}

在错误请求期间应使用什么语法再次访问该表单并获得该emplist，无论何时在错误请求中，form.get（）都没有用，似乎表单本身在请求期间不一样索引

控制器 索引

@Transactional
public static Result index() {
System.out.print("asdf");
appModel = new ApplicationModel();
Form<ApplicationModel> form = 
Form.form(ApplicationModel.class).fill(appModel.init(appModel));
return ok(index.render(form));
}

控制器 提交后，我希望再次显示所有内容，但当我错误提交时，我现在只能显示错误而不能保留其值

@Transactional
public static Result addEdit() {
Form<ApplicationModel> form = 
Form.form(ApplicationModel.class).bindFromRequest();
if (form.hasErrors()) {
  return badRequest(index.render(form));
}
form.get().update();
ApplicationModel newAppModel = new ApplicationModel();
form = Form.form(ApplicationModel.class).fill(newAppModel.init(newAppModel));
return ok(index.render(form));
}

解决方案：经过多次尝试和错误

将其括起来并访问您想要获得的特定值

@for(i <- 0 to {form("emplist").indexes.size.toInt} - 1) {
}

*我个人希望这将对使用游戏框架的后代有所帮助，以帮助他们通过迭代来访问表单值：) *

Play框架：如何在错误请求期间再次访问我提交的表单，我的代码无法再次访问列表
