在 ASP.NET MVC 中使用 Ajax 将数据插入多个表？

Question

我有两张桌子Employees 和Contacts。

员工：

• 员工 ID
• 姓名
• 年龄
• 军人身份
• 婚姻状况

联系人：

• 联系人 ID
• 电话
• 电子邮件
• EmpID //有外键和员工ID

一个员工有很多联系人

我有使用 Ajax 添加具有联系方式的新员工的表单页面。在这段代码中，我刚刚添加了新员工，但我还想同时将联系方式添加到Contacts 表中：

@using Compu_MVC.Models;
@model Tuple<Emp, Cont>

@using (Html.BeginForm())
{
    @Html.ValidationSummary(true)

这是我的EmployeeController：

public class EmployeController : Controller
{
    DynamicEntities db = new DynamicEntities();

    // GET: Employe
    public ActionResult Index() //Record Select 
    {
        List<Employee> EmployeeDatas = db.Employees.OrderByDescending(x => x.EmployeeID).ToList<Employee>();
        return View(EmployeeDatas);           
    }

    [HttpGet]
    public PartialViewResult Create()   //Insert PartialView  
    {
        DynamicEntities db = new DynamicEntities();
        var contrs = db.Departments.ToList();
        ViewData["Department"] = new SelectList(contrs, "DepartmentID", "DepartmentName");
        return PartialView(new Emp());
    }

    [HttpPost]
    public ActionResult Create(Employee emp) // Record Insert  
    {
        DynamicEntities db = new DynamicEntities();
        db.Employees.Add(emp);
        db.SaveChanges();

        return Redirect("Index");
    }
}

我尝试了几种方法，但仍然没有得到解决方案。

谢谢

更好的方法是创建两个模型的视图模型

public class EmployeesContactViewModel
{
    public string Name{ get; set; }
    public int Age{ get; set; } 
    public bool MilitaryStatus{ get; set; }
    public string Phone{ get; set; } 
    public string Email{ get; set; }
    // etc etc rest of your data         
}

然后在 AJAX 请求中根据要求序列化您的数据。例如

var EmployeesContact={  
   Name:$("#Name").val(),
   Age:$("#Age").val(),
   MilitaryStatus:$("#MilitaryStatus").val(),
   Phone:$("#Phone").val(),
   Email:$("#Email").val()
   // etc etc rest of your data 
};
$("#btnCreate").click(function() {
  $.ajax({
    type: "POST",
    url: "/Home/Add",
    data: EmployeesContact,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(response) {
      alert("Hello: " + response.Name + " .\nCurrent Date and Time: " + response.DateTime);
    },
    failure: function(response) {
      alert(response.responseText);
    },
    error: function(response) {
      alert(response.responseText);
    }
  });
});

然后在您的控制器中，使用您的 ViewModel 填充您的实体，然后使用 EF 插入：

[HttpPost]
public ActionResult Add(EmployeesContactViewModel model)
{
     var objEmployee = new Employee{
          Name = model.Name,
          Age= model.Age,
          MilitaryStatus= model.MilitaryStatus,
     };

     var objContact= new Contact{
          Phone= model.Phone,
          Email= model.Email
     };

     //etc for your other entities

     using (var context = new DynamicEntities )
     {
          context.Employee.Add(objEmployee);
          objContact.EmployeeId = Employee.EmployeeId;
          context.Contact.Add(objContact);
          context.SaveChanges();    
     }

     //whatever you want to do here for the result, maybe direct to new controller
     //or return view
     return View();

}
