Question

我正在尝试为身份验证创建自定义表，但无论我多次尝试重新创建Identity表，我都会收到此错误：

实体类型＆＃39; BBRoleType＆＃39;和＆＃39; UserRoleType＆＃39;不能共享表＆＃39; UserRoleTypes＆＃39;因为它们不在同一类型层次结构中，或者没有有效的一对一外键关系，并且它们之间具有匹配的主键。

这是我在数据库中的用户表：

并导出为SQL：

创建表后，我为数据库添加了ADO.NET数据实体模型。

我创建了这些类来映射到自定义Identity类：

public class BBUserLogin : IdentityUserLogin<Guid> { }
public class BBUserRole : IdentityUserRole<Guid> { }

public class BBRoleType : IdentityRole<Guid,BBUserRole> { }
public class BBUserClaim : IdentityUserClaim<Guid> { }

public class BBUser : IdentityUser<Guid, BBUserLogin, BBUserRole, BBUserClaim>
{
    public DateTime CreateDate { get; set; }
    public DateTime LastOnlineDate { get; set; }
    public DateTime? BirthDate { get; set; }
    public string FacebookAccessToken { get; set; }
    public string FacebookName { get; set; }
    public string FacebookId { get; set; }

    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<BBUser, Guid> manager)
    { 
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        userIdentity.AddClaim(new Claim(TCCustomClaimTypes.FirstName, this.FacebookName.SubstringUpToFirst(' ')));
        return userIdentity;
    }
}

然后设置我的DbContext：

public class ApplicationDbContext : IdentityDbContext<BBUser, BBRoleType, Guid, BBUserLogin, BBUserRole, BBUserClaim>
{
    public ApplicationDbContext() : base("MyIdentityConnection")
    {

    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.HasDefaultSchema("dbo");

        modelBuilder.Entity<BBUser>().ToTable("User");
        modelBuilder.Entity<BBUserClaim>().ToTable("UserClaim");
        modelBuilder.Entity<BBUserLogin>().ToTable("UserLogin");
        modelBuilder.Entity<BBUserRole>().ToTable("UserRole");
        modelBuilder.Entity<BBRoleType>().ToTable("UserRoleType");

        modelBuilder.Entity<BBUser>().Property(x => x.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
        modelBuilder.Entity<BBUserClaim>().Property(x => x.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
        modelBuilder.Entity<BBRoleType>().Property(x => x.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
    }

不是我认为我很重要，但我在{I}尽可能地使用Guid / [uniqueidentifier]（使用通用TKey的地方）。 IdentityUserClaim不允许更改Id类型，因此我使用bigint。不是我认为这很重要： - ）

我一直在用这个问题把头撞到墙上，但是我无法弄清楚我做错了什么。

Answer 1

在我看来，密钥名称Id，Id，UserId和RoleId需要具有正确的命名。你可以更改密钥＆＃39; Id＆＃39;到UserId＆＃39;关于用户＆＃39;表？删除UserClaim表上的Id键。改变＆＃39; Id＆＃39;在UserRoleType表上的RoleId。

我认为这会解决您的问题。
