java - Playframework 从嵌套 Controller 加载表单

我想将表单从嵌套 Controller 传递到 View 。

这是我的设置:

app
 |
 --controllers
       |
       --appointment
              |
              -- Appointment.java


 |
 -- views
      |
      -- appointment
              |
              -- create.scala.html

路线:

# Appointment
GET /appointment/create         controllers.appointment.Appointment.create()
POST /appointment               controllers.appointment.Appointment.validate()

预约类(class):

public class Appointment extends Controller {

public static Result create() {
    List<Procedure> procedures = Procedure.find.all();
    List<Employee> doctors = Employee.find.where().eq("role", "doctor").findList();
    return ok(create.render(Form.form(CreateAppointment.class), procedures, doctors));

}

public static Result validate(){
    Form<CreateAppointment> registerForm = Form.form(CreateAppointment.class).bindFromRequest();

        return badRequest(create.render(registerForm));
}

public static Result edit(Integer id) {
    return TODO;
}

public static Result delete(Integer id) {
    return TODO;
}

public static Result all() {
    return TODO;
}

public static class CreateAppointment {

    public Date endDate;
    public Date startDate;

    public String reason;

    public String validate() {
        if (startDate.after(endDate))
            return "End date must be after start Date";

        return null;
    }

}

}

创建.scala.html

@(form: Form[controllers.appointment.routes.Appointment.CreateAppointment],procedures: List[Procedure],doctors: List[Employee])
    <html>
    <head> </head>
    <body>

    @helper.form(controllers.appointment.routes.Appointment.create) {

问题出在这里 -> form: Form[__ROUTE___]问题是我不知道如何正确传递 CrateAppointment。

我已经尝试过:

controllers.appointment.routes.Appointment.CreateAppointment
Appointment.CreateAppointment
ppointment.Appointment.CreateAppointment

我收到错误

[error] MyPath\app\views\appointment\create.scala.html:1: type CreateAppointment is not a member of controllers.appointment.ReverseAppointment

最佳答案

在 PlayFramework 中， Controller 中的每个包都有自己的路由包。例如，您要查找的 url 是以下两个路由之一:

controllers.appointment.routes.Appointment.create()
controllers.appointment.routes.Appointment.validate()
