C# 使用ViewModel加载包含来自多个表的值的页面

我想做的是用两个不同表中的信息填充多个标签。当按下submit按钮时，它将点击my Post方法并保存用户输入的信息，并将信息自动填充到db中，但我的Get方法有问题。控制器中的Get方法如下所示：

    [HttpGet]
    public ActionResult AddOrganization(int peopleID = 1)
    {
        var peopleModel = db.People.Include("EmployeeContacts").Single(g => g.PeopleID == peopleID);
        return View("../Setup/AddOrganization", peopleModel);
    }

AddOrganizationViewModel vm  = new AddOrganizationViewModel();
vm.Organizations = new Organizations()
{
someOrganizationProperty = peopleModel.SomeProperty,
};
vm.People = new People()
{
somePeopleProperty = peopleModel.SomeOtherProperty,
};
//etc for the other properties and types in your viewmodel

但是，我有一个viewModel，它看起来像这样，包括此页面的Get和Post方法所需的所有表：

    public class AddOrganizationViewModel
    {
        public MusicStore.Models.Organizations Organizations { get; set; }
        public MusicStore.Models.People People { get; set; }
        public MusicStore.Models.OrganizationOptions OrganizationsOptions { get; set; }
        public MusicStore.Models.EmployeeContacts EmployeeContacts { get; set; }
    }

因此，当第一次加载视图并调用上面的Get方法时，我得到一个错误消息

The model item passed into the dictionary is of type 'System.Data.Entity.DynamicProxies.People_8080C33752A42A0C994331F5015BCCFCEB99B3ECD7AB8CA2BB11ABE67851B81B', but this dictionary requires a model item of type 'MusicStore.ViewModels.AddOrganizationViewModel'.

以下是我的看法：

<h2>AddOrganization</h2>
@model MusicStore.ViewModels.AddOrganizationViewModel

@using (Html.BeginForm("Add", "AddOrganization"))
{
<fieldset>
<legend>CONTACT INFORMATION</legend>
<div class ="editor-label">
    @Html.Label("Organization Name")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.Organizations.OrgName)
</div>
<div class ="editor-label">
    @Html.Label("Phone Number")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.Organizations.OrgPhone)
</div>
<div class ="editor-label">
    @Html.Label("Point of Contact")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.Organizations.OrgPointOfContact)
</div>
<div class ="editor-label">
    @Html.Label("Office Location")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.Organizations.OrgOfficeLocation)
</div>
</fieldset>
<fieldset>
<legend>FIRST EMPLOYEE OF ORGANIZATION</legend>
<div class ="editor-label">
    @Html.Label("Admin First Name")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.People.FirstName)
</div>
<div class ="editor-label">
    @Html.Label("Admin Last Name")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.People.LastName)
</div>
<div class ="editor-label">
    @Html.Label("Admin NID")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.People.NID)
</div>
<div class ="editor-label">
    @Html.Label("Admin SID")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.People.SID)
</div>
 <div class ="editor-label">
     @Html.Label("Admin Email")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.EmployeeContacts.Email)
</div>
 <div class ="editor-label">
    @Html.Label("Admin Phone Number")
</div>
 <div class ="editor-field">
    @Html.TextBoxFor(Model => Model.EmployeeContacts.PrimaryPhone)
</div>

AddOrganization
@模型MusicStore.ViewModels.AddOrganizationViewModel
@使用（Html.BeginForm（“添加”、“添加组织”））
{
联系方式
@Html.Label（“组织名称”）
@Html.TextBoxFor（Model=>Model.Organizations.OrgName）
@Html.Label（“电话号码”）
@Html.TextBoxFor（Model=>Model.Organizations.OrgPhone）
@Html.Label（“联系人”）
@Html.TextBoxFor（Model=>Model.Organizations.OrgPointOfContact）
@Html.Label（“办公地点”）
@Html.TextBoxFor（Model=>Model.Organizations.OrgOfficeLocation）
组织的第一名雇员
@Html.Label（“管理员名”）
@Html.TextBoxFor（Model=>Model.People.FirstName）
@Html.Label（“管理员姓氏”）
@Html.TextBoxFor（Model=>Model.People.LastName）
@Html.Label（“管理员NID”）
@Html.TextBoxFor（Model=>Model.People.NID）
@标签（“管理SID”）
@Html.TextBoxFor（Model=>Model.People.SID）
@Html.Label（“管理电子邮件”）
@Html.TextBoxFor（Model=>Model.EmployeeContacts.Email）
@Html.Label（“管理员电话号码”）
@Html.TextBoxFor（Model=>Model.EmployeeContacts.PrimaryPhone）

当视图只能采用ViewModel类型时，如何通过Get方法将所需信息发送到视图？是否有办法将此信息添加到我的ViewModel？如果有任何帮助或帮助，都将非常有用

 var peopleModel = db.People.Include("EmployeeContacts").Single(g => g.PeopleID == peopleID);

在这种情况下，

peopleModel

的类型是什么

当您直接从数据库返回它时，看起来它还没有被“转换”或“投影”到视图所期望的实际viewmodel中

您可能需要执行以下操作：

    [HttpGet]
    public ActionResult AddOrganization(int peopleID = 1)
    {
        var peopleModel = db.People.Include("EmployeeContacts").Single(g => g.PeopleID == peopleID);
        return View("../Setup/AddOrganization", peopleModel);
    }

AddOrganizationViewModel vm  = new AddOrganizationViewModel();
vm.Organizations = new Organizations()
{
someOrganizationProperty = peopleModel.SomeProperty,
};
vm.People = new People()
{
somePeopleProperty = peopleModel.SomeOtherProperty,
};
//etc for the other properties and types in your viewmodel

设置完所有数据后，可以返回

AddOrganizationViewModel

var peopleModel = db.People.Include("EmployeeContacts").Single(g => g.PeopleID == peopleID);

这不会创建

AddOrganizationViewModel

对象。请在末尾添加

Select

子句，或使用该对象中的数据填充新的viewmodel

这正是我所希望的！非常感谢您的帮助！这正是我所希望的！非常感谢您的帮助！
