Question

我最近使用https://github.com/dereuromark/upgrade将我的1.3-app升级到2.4 但现在 $ this-＆gt;模型 - ＆gt; find（）的一些用法不起作用。特别是与相关模型/表格的连接。
导致where子句中的“未知列”Bill.customer_id'。

我的设置：

模型：

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' => ''
    )...

class Bill extends AppModel {
public $actsAs = array('Containable', 'Logable', 'Lockable');

public $belongsTo = array(

        'foreignKey' => 'customer_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    )...

public $hasAndBelongsToMany = array(
    'Stage' => array(
        'className' => 'Stage',
        'joinTable' => 'bills_stages',
        'foreignKey' => 'bill_id',
        'associationForeignKey' => 'stage_id',

        'associationForeignKey' => 'bill_id',

        'finderQuery' => '',
        'deleteQuery' => '',
        'insertQuery' => ''
    )...

在1.3中，连接工作正常。在2.4中只有1维sql查询。

有什么想法吗？

- 修改 -

$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'
));

Answer 1

尝试加入（例如从docs中取出）

$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);

（根据你的情况调整）。

根据this answer，无法在辅助模型上使用contain条件，因为contain会生成不同的查询。因此，如果要在辅助模型上应用条件，或者在模型中创建一个执行两个单独查询的简单函数，则创建一个宏数组，如果要使用contain，则返回混合结果。

升级1.3后 - > 2.4：find（）不加入关联模型
