身份注册用户

Question

我的MVC 4应用程序中的注册用户有问题。

我已经使用Identity框架创建了一个CMS，如果我直接在数据库中创建用户，则登录工作正常。

用户以“管理员”身份登录，并且可以访问我的“注册”页面以创建新用户。

问题是当我尝试提交注册表时，它说的是：

一个或多个实体的验证失败。有关详细信息，请参阅“EntityValidationErrors”属性。

我试过调试，似乎正确地获取所有输入。

我对所有这些东西都很陌生，所以我很抱歉，如果我的代码很乱。

希望你们亲们可以帮助新手：）

我的代码如下所示：

// POST: /Account/Register
    [HttpPost]
    [Authorize(Roles = "Admin")]
    [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)
            {
                await SignInAsync(user, isPersistent: false);
                return RedirectToAction("Index", "Home");
            }
            else
            {
                AddErrors(result);
            }
        }

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

这是我的帐户模型
