这个方法部分应用的功能"

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.password1 == f.password2)
)

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)
)

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