看看这里

              {
                    "id_peserta": 1,
                    "nama_peserta": "Zainul",
                    "tanggal_lahir": "1999-08-12",
                    "umur": 20,
                    "id_users_role": 3,
                    "organisasi": "UGM",
                    "foto_peserta": "/files/2652343.jpg",
                    "created_at": "2020-01-02 16:16:33",
                    "updated_at": "2020-01-02 16:16:33"
                }

该脚本应显示在id_users_role：3上，因为它具有外键id_users_role：3，但是在我的响应中它显示在id_users：1上，那么雄辩的话怎么了？

我也有外键

Schema::table('users_role', function (Blueprint $table) {
            $table->foreign('id_users')->references('id_users')->on('users')->onDelete('cascade');
            $table->foreign('id_role')->references('id_role')->on('role')->onDelete('cascade');
        });

Schema::table('peserta', function (Blueprint $table) {
            $table->foreign('id_users_role')->references('id_users_role')->on('users_role')->onDelete('cascade');
        });

这是我的控制器`

public function index(){
        $peserta = Users::with(['users_role', 'user_role.peserta'])->get();
        return response()->json(['Peserta', $peserta]);

`

我想要这样的结果，因为id_users_roles是peserta上的外键
