Question

我有一个ViewModel，其中包含将分配给Person模型的人员数据，此ViewModel还有一个Address模型，此人有AddressId模型1}}将该人与Address。

相关联

我遇到的问题是，当我将ViewModel映射到Person并将EntityState设置为Modified时，只会显示Person表格已更新和新 Address将被添加（如果已更改），而不是更新。

型号：

public class Address : BaseModel
{
    public int Id { get; set; }

    [Required, Display(Name = "Line One"), MaxLength(128)]
    [Index("IX_AddressCollectiveUniqueness", 1, IsUnique = true)]
    public String LineOne { get; set; }

    [Display(Name = "Line Two"), MaxLength(128)]
    [Index("IX_AddressCollectiveUniqueness", 2, IsUnique = true)]
    public String LineTwo { get; set; }

    [Display(Name = "Line Three"), MaxLength(128)]
    [Index("IX_AddressCollectiveUniqueness", 3, IsUnique = true)]
    public String LineThree { get; set; }

    [Required, MaxLength(32)]
    [Index("IX_AddressCollectiveUniqueness", 4, IsUnique = true)]
    public String Parish { get; set; }

    [Required, MaxLength(16)]
    [Index("IX_AddressCollectiveUniqueness", 5, IsUnique = true)]
    public String Island { get; set; }

    [Required, MaxLength(8)]
    [Index("IX_AddressCollectiveUniqueness", 6, IsUnique = true)]
    public String Postcode { get; set; }

    public virtual ICollection<Person> People { get; set; }
}

public class Person : BaseModel
{
    public int Id { get; set; }

    public int? AddressId { get; set; }

    [Required, Display(Name = "First Name"), MaxLength(32)]
    public String FirstName { get; set; }

    [Display(Name = "Middle Name"), MaxLength(64)]
    public String MiddleName { get; set; }

    [Required, Display(Name = "Last Name"), MaxLength(32)]
    public String LastName { get; set; }

    public virtual Address Address { get; set; }
}

ViewModel：

public class PersonManageVM
{
    public int Id { get; set; }

    public int? AddressId { get; set; }

    public Address Address { get; set; }

    [Required, MaxLength(4)]
    public String Title { get; set; }

    [Required, Display(Name = "First Name"), MaxLength(32)]
    public String FirstName { get; set; }

    [Display(Name = "Middle Name"), MaxLength(64)]
    public String MiddleName { get; set; }

    [Required, Display(Name = "Last Name"), MaxLength(32)]
    public String LastName { get; set; }

}

控制器几乎与生成的更新方法完全相同，它只是设置了实体状态并保存。
