Question

我正在使用多个两个名为'default'和'default_history的数据库。在“默认”数据库下，我有一个名为“食谱”的表，在“默认历史”数据库下有一个“ order_detail_history”。我有名称为OrderDetailHistoryTable的模型表。这是我的模型表：-

public static function defaultConnectionName()  
{
    return 'default_history';
}

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

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

    $this->belongsTo('RecipesLeft', [
        'strategy' => 'select',
        'propertyName' => 'Recipes',
        'className' => 'Recipes',
        'foreignKey' => 'recipe_id',
        'joinType' => 'LEFT'
    ]);
}

我正在使用查询：-

$recipe_list_history = $this->OrderDetailHistory->find('list', ['keyField' => 'RecipesLeft.id', 'valueField' => 'RecipesLeft.recipe_name'])->select(['RecipesLeft.id', 'RecipesLeft.recipe_name'])->contain(['RecipesLeft'])->where(['OrderDetailHistory.order_id' => $history_id])->order(['OrderDetailHistory.id'])->hydrate(false)->toArray();

并且我收到此数据库错误：-

Column not found: 1054 Unknown column 'RecipesLeft.id' in 'field list'
SELECT RecipesLeft.id AS `RecipesLeft__id`, RecipesLeft.recipe_name AS `RecipesLeft__recipe_name` FROM order_detail_history OrderDetailHistory WHERE OrderDetailHistory.order_id = :c0 ORDER BY OrderDetailHistory.id

我在模型表中定义了关联，但是我无法通过order_detials_history加入配方表。！

您的食谱表似乎没有id列（主键）。您可以发布三个表的数据库方案吗？
