在mvc中一次保存多个视图模型数据

我有5个class：

1）EmployeeMainTable.cs（Employeeid是主键，employee id是其余类的外键）

2）EmployeeFamilyTable.cs

3）previousEmployeement.cs

4）employeeaddress.cs

5）employeeEducation.cs

每个类包含相应的属性在此输入代码

现在我要为每个类创建我创建了5个视图来输入数据，每个视图都包含提交按钮以转到下一个视图

我的问题是，当我在上一个视图中单击“完成”按钮时，我想立即保存所有模型。

一旦使用mvc 4，请理解问题

我试过以下结果：

@model SecondStep @using(Html.BeginForm("ThirdStep", "controllerName", FormMethod.Post)) { @Html.HiddenFor(model => ViewBag.FirstStepModel.Value) @Html.EditorFor(model => model.Value)  } 

CS1963: An expression tree may not contain a dynamic operation

得到错误

 @Html.HiddenFor(model => ViewBag.FirstStepModel.Value) Line 13: { Line 14: Line 15: @Html.HiddenFor(model=>ViewBag.FirstStepModel) this line giving error Line 16: @Html.EditorFor(model => model.SecondStepProp) Line 17: 

Answer 1

您应该将以前的视图模型多次传递到“下一个”视图，因此单击“完成”按钮时，您可以检索所有模型（在控制器中）以在最后创建。 （别忘了把你的模特放在post里）

UPDATE1：

为什么在控制器上需要GET和POST方法？

USPDATE2：示例

**案例1：如果您有多个视图模型**

调节器

 [HttpGet] public ActionResult FirstStep() { return View(new FirstStepModel()); } [HttpPost] public ActionResult SecondStep(FirstStepModel firstStepModel) { ViewBag.FirstStepModel = firstStepModel; return View(new SecondStepModel()); } [HttpPost] public ActionResult ThridStep(FirstStepModel firstStepModel, SecondStepModel secondStepModel) { ViewBag.FirstStepModel = firstStepModel; ViewBag.SecondStepModel = secondStepModel; return View(new ThirdStepModel()); } [HttpPost] public ActionResult FourthStep(FirstStepModel firstStepModel, SecondStepModel secondStepModel, ThirdStepModel thirdStepModel) { ViewBag.FirstStepModel = firstStepModel; ViewBag.SecondStepModel = secondStepModel; ViewBag.ThirdStepModel = thirdStepModel; return View(new FourthStepModel())); } [HttpPost] public ActionResult FifthStep(FirstStepModel firstStepModel, SecondStepModel secondStepModel, ThirdStepModel thirdStepModel, FourthStepModel fourthStepModel) { ViewBag.FirstStepModel = firstStepModel; ViewBag.SecondStepModel = secondStepModel; ViewBag.ThirdStepModel = thirdStepModel; ViewBag.FourthStepModel = fourthStepModel; return View(new FinalStepModel()); } [HttpPost] public ActionRestul Finish(FirstStepModel firstStepModel, SecondStepModel secondStepModel, ThirdStepModel thirdStepModel, FourthStepModel fourthStepModel, FifthStepModel fifthStepModel) { // DB Save ? } 

观点 FirstStep：

 @model FirstStep @using(Html.BeginForm("SecondStep", "controllerName", FormMethod.Post)) { @Html.EditorFor(model => model.Value)  } 

第二步：

 @model SecondStep @using(Html.BeginForm("ThirdStep", "controllerName", FormMethod.Post)) { @Html.HiddenFor(model => ViewBag.FirstStepModel.Value) @Html.EditorFor(model => model.Value)  } 

ThirdStep：

 @model ThirdStep @using(Html.BeginForm("FourthStep", "controllerName", FormMethod.Post)) { @Html.HiddenFor(model => ViewBag.FirstStepModel.Value) @Html.HiddenFor(model => ViewBag.SecondStepModel.Value) @Html.EditorFor(model => model.Value)  } 

FourthStep：

 @model FourthStep @using(Html.BeginForm("FifthStep", "controllerName", FormMethod.Post)) { @Html.HiddenFor(model => ViewBag.FirstStepModel.Value) @Html.HiddenFor(model => ViewBag.SecondStepModel.Value) @Html.HiddenFor(model => ViewBag.ThirdStepModel.Value) @Html.EditorFor(model => model.Value)  } 

FifthStep：

 @model FifthStep @using(Html.BeginForm("Finish", "controllerName", FormMethod.Post)) { @Html.HiddenFor(model => ViewBag.FirstStepModel.Value) @Html.HiddenFor(model => ViewBag.SecondStepModel.Value) @Html.HiddenFor(model => ViewBag.ThirdStepModel.Value) @Html.HiddenFor(model => ViewBag.FifthStepModel.Value) @Html.EditorFor(model => model.Value)  } 

案例2：单一视图模型 Carefull：为了使其工作，您将需要（取决于您的模型的复杂性）模型的ModelBinder

 [HttpGet] public ActionResult FirstStep() { return View("FirstStep", new Model()); } [HttpPost] public ActionResult SecondStep(Model model) { return View("SecondStep", model); } [HttpPost] public ActionResult ThridStep(Model model) { return View("ThirdStep", model); } [HttpPost] public ActionResult Finish(Model model) { // DB Save ? }

第一步：

 @model Model @using(Html.BeginForm("SecondStep", "controllerName", FormMethod.Post)) { @Html.EditorFor(model => model.Step1Value)  } 

第二步：

 @model Model @using(Html.BeginForm("ThirdStep", "controllerName", FormMethod.Post)) { @Html.HiddenFor(model => model.Step1Value) @Html.EditorFor(model => model.Step2Value)  } 

ThirdStep：

 @model Model @using(Html.BeginForm("Finish", "controllerName", FormMethod.Post)) { @Html.HiddenFor(model => model.Step1Value) @Html.HiddenFor(model => model.Step2Value) @Html.EditorFor(model => model.Step3Value)  }
