Question

我正在尝试C＃MVC，我偶然发现了以下问题。我正在玩一个小项目，这是一种任务管理工具。此时我有2个（用户，任务）模型和相应的控制器和一组视图。用户控制器有一种方法＆＃39;创建＆＃39;这显然是基于从表单收到的数据创建一个新用户。创建用户时，应自动为他创建任务。这是我的用户控制器创建/注册方法：

public ActionResult Create()
    {
        return View();
    }


    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "userId,dateCreated,dateRemoved,level,firstName,lastName,login,emailAddress,password")] User user)
    {
        user.dateCreated = DateTime.Now;
        if (ModelState.IsValid)
        {
            db.User.Add(user);
            db.SaveChanges();

            return RedirectToAction("Create", "Tasks", new { Id = user.userId });


           //return RedirectToAction("Index");
        }

        return View(user);
    }

这是任务控制器的Create Task方法

public ActionResult Create()
    {
        return View();
    }


    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "taskId,dateCreated,dateAssigned,userId,assigneeId,taskCategory,taskType,taskPriority,taskStatus,taskName,dateDue,dateClosed,Comments")] Task task, int? Id)
    {
        task.dateCreated = DateTime.Now;

        if (Id != null)
        {
            task.userId = (int)Id;
            task.dateAssigned = DateTime.Now;
            task.dateCreated = DateTime.Now;
            task.dateDue = DateTime.Now.AddDays(7);
            task.taskCategory = taskCategory.assigned;
            task.taskType = taskType.System_Induction;
            task.assigneeId = 2;
            task.taskPriority = taskPriority.Low;
            task.taskName = "Iduction to TaskManagementTool";
            task.Comments = "Please go through the following training materials:";
            task.taskStatus = taskStatus.Assigneed;



            if (ModelState.IsValid)
            {

                db.Tasks.Add(task);


                db.SaveChanges();

                ViewBag.TaskAssignedNotification = "Hello " + Session["login"].ToString() + " you have new task assigned" ;


                switch (Session["level"].ToString())
                { 
                    case "Basic":
                        return RedirectToAction("LoggedAsBasic", "Home");
                        break;

                    default:
                        return RedirectToAction("LoggedAsBasic", "Home");
                }

                //return RedirectToAction("Index", "Home");
            }
        }
        else
        {
            task.userId = Int32.Parse(Session["userId"].ToString());
            task.taskStatus = taskStatus.Created;


            if (Session["level"].ToString() == "Assigner" && task.taskCategory == taskCategory.assigned)
            {
                task.dateAssigned = DateTime.Now;


            }





            if (Session["level"].ToString() == "Basic")
                task.taskCategory = taskCategory.own;

            if (ModelState.IsValid)
            {

                db.Tasks.Add(task);


                db.SaveChanges();


                return RedirectToAction("TasksIndex");
            }
        }
        return View(task);
    }

在创建新用户时，应将新用户ID传递给任务控制器的Create方法，并且应为新用户创建预定义任务（if if（Id！= null）），而无需使用HTML打开Create视图形成。 Unfortunatley我无法从用户控制器调用任务控制器的Create方法。充其量我最终会创建要填充的任务。你们能帮帮我解决这个问题吗？

在这种情况下我需要的是使用users / create action方法创建的新任务对象，以便与用户对象一起使用，因此我不需要指向任何其他控制器/ actionresult来创建任务。

[HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "userId,dateCreated,dateRemoved,level,firstName,lastName,login,emailAddress,password")] User user, Task task)
    {
        user.dateCreated = DateTime.Now;
        if (ModelState.IsValid)
        {
            db.User.Add(user);
            db.SaveChanges();

            task.userId = 2;
            task.dateAssigned = DateTime.Now;
            task.dateCreated = DateTime.Now;
            task.dateDue = DateTime.Now.AddDays(7);
            task.taskCategory = taskCategory.assigned;
            task.taskType = taskType.System_Induction;
            task.assigneeId = user.userId;
            task.taskPriority = taskPriority.Low;
            task.taskName = "Iduction to TaskManagementTool";
            task.Comments = "Please go through the following training materials:";
            task.taskStatus = taskStatus.Assigneed;

            if (ModelState.IsValid) {


                db.Tasks.Add(task);
                db.SaveChanges();



            }


           return RedirectToAction("Index");
        }

        return View(user);
    }

重定向到另一个控制器方法直接避免视图
