how to display data table items in the reverse order in order of id ...

back language i'am using scala 

reverse order  data in the data table or models,and display on  in view the page using,
play framework or Normal html

在查看页面...

@helper.form(action = routes.Application.listAllpost) {
<fieldset>
@for(post<- posts){
<h3>
@post.name </h3><br/><br/>
</fieldset>
}

并在列出帖子的应用程序页面中

val pos:Post=null
val postNotifiaction:PostNotification=null
def listAllpost()= Action{

    val post:List[Post]=Post.listAllPostById
    Ok(views.html.allPosts.render(Application.postNotificationForm,post,pos,postNotifiaction))
      }

def listPsts = Action { implicit request =>
        val today = Calendar.getInstance().getTime()
        val alert: Alert = new Alert("", "")
        Common.setAlert(alert)
        createPostForm.bindFromRequest.fold(
        errors => BadRequest(views.html.createPost(errors, "There is some error","")),
    post => {
        Post.findByPostName(post.name).isEmpty match {
    case true =>  case false =>
        }
        Results.Redirect("/post")
       })
    }

在这里,我在重新加载最后一个页面时在 db 中添加一个post..

所以我希望最后一篇文章在顶部..有任何方法..任何人都知道方法..请在此处提及....

List.reverseIterator()返回“以相反顺序产生元素的迭代器”,您可以使用相反的顺序列出您的帖子

@for(post <- posts.reverseIterator()) {
    @post.name<br>
}
