Question

大家好我正试图继承标准的AspNet表。

我的目的是使用Guid作为主键并扩展基本的AspNetUser 有一些属性。此外，我想重命名表名。

现在就像：

public class User : IdentityUser<Guid, UserLogin, UserRole, UserClaim>
{

    public User() { }

    public User(string userName)
    {
        this.UserName = userName;
    }


    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<User, Guid> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;
    }
 }

我的DbContext看起来像这样：

 public class CustomDBContext : IdentityDbContext<User, Role, Guid, UserLogin, UserRole, UserClaim>
{

     public static CustomDBContext Create()
    {
        return new CustomDBContext();
    }

     protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {

        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<IdentityRole<Guid, UserRole>>().ToTable("Roles");
        modelBuilder.Entity<IdentityUserLogin<Guid>>().ToTable("UserLogins");
        modelBuilder.Entity<IdentityUserClaim<Guid>>().ToTable("UserClaims");
        modelBuilder.Entity<IdentityUserRole<Guid>>().ToTable("UserRoles");
        modelBuilder.Entity<IdentityUser<Guid, UserLogin, UserRole, UserClaim>>().ToTable("Users");

    }
}

不幸的是，Iam尝试生成我的迁移。我收到了这个错误：

类型＆＃39; Microsoft.AspNet.Identity.EntityFramework.IdentityRole`2 [System.Guid，Easy1WebAPIData.Models.UserRole]＆＃39;没有映射。使用Ignore方法或NotMappedAttribute数据批注检查未明确排除类型。验证类型是否已定义为类，不是原始类型还是通用类型，并且不从EntityObject继承。

有什么想法吗？最好的问候！

我认为您只需要在OnModelCreating方法中映射扩展模型。我在我的一个项目上做了以下工作，它在迁移方面做得很好。

public class ApplicationUser : IdentityUser<Guid, CustomUserLogin, CustomUserRole, CustomUserClaim> { }
public class CustomUserRole : IdentityUserRole<Guid> { }
public class CustomUserClaim : IdentityUserClaim<Guid> { }
public class CustomUserLogin : IdentityUserLogin<Guid> { }
public class CustomRole : IdentityRole<Guid, CustomUserRole> { }

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, CustomRole, Guid, CustomUserLogin, CustomUserRole, CustomUserClaim> 
{
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.Entity<ApplicationUser>().ToTable("Users");
        modelBuilder.Entity<CustomRole>().ToTable("Roles");
        modelBuilder.Entity<CustomUserRole>().ToTable("UserRoles");
        modelBuilder.Entity<CustomUserLogin>().ToTable("UserLogins");
        modelBuilder.Entity<CustomUserClaim>().ToTable("UserClaims");
    }
}

另外，如果您使用Guid的密钥，那么在对象的构造函数中设置Id是很常见的。

public class ApplicationUser : IdentityUser<Guid, CustomUserLogin, CustomUserRole, CustomUserClaim>
{
    public ApplicationUser()
    {
        public ApplicationUser()
        {
            Id = Guid.NewGuid();
        }
    }
}

最后它奏效了！致@Phil Thomas

        modelBuilder.Entity<User>().ToTable("User").Property(p => p.Id).HasColumnName("UserID");
        modelBuilder.Entity<User>().Property(p => p.Email).HasColumnName("EmailAddress");

        modelBuilder.Entity<UserRole>().HasKey(r => new { r.RoleId, r.UserId });
        modelBuilder.Entity<UserRole>().ToTable("UserRole");
        modelBuilder.Entity<UserRole>().Property(r => r.UserId).HasColumnName("UserID");
        modelBuilder.Entity<UserRole>().Property(r => r.RoleId).HasColumnName("RoleID");

        modelBuilder.Entity<UserLogin>().ToTable("UserLogin");
        modelBuilder.Entity<UserLogin>().Property(r => r.UserId).HasColumnName("UserID");

        modelBuilder.Entity<UserClaim>().ToTable("UserClaim");
        modelBuilder.Entity<UserClaim>().Property(r => r.Id).HasColumnName("UserClaimID");

        modelBuilder.Entity<Role>().HasKey<Guid>(r => r.Id);
        modelBuilder.Entity<Role>().ToTable("Role");
        modelBuilder.Entity<Role>().Property(r => r.Id).HasColumnName("RoleID");
