我的项目有两个模型类，
data.frame和
public class BookModel
{
public Int64 ISBN { get; set; }
public DateTime AddedDate { get; set; }
public bool isactive { get; set; }
public int Quantity { get; set; }
public int? FormatID { get; set; }
public virtual FormatModel Format { get; set; }
}
我想在public class FormatModel
{
public FormatModel()
{
Books = new HashSet<BookModel>();
}
public int ID { get; set; }
public string Value { get; set; }
public virtual ICollection<BookModel> Books { get; }
}
文件中创建一个模态，以在指定格式不存在时添加新格式。
如何为我的模式创建一个“提交”按钮以在Create.cshtml中添加格式？
这是我的观点：
FormatModel点击“创建格式”按钮后。它为@model RookBookMVC.Models.BookModel
@{
ViewBag.Title = "Create";
Layout = "~/Views/Shared/_Layout.cshtml";
ViewBag.ReturnUrl = "/Book/Create";
}
<h2>Create</h2>
@using (html.beginform("Create","Book",FormMethod.Post))
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>BookModel</h4>
<hr />
@Html.ValidationSummary(true,"",new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(model => model.FormatID,"FormatID",htmlAttributes: new { @class = "control-label col-md-2" })
<div class="input-group col-md-10">
@Html.DropDownList("FormatID",null,"Select Book Format",htmlAttributes: new { @class = "form-control" })
<div class="input-group-append">
<button type="button" class="btn btn-secondary" data-toggle="modal" data-target="#exampleModalCenter">

</div>
@Html.ValidationmessageFor(model => model.FormatID,new { @class = "text-danger" })

}

<div class="modal-body">

}
<div>
@Html.actionLink("Back to List","Index")

@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
返回false，并且不向我的数据库添加任何数据
如何制作“创建格式”按钮以创建新的格式实体并将其保存在数据库中？
对于其他，我需要通过一个页面创建两个模型
