数据无法传递到数据库MVC3中

我正在使用MVC3创建一个网站，其中包含必须放入数据库的动态数据。但是我似乎无法找出为什么在我创建之后它不会附加到数据库中。

这是控制器：

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using FYPMvcApplication.Models;
using System.Web.Providers.Entities;

namespace FYPMvcApplication.Controllers
{
public class CreateController : Controller
{
    private bigModel db = new bigModel();

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


    [HttpPost]
    public ActionResult Create(Course course,LearningOut learningout)
    {
        var loc = new LearningOut();
        loc.Outcomes = GetUserOutcomes();

        if (ModelState.IsValid)
        {
            db.Courses.Add(course);
            db.LearningOut.Add(learningout);
            db.SaveChanges();
            return RedirectToAction("Create", new { id = learningout.LearningOutID });
        }

        return View(loc);
    }

    private IList<LearningOut> GetUserOutcomes()
    {
        var outcomesList = new List<LearningOut>();
        return outcomesList;
    }


    public ActionResult NewOutcomeRow(int id)
    {
        var outcome = new LearningOut { LearningOutID = id };
        return View("partial/NewOutcomeRow", outcome);
    }

}
}

型号：

public class LearningOut
{
    public int LearningOutID { get; set; }
    public string LearningOutcomes { get; set; }
    public IList<LearningOut> Outcomes { get; set; }

    public string LearningOutcomesText { get; set; }
    public bool A { get; set; }
    public bool B { get; set; }
    public bool C { get; set; }
    public bool D { get; set; }
    public bool E { get; set; }
    public bool F { get; set; }
    public bool G { get; set; }
    public bool H { get; set; }
    public bool I { get; set; }
}

课程模型：

public class Course
{

    public int CourseID { get; set; }
    public string CourseCode { get; set; }
    public string CourseName { get; set; }
    public string ModuleCode { get; set; }
    public string ModuleName { get; set; }
    public int Year { get; set; }
    public string Prerequisite { get; set; }
    public string References { get; set; }


}

创建视图：

  @model FYPMvcApplication.Models.mainModel
 @{
ViewBag.Title = "Create";
 }

 <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
 <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
 <script type="text/javascript">
$(function () {
    $("#btnAdd").click(function (e) {
        var itemIndex = $("#container input.iHidden").length;
        e.preventDefault();
        var newItem = $("<tr><td><input id='" + itemIndex + "' type='hidden' value='' class='iHidden'  name='[" + itemIndex + "]' /><input type='text' id='" + itemIndex + "' name='[" + itemIndex + "]'/></td><td><input type='checkbox' value='true'  id='" + itemIndex + "' name='[" + itemIndex + "]' /></<td><td><input type='checkbox' value='true'  id='" + itemIndex + "' name='[" + itemIndex + "]' /></td><td><input type='checkbox' value='true'  id='" + itemIndex + "' name='[" + itemIndex + "]' /></td><td><input type='checkbox' value='true'  id='" + itemIndex + "' name='[" + itemIndex + "]' /></td><td><input type='checkbox' value='true'  id='" + itemIndex + "' name='[" + itemIndex + "]' /></td><td><input type='checkbox' value='true'  id='" + itemIndex + "' name='[" + itemIndex + "]' /></td><td><input type='checkbox' value='true'  id='" + itemIndex + "' name='[" + itemIndex + "]' /></td><td><input type='checkbox' value='true'  id='" + itemIndex + "' name='[" + itemIndex + "]' /></td><td><input type='checkbox' value='true'  id='" + itemIndex + "' name='[" + itemIndex + "]' /></td></tr>");
        $("#container").append(newItem);
    });
});
 </script>

编辑。

我的EditorTemplate视图

  @model FYPMvcApplication.Models.mainModel
 @{
Layout = null;
 }
<tr>
<td>
    @Html.HiddenFor(x => x.learningOut.LearningOutID, new { @class = "iHidden" })
    @Html.EditorFor(x => x.learningOut.LearningOutcomesText) </td>
<td>@Html.EditorFor(x => x.learningOut.Outcomes)
    @Html.EditorFor(x => x.learningOut.A)
    @Html.EditorFor(x => x.learningOut.B)
    @Html.EditorFor(x => x.learningOut.C)
    @Html.EditorFor(x => x.learningOut.D)
    @Html.EditorFor(x => x.learningOut.E)
    @Html.EditorFor(x => x.learningOut.F)
    @Html.EditorFor(x => x.learningOut.G)
    @Html.EditorFor(x => x.learningOut.H)
    @Html.EditorFor(x => x.learningOut.I) </td>
    </tr>

部分视图

   @model FYPMvcApplication.Models.mainModel
   @{    Layout = null; }
   <tr>
<td>
    <input type="hidden" id="@(Model.learningOut.LearningOutID)_id" class="iHidden"  name='[@Model.learningOut.LearningOutID].id' />
    <input type='text' id='@(Model.learningOut.LearningOutID)_text'   name='[@Model.learningOut.LearningOutID].text' />
</td>
<td>
    <input type='checkbox' value='true'  id='@(Model.learningOut.LearningOutID)_A' name='[@Model.learningOut.LearningOutID].A'/>
    <input type='checkbox' value='true'  id='@(Model.learningOut.LearningOutID)_B' name='[@Model.learningOut.LearningOutID].B' />

    <input type='checkbox' value='true'  id='@(Model.learningOut.LearningOutID)_C' name='[@Model.learningOut.LearningOutID].C' />

    <input type='checkbox' value='true'  id='@(Model.learningOut.LearningOutID)_D' name='[@Model.learningOut.LearningOutID].D' />

    <input type='checkbox' value='true'  id='@(Model.learningOut.LearningOutID)_E' name='[@Model.learningOut.LearningOutID].E' />

    <input type='checkbox' value='true'  id='@(Model.learningOut.LearningOutID)_F' name='[@Model.learningOut.LearningOutID].F' />

    <input type='checkbox' value='true'  id='@(Model.learningOut.LearningOutID)_G' name='[@Model.learningOut.LearningOutID].G' />

    <input type='checkbox' value='true'  id='@(Model.learningOut.LearningOutID)_H' name='[@Model.learningOut.LearningOutID].H' />

    <input type='checkbox' value='true'  id='@(Model.learningOut.LearningOutID)_I' name='[@Model.learningOut.LearningOutID].I' />
</td>

 </tr>

这是问题所在。我的课程模型似乎能够出现在我的数据库中。但我的学习不能。

编辑：

mainModel查看

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Web;
 using System.Data.Entity;
 namespace FYPMvcApplication.Models
{
public class mainModel
{
    public Course course { get; set; }
    public LearningOut learningOut { get; set; }
}
}

包括mainmodel＆amp;更新了我的创建视图。

我认为，您可以将控制器更改为.. 

sub my_sub {
  my $v1 = shift;
  my $v2 = shift;

  print "The value of the first passed variable is: $v1";
  print "The value of the first passed variable is: $v1";
}
