json_encode（）递归检测到Symfony2 JMSSerializerBundle

时间：2013-09-02 16:36:21

标签： symfony serialization entity jmsserializerbundle

我目前正在尝试公开群组以进行ajax通话。 如果我在每个字段上使用@Expose它就像一个魅力，但如果我用@Groups替换它会抛出在第29行的JsonSerializationVisitor.php中检测到的错误递归，并且我的ajax返回中的结果有一个＆＃39; null＆＃39 ;值。

Warning: json_encode() [function.json-encode]: recursion detected in /Applications/MAMP/htdocs/xxx-ref/vendor/jms/serializer/src/JMS/Serializer/JsonSerializationVisitor.php on line 29
{"datas":[{"datas":null,"errors":[],"redirect":null},{},{},{},{},{},{},{},{},{},{},{}],"errors":[],"redirect":null}

这是我对serializer =＆gt;

的调用 
$context = new SerializationContext(false, 1);
$context->setSerializeNull(true);
$context->setGroups(array('details'));
$response->setContent($this->get('serializer')->serialize(array( 'datas'=>$datas, 'errors'=>$errors, 'redirect'=>$redirect), 'json', $context));

这是使用的实体

我回答了我自己的问题

我只需要添加

@Expose

在群组注释之前。

/**
 * @ORM\Column(type="string", length=32, nullable=true)
 * @Expose
 * @Groups({"details"})
 */
protected $number;
