我在将数据更新到 Yii2 中的表时遇到问题

Question

我的一位同事在 yii2 关系中使用了以下包。现在，有时在更新数据时，我遇到了以下错误。

Package link.

错误：

 "name": "Exception",
    "message": "Unable to link models: the link defining the relation does not involve any primary key.",
    "code": 0,
    "type": "yii\\base\\InvalidCallException",
    "file": "/app/vendor/yiisoft/yii2/db/BaseActiveRecord.php",
    "line": 1352,
    "stack-trace": [
        "#0 /app/vendor/la-haute-societe/yii2-save-relations-behavior/src/SaveRelationsBehavior.php(558): yii\\db\\BaseActiveRecord->link('metafields', Object(shopify\\models\\VariantMetafield), Array)",
        "#1 /app/vendor/la-haute-societe/yii2-save-relations-behavior/src/SaveRelationsBehavior.php(512): lhs\\Yii2SaveRelationsBehavior\\SaveRelationsBehavior->_afterSaveHasManyRelation('metafields')",

我的型号代码：

    public function behaviors(){
        
        $behaviors = parent::behaviors();
        
        $behaviors[] = [
            'class' => SaveRelationsBehavior::className(),
            'relationKeyName' => SaveRelationsBehavior::RELATION_KEY_RELATION_NAME,
            'relations' => [
                'images',
                'options',
                'variants', 
                'metafields',  
                'tags',
                'vendors',
                'productTypes' 
            ]
        ]; 
        return $behaviors;
    }

public function getMetafields(){
            
            $productMetafieldClass  = Yii::$app->factory->getClassByResource(Factory::PRODUCT_METAFIELD);
            
            return $this->hasMany($productMetafieldClass, [
                'owner_id'          => 'id',
                'consumer_id'       => 'consumer_id'
            ]);
        }

谁能帮我解决上述问题。 谢谢。

yii\db\ActiveRecord 的 link() 方法期望关系使用主键。 默认情况下，框架会从 db 架构中找到主键，但您的表没有任何主键。

您可以尝试在模型中覆盖 primaryKey() 方法，以使框架使用具有唯一索引的列作为主键，而不是在 db 架构中查找它们。

在你的模型类中

public static function primaryKey()
{
    return ['id', 'consumer_id'];
}
