forms - Scala example of inputRadioGroup in Play2.1 -

i'm browsing around in documentation can't find example of how use inputradiogroup in controller.

i guess should use this helper. how bind form in controller? show radio group represents grades 1 - 5

controller:

object sms extends controller {    val testform: form[test] = form (     mapping(       "firstname" -> nonemptytext,       "lastname" -> nonemptytext,       "password" -> tuple(         "main" -> text(minlength = 6),         "confirm" -> text       ).verifying(         "passwords don't match", passwords => passwords._1 == passwords._2       ),       "email" -> tuple(         "main" -> (text verifying pattern("^([0-9a-za-z]([-\\.\\w]*[0-9a-za-z])*@([0-9a-za-z][-\\w]*[0-9a-za-z]\\.)+[a-za-z]{2,9})$".r, error="a valid email req")),         "confirm" -> text         ).verifying(         "emails don't match", emails => emails._1 == emails._2       ),       "grade" -> magic happen here?     )(test.apply)(test.unapply)   )    case class test(                     firstname: string,                     lastname: string,                     password: string,                     email: string,                     grade: int                     )  } 

view:

@inputradiogroup( testform("grade"), options = seq("1"->1,"2"->2....and on) '_label -> "grade", '_error -> testform("grade").error.map(_.withmessage("some error"))) 

i can't figure out how this.

in controller create seq of possible grades , pass seq view. using case class grade better pass tuple2[string, string] view. guess that's matter of opinion.

case class grade(value: int, name: string) private val grades = seq(grade(1, "brilliant"), grade(2, "good"), grade(3, "ok"))   val testform: form[test] = form (... "grade"-> number )(test.apply)(test.unapply)  def edit(id: long) = action {   val model = ...obtain model   ok(views.html.edit(testform.fill(model), grades)) }  def submit() = action {    testform.bindfromrequest.fold(    formwitherrors => ok(views.html.edit(formwitherrors, grades))   }, test => {     logger.info("grade: " +  grades.find(_.value == test.grade).map(_.name))     //save model...     redirect(...   }) } 

in view, map grades seq tuple2[string, string] feed inputradiogroup

@(testform: form[test], grades: seq[grade])  @inputradiogroup(contactform("grade"),  options = grades.map(g => g.value.tostring -> g.name),  '_label -> "grade")
