Question

我正在学习 play 框架

Play Framework

它在此代码的第一行给出错误。

Form<Task> filledForm = taskForm.bindFromRequest();
if(filledForm.hasErrors()) {
return badRequest(
  views.html.index.render(Task.all(), filledForm)
);
} else {
Task.create(filledForm.get());
return redirect(routes.Application.tasks());  
}
}

Answer 1

尝试在类中注入(inject)表单工厂

@Inject
FormFactory formFactory;

并在行动中尝试这样

Form<Task> filledForm = formFactory.form(Task.class).bindFromRequest();
