所以我最近一直在玩 MVC 5，我喜欢它。我遇到了一些我认为很容易做到的事情，但最终却在我一天中的几个小时里吃掉了，我一点也不聪明。
基本上我想通过添加我自己的属性来扩展用户模型。我这样做了：
public class IdentityUser : User
{
public IdentityUser()
//: this(String.Empty)
{
}
public IdentityUser(string userName)
: base(userName)
{
}
public string UserId { get; set; }
public string CompanyId { get; set; }
[Required(ErrorMessageResourceType = typeof(Resources.Resources), ErrorMessageResourceName = "RequiredTitle")]
public string Title { get; set; }
[Required(ErrorMessageResourceType = typeof(Resources.Resources), ErrorMessageResourceName = "RequiredFirstName")]
public string Forename { get; set; }
[Required(ErrorMessageResourceType = typeof(Resources.Resources), ErrorMessageResourceName = "RequiredLastName")]
public string Surname { get; set; }
[Required(ErrorMessageResourceType = typeof(Resources.Resources), ErrorMessageResourceName = "RequiredUserName")]
public string UserName { get; set; }
[Required(ErrorMessageResourceType = typeof(Resources.Resources), ErrorMessageResourceName = "RequiredEmail")]
public string Email { get; set; }
public string JobTitle { get; set; }
public string Telephone { get; set; }
public string Mobile { get; set; }
public string Photo { get; set; }
public string LinkedIn { get; set; }
public string Twitter { get; set; }
public string Facebook { get; set; }
public string Google { get; set; }
public string Bio { get; set; }
public string CompanyName { get; set; }
[Required(ErrorMessageResourceType = typeof(Resources.Resources), ErrorMessageResourceName = "RequiredCredentialId")]
public string CredentialId { get; set; }
[Required(ErrorMessageResourceType = typeof(Resources.Resources), ErrorMessageResourceName = "RequiredSecurityCode")]
public string Code { get; set; }
public bool IsLockedOut { get; set; }
public bool IsApproved { get; set; }
public DateTime LastLoginDate { get; set; }
[Display(Name = "Can only edit own assets")]
public bool UserCanEditOwn { get; set; }
[Display(Name = "Can edit assets")]
public bool UserCanEdit { get; set; }
[Display(Name = "Can download assets")]
public bool UserCanDownload { get; set; }
[Display(Name = "Require approval to upload assets")]
public bool UserRequiresApproval { get; set; }
[Display(Name = "Can approve assets")]
public bool UserCanApprove { get; set; }
[Display(Name = "Can synchronise assets")]
public bool UserCanSync { get; set; }
public bool AgreedTerms { get; set; }
}
public class IdentityUserContext : IdentityStoreContext
{
public IdentityUserContext(DbContext db)
: base(db)
{
this.Users = new UserStore<IdentityUser>(this.DbContext);
}
}
public class IdentityUserDbContext : IdentityDbContext<IdentityUser, UserClaim, UserSecret, UserLogin, Role, UserRole>
{
}
User是 EF 中的默认 User 类
namespace Microsoft.AspNet.Identity.EntityFramework
{
public class User : IUser
{
public User();
public User(string userName);
[Key]
public string Id { get; set; }
public string UserName { get; set; }
}
}
我继承了它，因为我在某处读到，如果你想使用自定义类，你必须这样做。无论如何，然后我将我的 Register 模型更改为如下所示：
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; }
public string Title { get; set; }
[Required]
public string Forename { get; set; }
[Required]
public string Surname { get; set; }
[Required]
public string Email { get; set; }
public string CompanyName { get; set; }
[Required]
public string CredentialId { get; set; }
[Required]
public string Code { get; set; }
}
以及看起来像这样的方法：
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
try
{
// Create a profile, password, and link the local login before signing in the user
var companyId = Guid.NewGuid().ToString();
var user = new IdentityUser( model.UserName)
{
CompanyId = companyId,
Title = model.Title,
Forename = model.Forename,
Surname = model.Surname,
Email = model.Email,
CompanyName = model.CompanyName,
CredentialId = model.CredentialId
};
if (await IdentityStore.CreateLocalUser(user, model.Password))
{
await AuthenticationManager.SignIn(HttpContext, user.Id, isPersistent: false);
return RedirectToAction("Setup", new { id = user.CompanyId });
}
else
{
ModelState.AddModelError("", "Failed to register user name: " + model.UserName);
}
}
catch (IdentityException e)
{
ModelState.AddModelError("", e.Message);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
当我尝试注册时，我收到此错误：
Mapping and metadata information could not be found for EntityType 'TestProject.Models.IdentityUser'.
我不知道为什么。
我错过了一步还是什么？
任何帮助将不胜感激
