CakePHP 3通过关联模型进行排序,具有一个关系 订单有一个子订单 子订单属于订单
我需要按子订单中的字段对订单进行排序,但在Cake 3.x中,按虚拟字段排序似乎已被删除 在CakePHP 3通过关联模型进行排序,具有一个关系 订单有一个子订单 子订单属于订单,cakephp,pagination,cakephp-3.x,Cakephp,Pagination,Cakephp 3.x,我需要按子订单中的字段对订单进行排序,但在Cake 3.x中,按虚拟字段排序似乎已被删除 在OrdersTable.php中,我有 $this->hasOne('Suborder', [ 'className' => 'Suborders', 'foreignKey' => 'order_id', 'strategy' => 'select', 'conditions' => function

。如何让Cake在初始查询中包含子订单以进行排序和分页
编辑:
$collection = $this->Orders->find()
->contain([
'Clients',
'CurrentAssignment.Users',
'Workflows.OrderStatuses.Category',
'Workflows.OrderStatuses.Departments' => function ($q) use ($uID) {
return $this->Departments->find()->matching('Users', function ($q) use ($uID) {
return $q->where(['Users.id' => $uID]);
});
},
'ClientProducts.ProductTypes',
'Reviews' => function ($q) {
return $q->where(['review_type_id is not' => 6]);
},
'Reviews.ReviewTypes',
'PublicNotes',
'ActiveReview',
'Suborder',
'Suborder.SuborderTypes',
'Suborders.SuborderTypes',
]);
并且,
$collection
被修改为150行where,或where,并基于许多条件进行连接。您已将关联配置为使用选择
策略,该策略将使用单独的查询来检索数据(),因此您无法在用于分页的主查询中引用它
因此,如果要对其进行排序,则必须使用默认的join
策略

$collection
到底是什么!虽然原因对于习惯使用CakePHP的人来说是显而易见的,但它仍然可能取决于$collection
到底是什么!
