symfony - Symfony3 Doctrine : Fetch entities as arrays with all associations for performance improvement -


i have 2 entities : product , tag. product can has 0 or 1 tag.

product entity :

/**  * @orm\column(type="string", length=25)  * @orm\id  */ private $code;  /**  * @orm\column(type="string", length=50)  */ private $name;  /**  * @orm\column(type="string", length=35, nullable=true)  */ private $tagcode;  /**  * @orm\manytoone(targetentity="tag")  * @orm\joincolumn(name="tagcode", referencedcolumnname="tagcode")  */ private $tag;

i have page want list products. use knppaginator bundle paginate 1000+ results (50 per page).

productcontroller listaction()

$em = $this->getdoctrine()->getmanager(); $query = $em->createquery('select p appbundle:product p order p.code asc');  // pagination $paginator  = $this->get('knp_paginator'); $pagination = $paginator->paginate($query, $request->query->getint('page', 1), 50);  return $this->render('products/list.html.twig', array(     'products' => $pagination ));

it works it's little bit time consuming (more 7 seconds display 50 first results).

instead of fetching products entities (my entities quite large lot of dependencies , associations), use arrays (for increasing page loading speed).

besides, want show properties of entity product.

  • product name
  • product code (= primary key)
  • tag code (= secondary key)
  • tag name

i tried use $query->getarrayresult() doesn't return tag object , have tag object show tag name in twig :

{% product in products %}     ...     <td>{{ product.tag.name }}</td>     ... {% endfor %}

$query->getarrayresult() returns array of products :

array (size=3)   'code' => string 'test' (length=4)   'name' => string 'my product' (length=10)   'tagcode' => string 'mytag' (length=5)

my question : how tag object (or tag name) in array of results ?
