Question

我将用户详细信息分成了自己的表配置文件，并带有ApplicationUser的外键，但现在我的插入失败。

所以我得到了以下表格：

AspNetUsers 
{
    Id
    UserName
    PasswordHash
    SecurityStamp
    Descriminator
}

和

Profiles
{
    Id
    FirstName
    LastName
    Email
    AspNetUser_Id
}

所以我通过添加如下额外字段来更改 RegisterViewModel ：

public class RegisterViewModel
{
    [Required]
    [Display(Name = "User name")]
    public string UserName { get; set; }

    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirm password")]
    [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }

    [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; }
}

...并将“个人档案”表中的字段合并到 Register.cshtml 中，我想将模型中的信息存储到两个表中。所以我的AccountController.Register看起来像这样：

    //
    // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {

            var user = new ApplicationUser() { UserName = model.UserName };
            var result = await UserManager.CreateAsync(user, model.Password);

            if (result.Succeeded)
            {
                var profile = new Profile
                {
                    FirstName = model.FirstName,
                    LastName = model.LastName,
                    EMail = model.EMail,
                    User = user
                };

                var db = new DecoupleDb();
                db.Profiles.Add(profile);
                db.SaveChanges();

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

但现在我一直在

上收到错误

db.SaveChanges();

错误说我试图违反AspNetUsers表的主键

＆＃34;违反PRIMARY KEY约束＆＃39; PK_dbo.AspNetUsers＆＃39;。无法在对象＆＃39; dbo.AspNetUsers＆＃39;中插入重复键。重复键值为（372775e0-bad5-452f-b65c-cd9bf7b80b34）。该声明已被终止。＆＃34;

我无法理解为什么，因为它只是一个外键，因此当我添加配置文件时，不应该创建AspNetUser，或者我认为。

有人看到修复？

我找到了答案。我必须存储新用户，然后将其取回并填充配置文件。像这样：

        if (ModelState.IsValid)
        {
            var user = new ApplicationUser {UserName = model.UserName};
            var result = await UserManager.CreateAsync(user, model.Password);

            if (result.Succeeded)
            {
                var newUser = db.ApplicationUsers.Find(user.Id);

                var profile = new Profile
                {
                    FirstName = model.FirstName,
                    LastName = model.LastName,
                    Email = model.Email,
                    Identity = newUser,
                };

                db.Profiles.Add(profile);
                db.SaveChanges();

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

将IdentityUser与UserProfile分开
