System.Data.SqlClient.SqlException：列名无效＆＃39; Faculty_Id＆＃39;

Question

控制器：

public async Task<ActionResult> Create([Bind(Include = "Id,Terms,Semester,Sections,Course,CreditHourTheory,CreditHourLab,Labinstructor,Faculty,Rooms,Day,Date,TimeStart,TimeEnd")] TimeTable.Models.TimeTable timetable)    
    {

        if (ModelState.IsValid)
        {
            db.TimeTable.Add(timetable);
            await db.SaveChangesAsync();
            return RedirectToAction("Create");
        }
        return View(timetable);

    }

在视图中，我使用下拉列表从数据库中获取值并将此选定值插入数据库中的另一个表中

@Html.DropDownList("FId", null, String.Empty, new { @class = "form-control input-md cc2", @disabled = "disabled", @required = "" })

型号：

[Table("TimeTable")]
public class TimeTable
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }

    public string Terms { get; set; }
    public string Semester { get; set; }


    public int SectionsId { get; set; }

    [ForeignKey("SectionsId")]
    public Sections Sections { get; set; }

    public int CourseId { get; set; }

    [ForeignKey("CourseId")]
    public Course Course { get; set; }

    public string CreditHourTheory { get; set; }

    public string CreditHourLab { get; set; }

    public int? LabInstructorId { get; set; }
    [ForeignKey("LabInstructorId")]
    public Faculty Labinstructor { get; set; }

    public int FacultyId { get; set; }
    [ForeignKey("FacultyId")]
    public Faculty Faculty { get; set; }

    public int RoomId { get; set; }
    [ForeignKey("RoomId")]
    public Rooms Rooms { get; set; }


    public string Day { get; set; }

    public DateTime Date { get; set; }

    public TimeSpan TimeStart { get; set; }

    public TimeSpan TimeEnd { get; set; }
}
