关联来自不同数据库的表 cakephp 3.0

Question

我有两个数据库，名称分别为 default 和 default_history。并且 tables 名称为 users，默认数据库下为 wafer_detail_history，default_history 数据库下为 order_history。想要将 Users table 与 OrderHistory table.

相关联

订单历史表：-

public function initialize(array $config)
{
    parent::initialize($config);

    $this->setTable('order_history');
    $this->setDisplayField('id');
    $this->setPrimaryKey('id');

    $this->addBehavior('Timestamp');

    $this->hasMany('WaferDetailHistory', [
        'foreignKey' => 'order_id'
    ]);

    $this->belongsTo('Users', [
        'foreignKey' => 'created_by',
        'joinType' => 'INNER'
    ]);

}

我用过这个。

$connection = ConnectionManager::get('default_history');
$this->OrderHistory = TableRegistry::get('OrderHistory');
$this->OrderHistory->setConnection($connection);
$id = 37;
$order_history = $this->OrderHistory->get($id, ['contain' => ['Users']]);

但无法成功。收到此错误：

Base table or view not found: 1146 Table 'default_history.users' doesn't exist

Answer 1

在 OrderHistoryTable.php 文件上试试这个：

$this->setTable('default_history.order_history');

Answer 2

几天前我遇到了同样的问题，

您的 BelongTo 中必须有 'strategy' => 'select' 才能加入其他数据库

 $this->belongsTo('Users', [
        'strategy' => 'select'
        'foreignKey' => 'created_by',
        'joinType' => 'INNER'
    ]);
