【问题描述】:
产品名称/标题表列与代码中使用的 My eloquent 关系不匹配
@if(is_null($order->orderid)) 没有产品 @else {{$order->products- >title}} @endif
<tbody>
@foreach($orders as $order)
<tr class="">
@endif
<td>{{$order->customer_email}}</td>
<td>{{$order->customer_name}}</td>
<td>{{array_sum($order->quantities)}}</td>
<td>{{$order->customer_city}}</td>
<td>@if(is_null($order->orderid)) No Product @else {{$order->products->title}} @endif</td>
<td>{{$order->method}}</td>
</tr>
@endforeach
</tbody>
这是我的产品型号和![数据库结构]https://i.postimg.cc/fT4t8xFv/products.png [![产品型号截图][1]][1]
namespace App;
use Illuminate\Database\Eloquent\Model;
class Product extends Model
{

public static $withoutAppends = false;
public function vendor()
{
return $this->belongsTo('App\Vendors', 'vendorid', 'id');
}
public function order()
{
return $this->belongsTo('App\Order', 'products');
}
}
这是我的订单模型和![数据库结构]https://i.postimg.cc/yN5YkKCT/orders.png [![订单模型截图][2]][2]
namespace App;
use Illuminate\Database\Eloquent\Model;
class Order extends Model
{
protected $fillable = [
'customerid', 'products', 'quantities', 'method', 'shipping', 'pickup_location', 'pay_amount',
'txnid', 'charge_id', 'order_number', 'payment_status', 'customer_email', 'customer_name',
'customer_phone', 'customer_address', 'customer_city', 'customer_zip', 'shipping_name',
'shipping_email', 'shipping_phone', 'shipping_address', 'shipping_city', 'shipping_zip',
'order_note', 'booking_date', 'status'
];
public $timestamps = false;
public static $withoutAppends = false;
public function products()
{
return $this->hasMany('App\Product', 'orderid', 'id');
}
}
试图获取非对象的属性
【问题讨论】:
-
将
orders表的外键添加到products表中。 -
你不能直接访问
$order->products->title它在hasMany关系中。public function order() { return $this->belongsTo('App\Order', 'here should be foreign key not primary key', 'id'); }或者在关系中您提到与许多产品相关的订单,但在产品表的屏幕截图中没有产品 ID。我认为你误解了关系。 -
你搞砸了关系。如果您想使用 hasMany 关系,请使用数据透视表或为订单中的每个产品创建一个新行并使用 belongsTo 关系。
-
已经添加了order_id外键
