INSERT语句与FOREIGN KEY约束错误冲突

Question

嗨,我收到了这个错误

INSERT语句与FOREIGN KEY约束"FK_dbo.AspNetUsers_dbo.Contacts_ContactID"冲突.

冲突发生在数据库"aspnet-COGMakati-20140119015553",表"dbo.Contacts",列'ContactID'中.

该语句已终止.

我正在使用Entity Framework和MVC 5的IdentityUser,所以我真的迷失了我正在做的事情:

这就是我想要填充的内容:

public class User : IdentityUser
{
    [Required]
    [Display(Name = "First Name")]
    public string FirstName { get; set; }

    [Required]
    [Display(Name = "Last Name")]
    public string LastName { get; set; }

    [Required]
    public string Email { get; set; }

    public string Birthday { get; set; }
    [Display(Name = "Referred By")]
    public string LifegroupPreference { get; set; }
    [Display(Name = "Civil Status")]
    public string CivilStatus { get; set; }

    public int EducationID { get; set; }
    public int WorkID { get; set; }
    public int ContactID { get; set; }
    public int FamilyID { get; set; }
    public int SpiritualID { get; set; }
    public int GrowthMilestoneID { get; set; }

    [ForeignKey("EducationID")]
    public virtual Education Education { get; set; }
    [ForeignKey("WorkID")]
    public virtual Work Work { get; set; }
    [ForeignKey("ContactID")]
    public virtual Contact Contact { get; set; }
    [ForeignKey("FamilyID")]
    public virtual Family Family { get; set; }
    [ForeignKey("SpiritualID")]
    public virtual Spiritual Spiritual { get; set; }
    [ForeignKey("GrowthMilestoneID")]
    public virtual GrowthMilestone GrowthMilestone { get; set; }
}

我看到它的方式,Contact是在用户制作之前创建的.我不知道为什么会发生这种情况,因为当不使用IdentityUser此代码时,填充它就好了.

现在这是Register方法:

public async Task<ActionResult> Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = model.GetUser();
        var result = await UserManager.CreateAsync(user, model.Password);
        if (result.Succeeded)
        {
            var idManager = new IdentityManager();
            idManager.AddUserToRole(user.Id, "User");

            await SignInAsync(user, isPersistent: false);
            return RedirectToAction("ViewAllMembers", "Home");
        }
        else
        {
            AddErrors(result);
        }
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

您可能正在尝试使用不存在的外键访问或插入.转到您的dbo.Contacts表并使用该键查找记录.您将在表格中找不到包含该密钥的记录.您需要使用该密钥创建记录或使用另一个(现有)密钥.
