实体类型ApplicationUser不是当前上下文的模型的一部分 [英] The entity type ApplicationUser is not part of the model for the current context

问题描述

我正在从Identity 1.0.0迁移到Identity 2.0.1之后，这个文章

，并且生成的迁移代码与新的IdentityUser无关。它不添加新列。

所以我做了一个新项目，再次尝试，但迁移代码是空的。

要解决此问题，我直接在SQL Server中进行了编辑，并在我的解决方案中再次导入了我的数据库。

现在我的 AspNetUser 与我的 IdentityUser 您可以看到

IdentityUser

  public virtual int AccessFailedCount {get;组; } 
 
 public virtual ICollection< TClaim>索赔{get; } 
 
 public virtual string Email {get;组; } 
 
 public virtual bool EmailConfirmed {get;组; } 
 
 public virtual TKey Id {get;组; } 
 
 public virtual bool LockoutEnabled {get;组; } 
 
 public virtual DateTime？ LockoutEndDateUtc {get;组; } 
 
 public virtual ICollection< TLogin>登录{get; } 
 
 public virtual string PasswordHash {get;组; } 
 
 public virtual string PhoneNumber {get;组; } 
 
 public virtual bool PhoneNumberConfirmed {get;组; } 
 
 public virtual ICollection< TRole>角色{get; } 
 
 public virtual string SecurityStamp {get;组; } 
 
 public virtual bool TwoFactorEnabled {get;组; } 
 
 public virtual string UserName {get;组; 
  

IdentityUser.cs

  public class ApplicationUser：IdentityUser 
 {
 public bool Has_accepted_policy {get;组; } 
 public int user_type_id {get;组; } 
} 
 
 public class ApplicationDbContext：IdentityDbContext< ApplicationUser> 
 {
 public ApplicationDbContext（）
：base（DefaultConnection）
 {
 
} 
} 
  

AspNetUser

  public string Id {get;组; 
 
 [必需] 
 [StringLength（256）] 
 public string UserName {get;组; } 
 
 public string PasswordHash {get;组; } 
 
 public string SecurityStamp {get;组; 
 
 [StringLength（256）] 
 public string Email {get;组; } 
 
 public bool EmailConfirmed {get;组; } 
 
 public bool Is_Active {get;组; 
 
 [必需] 
 [StringLength（128）] 
 public string Discriminator {get;组; } 
 
 public int？ user_type_id {get;组; } 
 
 public bool Has_accepted_policy {get;组; } 
 
 public string PhoneNumber {get;组; } 
 
 public bool PhoneNumberConfirmed {get;组; } 
 
 public bool TwoFactorEnabled {get;组; } 
 
 public DateTime？ LockoutEndDateUtc {get;组; } 
 
 public bool LockoutEnabled {get;组; } 
 
 public int AccessFailedCount {get;组; } 
 
 ...其他虚拟属性
  

当我尝试注册一个用户我有以下异常

实体类型ApplicationUser不是当前上下文模型的一部分

在这一行

  IdentityResult result = await UserManager.CreateAsync （user，model.Password）; 
  

我的 startup.Auth.cs

  UserManagerFactory =（）=> new UserManager< ApplicationUser>（new UserStore< ApplicationUser>（））; 
  

在我的 AccountController 中，我声明了我的 UserManager 这样

  public AccountController（）
：this（Startup.UserManagerFactory（） Startup.OAuthOptions.AccessTokenFormat）
 {
} 
 
 public AccountController（UserManager< ApplicationUser> userManager，
 ISecureDataFormat&AuthenticationTicket> accessTokenFormat）
 {
 UserManager = userManager; 
 AccessTokenFormat = accessTokenFormat; 
} 
 
 public UserManager< ApplicationUser> UserManager {get;私人集合$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ 
 
 
 / code> class，它在迁移之前用起来很好。 
 
 
 
  CodePlex还有一个类似的问题标记为固定的，但他们没有给出解决方案
 
 
 
有谁知道如何解决这个问题？
 
 
 
 编辑 
 
 
 
确保在编辑SQL数据库时没有发生任何错误。我创建了另一个项目并生成了一个Identity数据库，我更改了该数据库的连接字符串，我仍然有相同的错误。
 
 
 
 解决方案 / p> 
 
 
当我编辑我的数据库时，我没有注意到，在Identity 2.0.0中，他们更改了 User_Id  code> UserId 在 AspUserClaims 表中。做完之后，我有同样的错误，但是我做了tschmit007所说的关于将 ApplicationDbContext 添加到 UserStore 构造函数中，现在它的作品
  UserManagerFactory =（）=> new UserManager< ApplicationUser>（new UserStore< ApplicationUser>（new ApplicationDbContext（）））; 
  
 
 
解决方案
对我来说似乎错过了一个上下文instanciation： / p> 
 
 
  UserManagerFactory =（）=> new UserManager< ApplicationUser>（new UserStore< ApplicationUser>（））; 
  
应该是
 code> UserManagerFactory =（）=> new UserManager< ApplicationUser>（new UserStore< ApplicationUser>（new ApplicationDbContext（）））; 
  
 
I'm migrating from Identity 1.0.0 to Identity 2.0.1 following this article

and the migrations code generated is nothing about the new IdentityUser. It doesn't add the new columns. 

So I made a new project and tried again but the migrations codes is empty. 

To fix that problem, I did the edits directly in SQL Server and imported my database again in my solution. 

Now my AspNetUser is exactly the same as my IdentityUser as you can see

IdentityUser
public virtual int AccessFailedCount { get; set; }

public virtual ICollection<TClaim> Claims { get; }

public virtual string Email { get; set; }

public virtual bool EmailConfirmed { get; set; }

public virtual TKey Id { get; set; }

public virtual bool LockoutEnabled { get; set; }

public virtual DateTime? LockoutEndDateUtc { get; set; }

public virtual ICollection<TLogin> Logins { get; }

public virtual string PasswordHash { get; set; }

public virtual string PhoneNumber { get; set; }

public virtual bool PhoneNumberConfirmed { get; set; }

public virtual ICollection<TRole> Roles { get; }

public virtual string SecurityStamp { get; set; }

public virtual bool TwoFactorEnabled { get; set; }

public virtual string UserName { get; set; }
IdentityUser.cs
public class ApplicationUser : IdentityUser
{
    public bool Has_accepted_policy { get; set; }
    public int user_type_id { get; set; }
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {

    }
}
AspNetUser
public string Id { get; set; }

[Required]
[StringLength(256)]
public string UserName { get; set; }

public string PasswordHash { get; set; }

public string SecurityStamp { get; set; }

[StringLength(256)]
public string Email { get; set; }

public bool EmailConfirmed { get; set; }

public bool Is_Active { get; set; }

[Required]
[StringLength(128)]
public string Discriminator { get; set; }

public int? user_type_id { get; set; }

public bool Has_accepted_policy { get; set; }

public string PhoneNumber { get; set; }

public bool PhoneNumberConfirmed { get; set; }

public bool TwoFactorEnabled { get; set; }

public DateTime? LockoutEndDateUtc { get; set; }

public bool LockoutEnabled { get; set; }

public int AccessFailedCount { get; set; }

... other virtual properties 
and when I try to register a user I have the following exception

  
The entity type ApplicationUser is not part of the model for the current context
at this line
IdentityResult result = await UserManager.CreateAsync(user, model.Password);
My startup.Auth.cs 
UserManagerFactory = () => new UserManager<ApplicationUser>(new UserStore<ApplicationUser>());
And in my AccountController I declare my UserManager like this
public AccountController()
    : this(Startup.UserManagerFactory(), Startup.OAuthOptions.AccessTokenFormat)
{
}

public AccountController(UserManager<ApplicationUser> userManager,
    ISecureDataFormat<AuthenticationTicket> accessTokenFormat)
{
    UserManager = userManager;
    AccessTokenFormat = accessTokenFormat;
}

public UserManager<ApplicationUser> UserManager { get; private set; }
I haven't changed anything except the new properties in the AspNetUser class and it used to work well before the migration. 

There's a similar issue on CodePlex marked as fixed but they don't give the solution

Does anyone know how to fix this?

EDIT

To be sure I didn't do any mistakes when I edited my SQL database. I created another project and generated an Identity database and I changed the connection string for that database and I still have the same error.

SOLUTION

When I have edited my database I haven't noticed that in Identity 2.0.0 they changed the User_Id for UserId in AspUserClaims table. After doing that I had the same error but then I did what tschmit007 said about adding the ApplicationDbContext to the UserStore constructor and now it works. 
UserManagerFactory = () => new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));

解决方案
for me it seems to miss a context instanciation:
UserManagerFactory = () => new UserManager<ApplicationUser>(new UserStore<ApplicationUser>());
should be
UserManagerFactory = () => new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
