laravel 5.1 MorphToMany＆amp; MorphBy​​Many包含自定义字段

Question

我在表中有自定义字段，并希望MorpTohmany与其他表。如何使用自定义字段。

在以下型号（ salepurchase ） request_to 是供应商型号外键，其中 salepurchase_type < / strong>和 salepurchase_id 这些将包含其他模型关系，如仓库，商店等

SalePurchase 型号

+----+------------+-------------------+-----------------+-------------+
| id | request_to | salepurchase_type | salepurchase_id | total_items |
+----+------------+-------------------+-----------------+-------------+
|  1 |          1 | Warehouse         |               1 |          10 |
|  2 |          1 | Warehouse         |               1 |          10 |
|  3 |          1 | Warehouse         |               1 |          11 |
|  4 |          1 | Shop              |               7 |          15 |
|  5 |          1 | Shop              |               5 |          19 |
+----+------------+-------------------+-----------------+-------------+

仓库型号

+----+-------------+
| id | name        |
+----+-------------+
|  1 | warehosue 1 |
|  2 | warehosue 2 |

购物型号

+----+-------------+
| id | name        |
+----+-------------+
|  5 | Shop 1      |

供应商型号

| id | qualified_person         |
+----+--------------------------+

Answer 1

在您的模型中，只需添加关系：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class SalePurchase extends Model
{
    /**
     * Get all of the owning salepurchase models.
     */
    public function salepurchase()
    {
        return $this->morphTo();
    }

   public function supplier()
   {
     return $this->belongsTo('App\Supplier','request_to','id');
   }
}

然后在其他模特中：

class Shop extends Model
{
    /**
     * Get all of the Shop's purchases.
     */
    public function salepurchases()
    {
        return $this->morphMany('App\SalePurchase', 'salepurchase');
    }
}

在您的供应商模型中：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Supplier extends Model
{
    public function salepurchases()
    {
      return $this->hasMany('App\SalePurchases');
    }
}

我认为这里不需要MorphedByMany。由于SalePurchases表保存了Morphed字段。
