迁移到 Asp.Net Identity 2.0：未在 AspNetUsers 表中创建新列

Question

当我尝试使用 Identity 2.0 和默认的 MVC 5 应用程序注册新用户时出现以下错误：

Invalid column name 'Email'.
Invalid column name 'EmailConfirmed'.
Invalid column name 'PhoneNumber'.
Invalid column name 'PhoneNumberConfirmed'.
Invalid column name 'TwoFactorEnabled'.
Invalid column name 'LockoutEndDateUtc'.
Invalid column name 'LockoutEnabled'.
Invalid column name 'AccessFailedCount'.
(repeats 2 more times, I have a total of 4 test users in AspNetUsers table.)

我有一个小型应用程序，我刚刚从 MVC4/Identity 1.0 升级到 MVC5/Identity 2.0，所以我的 Identity 1.0 列（UserName、PasswordHash、SecurityStamp、Discriminator）正常工作。

• 我正在使用带有标准 Identity 1.0 表的远程托管 SQL2012 数据库。
• 我创建了一个“干净”的项目，注册了一个用户，它在 localDB 上运行良好。
• 我在远程数据库上成功运行了“add-migration initial”和“update-database”。
• 我最初关注的是 this official guide ，但没有生成步骤 5 中的代码。我尝试手动粘贴它并再次运行“update-database -verbose”。似乎成功完成，但仍然收到错误。

感谢任何帮助！

迁移和配置.cs 文件

internal sealed class Configuration : DbMigrationsConfiguration<FactBanker.Models.ApplicationDbContext>
{
    public Configuration()
    {
        AutomaticMigrationsEnabled = true;
    }

    protected override void Seed(FactBanker.Models.ApplicationDbContext context)
    {

    }
}

}

我的 V023 migration.cs 文件 Up() 和 Down() 方法都是空的。

public partial class V023 : DbMigration
{
    public override void Up()
    {

    }

    public override void Down()
    {

    }
}

Answer 1

您确定您的 Dbcontext 中有正确的 User 类吗？如果你想修改你的用户表，你应该这样继承：

public class ApplicationDbContext : IdentityDbContext<MyCustomUserClass>
{
    ...
}

不要放类似的东西：

public DbSet<MyCustomUserClass> Users { get; set; }

在那里，因为它已经发生在基类中。

Answer 2

原因是您已升级到 Microsoft.AspNet.Identity.EntityFramework 2.0.0.0 并且更改了用户上下文。

修复要么生成一个新的 db（设置一个新的连接字符串 mdf 文件）或更改 sql 表。

我遇到了同样的问题。根据 Dan Gershony 所说，我只是卸载了 Microsoft.AspNet.Identity.EntityFramework 2.0.0.0 并安装了旧版本，如 Microsoft.AspNet.Identity.EntityFramework -Version 1.0.0。这解决了我的问题。

Answer 4

我遇到了同样的问题。我使用了这个手动迁移，还没有遇到任何其他问题。

public override void Up()
{
    RenameColumn(table: "dbo.AspNetUserClaims", name: "User_Id", newName: "UserId");
    RenameIndex(table: "dbo.AspNetUserClaims", name: "IX_User_Id", newName: "IX_UserId");
    DropPrimaryKey("dbo.AspNetUserLogins");
    AddColumn("dbo.AspNetUsers", "Email", c => c.String(maxLength: 256));
    AddColumn("dbo.AspNetUsers", "EmailConfirmed", c => c.Boolean(nullable: false));
    AddColumn("dbo.AspNetUsers", "PhoneNumber", c => c.String()); 
    AddColumn("dbo.AspNetUsers", "PhoneNumberConfirmed", c => c.Boolean(nullable: false));
    AddColumn("dbo.AspNetUsers", "TwoFactorEnabled", c => c.Boolean(nullable: false));
    AddColumn("dbo.AspNetUsers", "LockoutEndDateUtc", c => c.DateTime());
    AddColumn("dbo.AspNetUsers", "LockoutEnabled", c => c.Boolean(nullable: false));
    AddColumn("dbo.AspNetUsers", "AccessFailedCount", c => c.Int(nullable: false));
    AlterColumn("dbo.AspNetUsers", "UserName", c => c.String(nullable: false, maxLength: 256));
    AlterColumn("dbo.AspNetUsers", "FirstName", c => c.String(nullable: false));
    AlterColumn("dbo.AspNetUsers", "LastName", c => c.String(nullable: false));
    AddColumn("dbo.AspNetUsers", "CreatedDateTime", c => c.DateTime(nullable: false));
    AlterColumn("dbo.AspNetRoles", "Name", c => c.String(nullable: false, maxLength: 256));
    AddPrimaryKey("dbo.AspNetUserLogins", new[] { "LoginProvider", "ProviderKey", "UserId" });
    CreateIndex("dbo.AspNetUsers", "UserName", unique: true, name: "UserNameIndex");
    CreateIndex("dbo.AspNetRoles", "Name", unique: true, name: "RoleNameIndex");
    DropColumn("dbo.AspNetUsers", "Discriminator");
}

尝试了 user1502551 提出的解决方案，但它给了我一些问题，并且没有包含 Down() 方法。我遇到的问题是，Identity 1.0 中默认情况下不存在被更改的索引，并且有几个 2.0/2.1 没有预料到的额外列（即名字和姓氏字段）。完整的 Up() 和 Down() 在这里：

public override void Up()
    {
        RenameColumn(table: "dbo.AspNetUserClaims", name: "User_Id", newName: "UserId");
        AddColumn("dbo.AspNetUsers", "Email", c => c.String());
        AddColumn("dbo.AspNetUsers", "EmailConfirmed", c => c.Boolean(nullable: false));
        AddColumn("dbo.AspNetUsers", "PhoneNumber", c => c.String());
        AddColumn("dbo.AspNetUsers", "PhoneNumberConfirmed", c => c.Boolean(nullable: false));
        AddColumn("dbo.AspNetUsers", "TwoFactorEnabled", c => c.Boolean(nullable: false));
        AddColumn("dbo.AspNetUsers", "LockoutEndDateUtc", c => c.DateTime());
        AddColumn("dbo.AspNetUsers", "LockoutEnabled", c => c.Boolean(nullable: false));
        AddColumn("dbo.AspNetUsers", "AccessFailedCount", c => c.Int(nullable: false));
        AlterColumn("dbo.AspNetUsers", "UserName", c => c.String(nullable: false));
        DropColumn("dbo.AspNetUsers", "Discriminator");
    }

    public override void Down()
    {
        AddColumn("dbo.AspNetUsers", "Discriminator", c => c.String(nullable: false, maxLength: 128));
        AlterColumn("dbo.AspNetUsers", "UserName", c => c.String(nullable: true));
        DropColumn("dbo.AspNetUsers", "AccessFailedCount");
        DropColumn("dbo.AspNetUsers", "LockoutEnabled");
        DropColumn("dbo.AspNetUsers", "LockoutEndDateUtc");
        DropColumn("dbo.AspNetUsers", "TwoFactorEnabled");
        DropColumn("dbo.AspNetUsers", "PhoneNumberConfirmed");
        DropColumn("dbo.AspNetUsers", "PhoneNumber");
        DropColumn("dbo.AspNetUsers", "EmailConfirmed");
        DropColumn("dbo.AspNetUsers", "Email");
        RenameColumn(table: "dbo.AspNetUserClaims", name: "UserId", newName: "User_Id");
    }

你必须修改所有在2.0版本中更新的实体，例如：

public partial class AspNetUser
{    
    public AspNetUser()
    {
        AspNetUserClaims = new HashSet<AspNetUserClaim>();
        AspNetUserLogins = new HashSet<AspNetUserLogin>();
        AspNetRoles = new HashSet<AspNetRole>();
    }

    public string Id { get; set; }

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

    public string PasswordHash { get; set; }

    public string SecurityStamp { get; set; }

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

    public bool EmailConfirmed { 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; }

    public int UserId { get; set; }

    public virtual ICollection<AspNetUserClaim> AspNetUserClaims { get; set; }

    public virtual ICollection<AspNetUserLogin> AspNetUserLogins { get; set; }

    public virtual User User { get; set; }

    public virtual ICollection<AspNetRole> AspNetRoles { get; set; }
}

public partial class AspNetUserClaim
{
    [Key]
    [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }

    public string ClaimType { get; set; }

    public string ClaimValue { get; set; }

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

    public virtual AspNetUser AspNetUser { get; set; }
}

您还需要修改在您的 dbcontext 的 OnModelCreating 方法中更改的实体的映射，之后您可以添加您的迁移

Answer 7

我遇到了同样的错误。我所做的只是在 AspNetUser 中手动添加 LockoutEndDateUtc 列
