我在过滤记录时遇到问题，我不希望任何记录都有空模型。
$this->paginate = array('fields' =>
array('DISTINCT Joborder.id',
'Joborder.job_type',
'Joborder.payment_status',
'Joborder.estimate_id',
'Joborder.quantity',
'Joborder.date_created'
),
'contain' => array(
'Workorder.id',
'Workorder.joborder_id',
'Joborderpart.id',
'Joborderpart.binding',
'Orderstatus.id',
'Estimate' => array(
'Client' => array(
'fields' => array(
'Client.company_name'
)
)
),
'Orderstatus' => array(
'fields' => array('Orderstatus.id'),
'order' => array(
'Orderstatus.id DESC'
),
'conditions' => array(
'Orderstatus.Orderstatustype_id LIKE' => 5
),
'Orderstatustype' => array(
'fields' => array(
'Orderstatustype.id',
'Orderstatustype.orderstatus'
)
),
'limit' => 1
)
)
);
我已经在Orderstatus表中检查了一个条件，用于选择发货的ordertatustype_id LIKE 5。
我只需要发送记录，但它会提取所有记录，如下所示

这是Containable的预期行为。如果给定模型没有记录，则返回一个空数组。
摆脱它们的唯一方法是遍历生成的数组并过滤掉空子。 This article提出了一个涉及afterFind()的解决方案。

可以通过包含连接以及包含和检查空值来从分页中删除空包含结果。
例如： -
$this->paginate = array(
'fields' => array(
'DISTINCT Order.id',
'Order.*'
),
'conditions' => array(
'OrderItem.id IS NOT NULL'
),
'joins' => array(
array(
'table' => 'order_items',
'alias' => 'OrderItem',
'type' => 'LEFT',
'conditions' => array('Order.id = OrderItem.order_id')
)
),
'contain' => array(
'OrderItem'
)
)
这将确保只返回包含订单商品的订单。
