在 CakePHP 3 中按条件查找关联模型

Question

我有两张桌子orders 和sub_orders。 他们的关联是

$orders->hasMany('SubOrders', [
   'foreignKey' => 'order_id'
]);

两个表在orders 和sub_orders 中分别有invoice_no 和sub_invoice 列。

我必须从包含关联sub_orders 的orders 表中查找记录，其中$trackingId 将匹配Orders.invoice_no 或SubOrders.sub_invoice

$findOrder = $this->Orders->find('all', [
    'conditions' => [
      'OR' => [
         'Orders.invoice_no' => $trackingId,
         'SubOrders.sub_invoice' => $trackingId
       ]
     ],
     'contain' => [
        'SubOrders'
     ]
  ]);

但这会出错

Column not found: 1054 Unknown column 'SubOrders.sub_invoice' in 'where clause'

Answer 1

尝试这样查询：

$findOrder = $this->Orders->find()
->where(['Orders.invoice_no' => $trackingId])
->contain(['SubOrders' => function ($q) use ($trackingId) {
   return $q

        ->where(['SubOrders.sub_invoice' => $trackingId]);
}
]);
