php - Symfony Assert DateTime JMSSerializer -

i have endpoint postorder - create entity order. in entity order have fields type datetime , want when write string instead datetime have "not valid, should datetime" . other fields use

 * @assert\length(min=3, max=255) 

or

 * @assert\regex(  *           pattern= "/^[\d() \-+]+$/",  *           message= "this text cannot contain numbers"  * ) 

or

     * @assert\notblank() 

i request serialize deserialize concrete entity when validate , have information assert in endpoint, datetime not work use fosrestbundle , jmsserializer action

 /**  * post order.  *  * @apidoc(  * resource = true,  * description = "post order",  *  parameters={  *      {"name"="comment", "datatype"="string", "required"=false, "description"="comment"},  *      {"name"="interview_date", "datatype"="date", "required"=false, "description"="date conect developer"},  *      {"name"="contact_date", "datatype"="date", "required"=false, "description"="date contact fir tim"}  *  *  },  * statuscodes = {  *      200 = "returned when successful",  *      400 = "returned secret token not valid"  * },  * section="order"  * )  *  * @restview()  *  * @param request $request  *  * @return view  *  * @throws notfoundhttpexception when not exist  */ public function postorderaction(request $request) {         $data = $request->request->all();         $data = $this->get('serializer')->serialize($data, 'json');         $servicelead = $this->get('serializer')->deserialize($data, 'artel\profilebundle\entity\codeservicelead', 'json');         $errors = $this->get('validator')->validate($servicelead);             if (count($errors) > 0) {                 $view = $this->view($errors, 400);                  return $this->handleview($view);             } 

and fields

class orders {       /**  * @var string  *  * @orm\column(name="comment", type="string", nullable=true)  * @groups({"get_all_orders_admin", "get_all_orders", "for_vip"})  */ protected $comment;      /**  * @var \datetime  * @orm\column(name="interview_date", type="date", nullable=true)  * @groups({"get_all_orders_admin", "get_all_orders", "for_vip"})  * @assert\datetime()  */ protected $interview_date;  /**  * @var \datetime  * @orm\column(name="contact_date", type="date", nullable=true)  * @groups({"get_all_orders_admin", "get_all_orders", "for_vip"})  * @assert\datetime()  */ protected $contact_date; 

now have error when try deserialize entity order

{ "error": { "code": 500, "message": "internal server error", "exception": [   {     "message": "invalid datetime \"some_string\", expected format y-m-d\\th:i:so.",     "class": "jms\\serializer\\exception\\runtimeexception", 

how return correct error or assert, without 500, in situation ?

when call deserialize(), checking entity validity against doctrine annotations since jms serializer already integrates doctrine orm.

if deserializing fails, exception thrown, seeing.

all need in case put code in try/catch block if want handle yourself:

public function postorderaction(request $request) {     $data = $request->request->all();     $data = $this->get('serializer')->serialize($data, 'json');      try {         $servicelead = $this->get('serializer')->deserialize(             $data,             'artel\profilebundle\entity\codeservicelead',             'json'         );     } catch (\exception $e) {         $view = $this->view((array) $e->getmessage(), 400);          return $this->handleview($view);     } } 

i didn't see view() function assumed expecting array of strings of error messages cast exception message array. either way idea.
