【问题描述】：

我有两个模型 EcommerceOrders 和 Medicines

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，产品字段包含有关客户购买的商品的信息我想做的是获取有关这些产品的数据。这就是我在每个模型中创建关系的方式

电商订单

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

药物

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

但是，当我尝试获取数据时，它仅显示有关产品中第一项的信息

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

Illuminate\Database\Eloquent\Collection {#3313
     all: [
       App\Models\EcommerceOrders {#3298
         id: 3,
         user_id: 2,
         manager_id: 3,
         first_name: "test",
         last_name: "test1",
         phone_number: "3550123456",
         email: "asd@test.com",
         address: "addsss",
         city: "qwerr",
         zip_code: "625",
         other_info: null,
         products: "{"2":1,"3":1}", //id: quantity
         total_price: "8309,00",
         qr_code: "2416718593exKrLbcNEpVm3nYI6S31652402",
         status: "ordered",
         assigned_to: null,
         save_client_info: 1,
         created_at: "2022-11-22 17:35:32",
         updated_at: "2022-11-22 17:35:32",
         items: Illuminate\Database\Eloquent\Collection {#3315
           all: [
             App\Models\Medicines {#3327
               id: 3,
               group: 11,
               name: "quisquam",
               subcategory_id: 8,
               unity: "499mg",
               description: "Quo autem aut quibusdam dolorem aut sit.",
               price: 6935.0,
               discount: 9.0,
               type: 0,
               photo_path: "https://via.placeholder.com/640x480.png/009900?text=laudantium",
               slug: "quisquam",
               created_at: "2022-11-21 11:39:29",
               updated_at: "2022-11-21 11:39:29",
               deleted_at: null,
             },
           ],
         },
       },
     ],
   }

【问题讨论】：

您可以编辑问题并添加查询吗？
这是我的查询 EcommerceOrders::where('user_id', auth()->id)->with('items')->get()

标签： laravel eloquent eloquent-relationship

【解决方案1】：

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

此查询仅获取 id 为 3 的行并且因为它是和递增 ID，所以只有 1 项将是 ID:3
