如何以一种形式发布两个或多个模型？

我正在为一个项目开发互联网课程计划应用程序。该课程计划是根据以下模型构建的（使用数据库优先方法中的实体框架生成）：

public partial class Subject
{
    public int Id { get; set; }
    public string Hour { get; set; }
    public string Name { get; set; }
    public int DayId { get; set; }
    [Required]
    public int PlanId { get; set; }

    public virtual Day Day { get; set; }
    public virtual Plan Plan { get; set; }
}

public partial class Plan
{
    public Plan()
    {
        this.Przedmiot = new HashSet<Subjects>();
    }

    public int Id { get; set; }
    [Required]
    public string Name { get; set; }

    public virtual ICollection<Subject> Subject { get; set; }
}

I have no problems with displaying both models in one View, but I can't seem to figure out how to post both models to database when creating new plan. I want my View to look something like this:

所以我的问题是这里最好的方法是什么，以及如何在数据库的计划表中创建一条记录，以及在这个视图中链接到它的许多主题记录。

Edit:根据要求使用我的显示视图进行代码（省略了不必要的部分，因为它相当长）：

@model IEnumerable<Lesson_plan.DAL.Subject>
<table style="border: 1px solid black; margin: 40px; width: 100%;">
    <tr>
        <th>Hours</th>
        <th>Monday</th>
        <th>Tuesday</th>
        <th>Wednesday</th>
        <th>Thursday</th>
        <th>Friday</th>
        <th>Saturday</th>
        <th>Sunday</th>
    </tr>

    @{
        if (Model != null)
        {
            var r = 1;
            var t = 1;
            List<string> hours = new List<string>();
            foreach (var subject in Model)
            {
                if (!hours.Contains(subject.Hour))
                {
                    <tr>
                        <td>
                            <textarea>    
                            @Html.DisplayFor(modelItem => subjest.Hour)
                            @{ hours.Add(subject.Hour); }
                            </textarea>
                        </td>

                        <td>
                            <textarea>  
                            @foreach (var subjectName in Model)
                            {
                                if (subjectName.Day.DayOfTheWeek.Equals("Monday") &&
                                    subject.Hour.Equals(subjetName.Hour))
                                {
                                    @Html.DisplayFor(modelItem => subject.Name)
                                }
                            }   
                            </textarea>
                        </td>

//and so on for every day 

                        }
                    </tr>
                    r++;
                }
            }
        }
    }
</table>

我的 Controller 类的代码（我使用 Create 方法做了一些实验，但我在这里发布原始方法）：

namespace Lesson_plan.Controllers
{
    public class PlansController : Controller
    {
        private readonly LessonPlanEntities db = new LessonPlanEntities();

        // GET: Plans
        public ActionResult Index()
        {
            var plans = db.Plan.ToList();
            return View(plans);
        }

        // GET: Plans/Details/5
        public ActionResult Details(int? id)
        {
            if (id == null)
                return Create();
            var subjects = db.Subject.
                Where(x => x.PlanId == id).
                OrderByDescending(x => x.Hour).ToList();
            if (subjects.Count > 0)
                ViewBag.Title = subjects[0].Plan.Name;
            return View(subjects);
        }

        // GET: Plans/Create
        public ActionResult Create()
        {
            return View();
        }

        [HttpPost]
        public ActionResult Create(Plan plan)
        {
            if (ModelState.IsValid)
            {
                db.Plan.Add(plan);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(plan);
        }

        // GET: Plans/Edit/5
        public ActionResult Edit(int? id)
        {
            if (id == null)
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            var plan = db.Plan.Find(id);
            if (plan == null)
                return HttpNotFound();
            return View(plan);
        }

        // POST: Plans/Edit/5
        // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
        // more details see http://go.microsoft.com/fwlink/?LinkId=317598.
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Edit([Bind(Include = "Id,Nazwa")] Plan plan)
        {
            if (ModelState.IsValid)
            {
                db.Entry(plan).State = EntityState.Modified;
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(plan);
        }

        // GET: Plans/Delete/5
        public ActionResult Delete(int? id)
        {
            if (id == null)
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            var plan = db.Plan.Find(id);
            if (plan == null)
                return HttpNotFound();
            return View(plan);
        }

        // POST: Plans/Delete/5
        [HttpPost]
        [ActionName("Delete")]
        [ValidateAntiForgeryToken]
        public ActionResult DeleteConfirmed(int id)
        {
            var plan = db.Plan.Find(id);
            db.Plan.Remove(plan);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        protected override void Dispose(bool disposing)
        {
            if (disposing)
                db.Dispose();
            base.Dispose(disposing);
        }
    }
}

Edit2使用表单创建视图的代码：

@model Lesson_plan.DAL.Plan

@using (Html.BeginForm("Create", "Plans"))
{
    <div>
        @Html.LabelFor(plan => plan.Name)<br/>
        @Html.TextAreaFor(plan => plan.Name)
    </div>
    <table style="border: 1px solid black; margin: 40px; width: 100%;">
        <tr>
            <th>Hours</th>
            <th>Monday</th>
            <th>Tuesday</th>
            <th>Wednesday</th>
            <th>Thursday</th>
            <th>Friday</th>
            <th>Saturday</th>
            <th>Sunday</th>
        </tr>
            @{
                for (int i = 0; i < 7; i++)
                {
                    <tr>  
                        //what sould i put here ?                    
                        <td><textarea></textarea></td>
                        <th><textarea></textarea></th>
                        <th><textarea></textarea></th>
                        <th><textarea></textarea></th>
                        <th><textarea></textarea></th>
                        <th><textarea></textarea></th>
                        <th><textarea></textarea></th>
                        <th><textarea></textarea></th>
                    </tr>
                }
            }
    </table>
    <p>
        <a type="button" class="btn btn-info" [email protected] /cdn-cgi/l/email-protection("Index")>Back</a>
        <input type="submit" value="Create"/>
    </p>
}

最好的方法是设计一个 ViewModel 类，它可以保存表单上需要提交的计划和/或主题的所有数据。

在接收此 ViewModel 的操作方法中，您可以分离数据，并基于此执行将其存储在数据库中所需的任何插入和/或更新。

只有控制器应该了解您的数据库类。 ViewModel 和数据库对象之间的所有映射都应该由控制器完成，并且 View 不应该受此困扰或阻碍。
