I am trying to create a view using Student Model, Scaffold template - Create. Create template does not create html helpers for the complex properties. I am new to MVC. Please help.

the view looks like

@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

Use and .İf you want to save database you can entity framework or .和如果你想保存数据库，你可以先实体框架或。

Define controller post method

Answer 2

I had took experiments about inheritance effect on scaffolding to create a view from model without data annotations (primary/foreign keys etc.), and found that your issue may be solved by inherit Gender base class into Person class:

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; }
}

The inheritance includes all Gender member properties into Person class using virtual property reference of Gender class, hence it will generate HTML helpers for Description property:

<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>

NB: Since both Gender and Student class have IsDeleted property with exactly same data type (ie bool ), IsDeleted used in view refers to Student class instead of Gender .
