我最近使用https://github.com/dereuromark/upgrade 将我的 1.3-app 升级到 2.4
但是现在$this->Model->find() 的某些用法不起作用。尤其是与关联模型/表的连接。
导致“where 子句中的未知列 'Bill.customer_id'”。

我的设置：

表格和关联： http: //i.stack.imgur.com/bjOIz.png （图片）

型号：

App::uses('AppModel', 'Model');
class Customer extends AppModel {
public $actsAs = array('Logable', 'Containable');
public $hasMany = array(
    'Bill' => array(
        'className' => 'Bill',
        'foreignKey' => 'customer_id',
        'dependent' => false,
        'conditions' => '',
        'fields' => '',
        'order' => '',
        'limit' => '',
        'offset' => '',
        'exclusive' => '',
        'finderQuery' => '',
        'counterQuery' => ''
    )...

在 1.3 中，连接正在工作。在 2.4 中只有一维的 sql 查询。

任何想法？

$billsStages = $this->Customer->Bill->BillsStage->find('all', array(
  'conditions' => array(
      'Bill.customer_id' => $this->Customer->id,
      'Stage.id' => array_keys($vk_stages)
    ),
  'order' => 'BillsStage.created DESC'
));

尝试加入（从文档中取出的示例）

$options['joins'] = array(
    array('table' => 'bills',
        'alias' => 'Bill',
        'type' => 'LEFT',
        'conditions' => array(
            'Bill.customer_id' => $this->Customer->id,
        )
    ),
    array('table' => 'stages',
        'alias' => 'Stage',
        'type' => 'LEFT',
        'conditions' => array(
            'Stage.id' => array_keys($vk_stages)
        )
    )
);

$options['conditions'] = array();

$items= $this->Customer->Bill->BillsStage->find('all', $options);

（根据您的情况调整）。

根据这个答案，contain辅助模型上的 for 条件是不可能的，因为contain会进行不同的查询。因此，如果您想在辅助模型上应用条件，请使用连接，或者在您的模型中创建一个简单的函数，该函数执行两个单独的查询并创建一个宏数组，如果您想使用返回混合结果的contain.
