我有两个模型电子商务订单和药品

class EcommerceOrders extends Model
{
    use HasFactory;

    protected $table = 'ecommerce_orders';

    protected $fillable = [
        'user_id',
        'manager_id',
        'first_name',
        'last_name',
        'phone_number',
        'email',
        'address',
        'city',
        'zip_code',
        'other_info',
        'products',
        'total_price',
        'qr_code',
        'status',
        'assigned_to',
        'save_client_info',
    ];

class Medicines extends Model
{
    use HasFactory;
    use Notifiable;
    use SoftDeletes;

    /**
     * The attributes that are mass assignable.
     *
     * @var string[]
     */

    protected $table = 'medicines';
  
    protected $fillable = [
        'name',
        'subcategory_id',
        'group',
        'unity',
        'description',
        'price',
        'discount',
        'type',
        'photo_path',
        'slug'
    ];

在EcommerceOrders模型中，products字段保存客户购买的商品的信息，我尝试做的是获取这些产品的数据。
电子商务订单

public function items()
    {
        return $this->hasMany(Medicines::class,'id');
    }

药品

public function ecomOrders()
 {
        return $this->belongsTo(EcommerceOrders::class);
 }

但是，当我尝试获取数据时，它只显示产品中第一个项目的信息

EcommerceOrders::where('id',3)->with('items')->get()

Illuminate\Database\Eloquent\Collection {#3313
     all: [
       App\Models\EcommerceOrders {#3298
