在Scala中进行游戏框架表单验证的工作 跟随我的Signup对象，它在行"mapping(":"missing 对象形式中用于方法映射的参数；按照此方法使用"_"如果你想 将其视为部分应用的功能"

Working of play framework form validation in scala follows my Signup object, it gives me an error at the line "mapping(": "missing arguments for method mapping in object Forms; follow this method with `_' if you want to treat it as a partially applied function"

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) )

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) )

您丢失了("Passwords must match", f => f.password1 == f.password2)
