我正在編寫一個Symfony2應用程序,允許移動用戶通過REST服務創建和更新「Homes」。我使用MongoDB作爲存儲層和Doctrine MongoDB ODM來執行文檔處理。Doctrine Mongo ODM合併外部修改數據
GET /homes/{key}
和POST /homes
方法工作正常。當我嘗試用PUT /homes/{key}
更新現有家庭時出現問題。
下面是當前的代碼:
/**
* PUT /homes/{key}
*
* Updates an existing Home.
*
* @param Request $request
* @param string $key
* @return Response
* @throws HttpException
*/
public function putHomeAction(Request $request, $key)
{
// check that the home exists
$home = $this->getRepository()->findOneBy(array('key' => (int) $key));
// disallow create via PUT as we want to generate key ourselves
if (!$home) {
throw new HttpException(403, 'Home key: '.$key." doesn't exist, to create use POST /homes");
}
// create object graph from JSON string
$updatedHome = $this->get('serializer')->deserialize(
$request->getContent(), 'Acme\ApiBundle\Document\Home', 'json'
);
// replace existing Home with new data
$dm = $this->get('doctrine.odm.mongodb.document_manager');
$home = $dm->merge($updatedHome);
$dm->flush();
$view = View::create()
->setStatusCode(200)
->setData($home);
$response = $this->get('fos_rest.view_handler')->handle($view);
$response->setETag(md5($response->getContent()));
$response->setLastModified($home->getUpdated());
return $response;
}
傳遞到操作的JSON字符串被成功地將反序列化的JMSSerializer我的文檔對象圖,但是當我試圖合併&齊平,我得到的錯誤:
Notice: Undefined index: in ..../vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/ClassMetadataInfo.php line 1265
我一直試圖在這裏遵循的文檔:http://docs.doctrine-project.org/projects/doctrine-mongodb-odm/en/latest/reference/working-with-objects.html#merging-documents
有S ^在嘗試合併之前需要對反序列化的Home做些什麼?合併錯誤的方法?
謝謝。
