Mongodb rest support

[reed.clarke]

Problem: Using "yiisoft\yii2\rest" on a mongodb collection results in and empty object being displayed "{}".

Cause: MongoId object with "$id" returned in result set.

Suggested Solution: Modify "yiisoft\yii2\data\ActiveDataProvider" class as follows:

/**


 * @inheritdoc


 */


protected function prepareModels()


{


    if (!$this->query instanceof QueryInterface) {


        throw new InvalidConfigException('The "query" property must be an instance of a class that implements the QueryInterface e.g. yii\db\Query or its subclasses.');


    }


    $query = clone $this->query;


    if (($pagination = $this->getPagination()) !== false) {


        $pagination->totalCount = $this->getTotalCount();


        $query->limit($pagination->getLimit())->offset($pagination->getOffset());


    }


    if (($sort = $this->getSort()) !== false) {


        $query->addOrderBy($sort->getOrders());


    }


    /* START CHANGE */


    $results = $query->all($this->db);


    foreach ($results as $result) {


    	if(get_class($result['_id']) === "MongoId") {


    		$result['_id'] = (string)$result['_id'];


    	}


    }


    return $results;


    /* END CHANGE */


}

Ok, but you should never change framework functions. what you should do it overwrite the function with an own class

class MyActiveDataProvider extends ActiveDataProvider{

/**

 * @inheritdoc


 */


protected function prepareModels(){


    $results = parent::prepareModels();


    foreach ($results as $result) {


        if(get_class($result['_id']) === "MongoId") {


            $result['_id'] = (string)$result['_id'];


        }


    return $results;


}

}
