Question

如何在（Scala）中构建反向路径播放2.4外部控制器？如果我导入controllers._并尝试使用路由，则会出现编译错误：

在此处找不到任何HTTP请求标头

package models 

import org.joda.time._ 
import play.api.libs.json._ 

case class Attendee (id: Long, status: Boolean, ... , pictureUrl: Option[String], ...) 

object Attendee { implicit val attendeeWrites = new Writes[Attendee] { 

def writes(att: Attendee) = Json.obj( "id" -> att.id, "picture" -> att.pictureUrl.map 
    { somePictureUrl => routes.PrivateWS.getAttendeeImage(att.eventId, att.id)
    .absoluteURL() })

我已经创建了一个帮助器并使用controllers.route.etc等并且运行良好，

在您的情况下，您可以尝试

<!-- Hover Code - Code that was added to change the ComboBox background 
     color when the use hovers over it with the mouse -->
<Trigger Property="IsMouseOver" Value="True">
   <Setter Property="Background" Value="DarkOrange"></Setter>
</Trigger>
<!-- Hover Code - End -->

在控制器外播放（2.4）路由
