將管理員用戶播種到資料庫OnModelCreating

應用程式角色.cs：

  public class ApplicationRole : IdentityRole<Guid>
  {
    public virtual ICollection<ApplicationUserRole> UserRoles { get; set; }
  }

應用程式背景關系：

  public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, Guid, IdentityUserClaim<Guid>,
  ApplicationUserRole, IdentityUserLogin<Guid>,
  IdentityRoleClaim<Guid>, IdentityUserToken<Guid>>
  {
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {

    }
        ...
    }

如果不運行一些代碼，我真的不能說問題出在哪里，但我可以向您展示我的實作，也許它會響起。這是我的版本：

public class SessionDbContext : IdentityDbContext<MachineUserIdentity, IdentityRole<Guid>, Guid>
{
    ...
    
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        // Default users
        modelBuilder.ApplyConfiguration(new IdentityUserModelConfig());
        // Default roles
        modelBuilder.ApplyConfiguration(new IdentityRoleModelConfig());
        // User claims
        modelBuilder.ApplyConfiguration(new IdentityUserClaimsModelConfig());
        // Role claims
        modelBuilder.ApplyConfiguration(new IdentityRoleClaimsModelConfig());
        // User roles assignment
        modelBuilder.ApplyConfiguration(new IdentityUserRoleModelConfig());
    }
}

我已經創建了一個單獨的 Foreach 資料表，IEntityTypeConfiguration但它不應該改變任何東西。以下是用戶、角色和用戶角色的實作：

IEntityTypeConfiguration<MachineUserIdentity>與MachineUserIdentity繼承IdentityUser<Guid>：

public void Configure(EntityTypeBuilder<MachineUserIdentity> builder)
    {
        // Seed default roles
        builder.HasData(SeedHelpers.DefaultUsers);
    }

IEntityTypeConfiguration<IdentityRole<Guid>>：

public void Configure(EntityTypeBuilder<IdentityRole<Guid>> builder)
    {
        // Seed default roles
        builder.HasData(SeedHelpers.GenerateDefaultRoles());
    }

IEntityTypeConfiguration<IdentityUserRole<Guid>>：

public void Configure(EntityTypeBuilder<IdentityUserRole<Guid>> builder)
    {
        // Seed default roles
        builder.HasData(SeedHelpers.GenerateUserRolesAssignment());
    }

與您正在做的事情非常相似。最后，我有一個播種助手類，我在其中定義如下資料：

internal const string GUID_USER_OPERATOR = "491a282c-3af1-4d45-b6a1-6014b8195744";
internal const string GUID_USER_SERVICE = "337acfd6-fde7-4d5c-9c0b-08fed843a3ed";

internal const string GUID_ROLE_OPERATOR = "d80a2a14-78a7-4e9d-b228-1cd259bd8cd3";
internal const string GUID_ROLE_SERVICE = "69605900-4fb1-4558-a9d4-6bdf3f184819";

// Password do not belong here, move them to a key vault
// This is just for demo purposes
internal const string ID_DEFAULT_ACCOUNT = "ADMIN";
internal const string ID_DEFAULT_PASSWORD = "ADMIN";

internal const string ID_SERVICE_ACCOUNT = "SERVICE";
internal const string ID_SERVICE_PASSWORD = "SERVICE1234";

internal static List<MachineUserIdentity> DefaultUsers = new()
{
    new()
    {
        Id = Guid.Parse(GUID_USER_OPERATOR),
        UserName = ID_DEFAULT_ACCOUNT,
        NormalizedUserName = ID_DEFAULT_ACCOUNT,
        Role = MachineRoleId.Operator.ToString(),
        PasswordHash = hasher.HashPassword(null, ID_DEFAULT_PASSWORD),
    },
    new()
    {
        Id = Guid.Parse(GUID_USER_SERVICE),
        UserName = ID_SERVICE_ACCOUNT,
        NormalizedUserName = ID_SERVICE_ACCOUNT,
        Role = MachineRoleId.Service.ToString(),
        PasswordHash = hasher.HashPassword(null, ID_SERVICE_PASSWORD),
    }
};

internal static IdentityRole<Guid>[] GenerateDefaultRoles()
{
    return new[]
    {
        new(MachineRoleId.Operator.ToString())
        {
            Id = Guid.Parse(GUID_ROLE_OPERATOR),
            Name = MachineRoleId.Operator.ToString(),
            NormalizedName = MachineRoleId.Operator.ToString().ToUpper(),
        },
        new IdentityRole<Guid>
        {
            Id = Guid.Parse(GUID_ROLE_SERVICE),
            Name = MachineRoleId.Service.ToString(),
            NormalizedName = MachineRoleId.Service.ToString().ToUpper(),
        }
    };
}

internal static IdentityUserRole<Guid>[] GenerateUserRolesAssignment()
{
    return new[]
    {
        new()
        {
            RoleId = Guid.Parse(GUID_ROLE_OPERATOR),
            UserId = Guid.Parse(GUID_USER_OPERATOR),
        },
        new IdentityUserRole<Guid>
        {
            RoleId = Guid.Parse(GUID_ROLE_SERVICE),
            UserId = Guid.Parse(GUID_USER_SERVICE),
        }
    };
}

我想除了我使用硬編碼的 GUID（我自己選擇在所有目標機器上使用相同的識別符號）并且我沒有像你一樣明確宣告 UserRole 表的鍵之外，沒有太大區別。

希望這可以幫助 ;）

不確定這是否能解決您的問題，但我注意到您正在為 ADMIN_ID 分配新的 GUID 值，然后基本上將相同的值傳遞給 ROLE_ID。為 ROLE_ID 分配一個新的唯一值，然后重試種子。
