通过CakePHP中关联模型的条件查找3

Question

我有两个表orders和sub_orders。 他们的协会是

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

两个表分别有invoice_no和sub_invoice列orders和sub_orders。

我必须找到orders表中的记录含有相关sub_orders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' 
    ] 
    ]); 

但是这给了错误

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

Answer 1

尝试做这样的查询：

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

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