将ASP.NET身份与核心域模型分离 – 洋葱架构

在此示例中,作者使用适配器模式来分离核心标识类(IdentityUser,IdentityRole …),并在Core层中提供类似它们的类.

现在这个示例项目中的问题是Domain模型(Product,Images)没有与模仿Identity模型的虚拟类(AppUser,ApplicationRole,AppliationUserRoles,…)链接.

然后我修改了代码以添加对AppUser的引用

public sealed class Image : BaseEntity
{
    public Image()
    {
        Products = new HashSet<Product>();
    }

    public string Path { get; set; }

    public AppUser AppUser { get; set; } // The  Added Reference ...

    public ICollection<Product> Products { get; set; }
}

如果我将“AppUser”导航属性放在“Image”类中,则创建的数据库将具有除标识框架的默认FIVE表之外的四个新表.

我需要将这些表合并为默认表.
怎么样 ？

编辑：

这是驻留在数据层中的身份模型(我无法从核心引用).

public class ApplicationIdentityUser :
    IdentityUser<int,ApplicationIdentityUserLogin,ApplicationIdentityUserRole,ApplicationIdentityUserClaim>,IDomainUser {

    public ApplicationIdentityUser()
        : base() {
        Images = new HashSet<Image>();
    }

    public string Name { get; set; }
    public virtual ICollection<Image> Images { get; set; }
}


public class ApplicationIdentityRole : IdentityRole<int,ApplicationIdentityUserRole>
{
    public ApplicationIdentityRole(){}

    public ApplicationIdentityRole(string name){Name = name;}
}

public class ApplicationIdentityUserRole : IdentityUserRole<int> {}

public class ApplicationIdentityUserClaim : IdentityUserClaim<int>{}

public class ApplicationIdentityUserLogin : IdentityUserLogin<int>{}

这也是我在OnModelCreating方法中的模型构建器：

modelBuilder.Entity<Image>()
            .Property(e => e.Id)
            .HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
        modelBuilder.Entity<Image>()
            .HasMany(e => e.Products)
            .WithRequired(e => e.Image)
            .WillCascadeOnDelete(false);
        modelBuilder.Entity<ApplicationIdentityUser>()
             .Property(e => e.Id)
             .HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
        modelBuilder.Entity<ApplicationIdentityRole>()
            .Property(e => e.Id)
            .HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
        modelBuilder.Entity<ApplicationIdentityUserClaim>()
             .Property(e => e.Id)
             .HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
