我有更多关于5个表，学生，课程，部门，申请，注册。
学生在网上申请特定课程，填写表格，提供个人详细信息，包括姓名，地址，联系方式等，并选择部门和特定课程，然后提交表格。
我无法提交该表格，换句话说无法插入学生输入的数据。以下是我的表格。
学生表：
public class Student
{
public int StudentID { get; set; } //PK
public string FirstName { get; set; }
public string LastName { get; set; }
public DateTime DateOfBirth { get; set; }
public string Address { get; set; }
public double PhoneNumber { get; set; }
public string Email { get; set; }
public DateTime AppliedDate { get; set; }
public virtual ICollection<Applied> Applications { get; set; }
}
课程表：
public class Course
{
[DatabaseGenerated(DatabaseGeneratedOption.None)]
public int CourseID { get; set; } //PK
public int DepartmentID { get; set; } //FK
public string CourseName { get; set; }
public string CoursCode { get; set; }
public int NfqLevel { get; set; }
public int CreditHrs { get; set; }
public DateTime StartDate { get; set; }
public DateTime FinishDate { get; set; }
public virtual Department Department { get; set; }
public virtual ICollection<Applied> Applications { get; set; }
}
}
APPLIED TABLE：
public class Applied
{
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int AppliedID { get; set; } //PK
public int StudentID { get; set; } //FK
public int CourseID { get; set; } //FK
public Status? ApplicationStatus { get; set; }
public virtual Student Student { get; set; }
public virtual Course Course { get; set; }
public virtual Enrolment Enrolment { get; set; }
}
MODELVIEW表：
public class Application2
{
public int StudentID { get; set; } //PK
public string FirstName { get; set; }
public string LastName { get; set; }
public DateTime DateOfBirth { get; set; }
public string Address { get; set; }
public double PhoneNumber { get; set; }
public string Email { get; set; }
public DateTime AppliedDate { get; set; }
public int? AppliedID { get; set; }
public int CourseID { get; set; }
}
跟进是控制器部分：
public class Application2Controller : Controller
{
private RegistrarsContext db = new RegistrarsContext();
public ActionResult Index()
{
return View();
}
public ActionResult DepartmentList()
{
var departments = db.Departments.OrderBy(x => x.DpName).ToList();
if (HttpContext.Request.IsAjaxRequest())
{
return Json(new SelectList(
departments,
"DepartmentID",
"DpName"), JsonRequestBehavior.AllowGet
);
}
return View(departments);
}
public ActionResult CourseList(int DepartmentID)
{
var courses = db.Courses.Where(x => x.DepartmentID == DepartmentID).ToList();
if (HttpContext.Request.IsAjaxRequest())
return Json(new SelectList(courses, "CourseID", "CourseName"), JsonRequestBehavior.AllowGet);
return View(courses);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(Application2 application)
{
using (var db = new RegistrarsContext())
if (ModelState.IsValid)
{
var student = new Student { StudentID = application.StudentID, FirstName = application.FirstName, LastName = application.LastName, DateOfBirth = application.DateOfBirth, Address = application.Address, PhoneNumber = application.PhoneNumber, Email = application.Email };
var apply = new Applied { CourseID = application.CourseID, StudentID = application.StudentID };
db.Students.Add(student);
db.Applied.Add(apply);
}
db.SaveChanges();
return View();
}
以下是观看部分：

ViewBag.Title = "Student Appication";
