更新实体框架中的嵌套对象

最近我发现 EF 不更新嵌套对象。几天来，我试图弄清楚如何做到这一点，但不幸的是我被这个问题困住了。

我有对象

public class ProjectEntity : AuditableEntity<int>
{

    public string CustumerCompany { get; set; }
    public string CustomerRepresentative { get; set; }

    public string ProjectTitle { get; set; }
    public string WwsNumber { get; set; }

    [ForeignKey("ParentProjectId")]
    public virtual ProjectEntity ParentProject { get; set; }

    public int? ParentProjectId { get; set; }

    public virtual ICollection<ProjectServicesEntity> Service { get; set; }
}

public class ProjectServicesEntity : AuditableEntity<int>
{
    /// <summary>
    /// Service Number
    /// </summary>
    public int Number …

	self.CustumerCompany = ko.observable(project ? project.CustumerCompany : "");
	self.CustomerRepresentative = ko.observable(project ? project.CustomerRepresentative : "");
	self.ProjectTitle = ko.observable(project ? project.ProjectTitle : "");

我遇到了JavaScript问题.我想要一个脚本,在退出整个网站时弹出一条带有问题的消息,如果访问者回答"否"网页关闭,如果他回答"是",他将被重定向到另一个页面.我在http://www.pgrs.net/2008/01/30/popup-when-leaving-website/找到了一个例子,但似乎它对我不起作用.我找不到任何解决方案.请检查我的代码并告诉我也许我做错了什么？这是我的源代码.

也许有人会看到一个问题.
