Question

我不想要一个视图模型。我有一个模型如下

public class Person
    {
        #region private variables
        private string _firstName;
        private string _lastName;
        private string _middleName;
        private Gender _gender;
        #endregion
        #region public properties
        public string FirstName
        {
            get { return _firstName; }
            set { _firstName = value; }
        }
        public string LastName
        {
            get { return _lastName; }
            set { _lastName = value; }
        }
        public string MiddleName
        {
            get { return _middleName; }
            set { _middleName = value; }
        }
        public virtual Gender Gender
        {
            get { return _gender; }
            set { _gender = value; }
        }
        #endregion
    }
 public class Student:Person
    {
        #region private variables
        private int _id;

我正在尝试使用学生模型，脚手架模板 - 创建创建视图。创建模板不会为复杂属性创建html帮助程序。我是MVC的新手。请帮忙。

视图看起来像

@model PracticeWebApp.Models.Student

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Index</h2>

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

    <fieldset>
        <legend>Student</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.DateOfBirth)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.DateOfBirth)
            @Html.ValidationMessageFor(model => model.DateOfBirth)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.IsDeleted)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.IsDeleted)
            @Html.ValidationMessageFor(model => model.IsDeleted)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.FirstName)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.FirstName)
            @Html.ValidationMessageFor(model => model.FirstName)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.LastName)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.LastName)
            @Html.ValidationMessageFor(model => model.LastName)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.MiddleName)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.MiddleName)
            @Html.ValidationMessageFor(model => model.MiddleName)
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

Answer 1

使用主键和外键。如果要保存数据库，可以先实体框架代码或数据库优先< / b>

定义控制器发布方法

Answer 2

我已经对脚手架上的继承效果进行了实验，以便从没有数据注释（主要/外键等）的模型创建视图，并发现您的问题可以通过将Gender基类继承到{{}来解决。 1}} class：

Person

继承使用public class Person : Gender { public String FirstName { get; set; } public String LastName { get; set; } public String MiddleName { get; set; } public virtual Gender Gender { get; set; } }类的虚拟属性引用将所有Gender成员属性包含到Person类中，因此它将为Gender属性生成HTML帮助程序：

Description

注意：由于<div class="editor-label"> @Html.LabelFor(model => model.Description) </div> <div class="editor-field"> @Html.EditorFor(model => model.Description) @Html.ValidationMessageFor(model => model.Description) </div>和Gender类的Student属性具有完全相同的数据类型（即IsDeleted），因此在视图中使用的bool指的是IsDeleted类代替Student。

实体框架+ MVC +脚手架
