Symfony主义返回空对象

Question

I'm trying to return a specific row in my table using Doctrine in conjunction with Symfony 2 and Vue 2. Here is the code I'm using to achieve this.

/**
 * Get all children of the administrator
 * @return JsonResponse
 */
public function getChildrenAction() {

$em = $this->getDoctrine()->getManager();

$records = $em->getRepository('TestUserBundle:NameOfEntity')-> 
findOneBy(array('id' => 123456));

return new JsonResponse($records);

}

My problem is that on the front-end, I always end up with an empty object such as {}, and can't do anything with that. Now I know this is returning the instance of that User, but I want all the data associated with that user in the table row on the front-end, so that I can use it to show specific user details. I know how to pass specific parts of the object, such as Id by tacking on "->id" or "->getId()", but have no clue how to get the whole object. Any help with this, or a gentle shove in the right direction would be greatly appreciated!

Answer 1

FindOneBy method returns a entity object according with the criteria given, if you want get that data from your view (twig template)

function doAction(){

  //...
  $this->render('some_template.html.twig', ['record' => $record ]);
}

some_template.html.twig

{{ dump(record) }}

Or if you wish return a response without a template, you could use JsonResponse class.

return new JsonResponse($records);

The JsonResponse class sets the Content-Type header to application/json and encodes your data to JSON when needed.
