I am creating an online store. I have a performance problem if I use the twig function "render" instead of "include".
Here is the code that displays a product catalog:
catalog controller:
<?php
// src/Acme/StoreBundle/Controller/Product/Catalog.php
namespace Acme\StoreBundle\Controller\Product;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
class CatalogController extends Controller
{
/**
* @Template()
*/
public function productAction(\Acme\StoreBundle\Entity\Product\Category $category)
{
$qb = $this->getDoctrine()
->getRepository('StoreBundle:Product')
->createQueryBuilder('product')
->select('partial product.{id, token, name}')
->innerJoin('product.categoryRelation', 'categoryRelation')
->where('categoryRelation.category = :category_id');
$qb->setParameters(array(
'category_id' => $category->getId(),
));
$products = $qb->getQuery()
->getResult();
return $this->render('StoreBundle:Product\Catalog:product.html.twig', array(
'category' => $category,
'products' => $products,
));
}
}
... template for catalog controller:
{# src/Acme/StoreBundle/Resources/views/Product/Catalog/product.html.twig #}
{% extends 'AcmeDemoBundle::layout.html.twig' %}
{% block content %}
<h1>{{ category.name }}</h1>
<ul>
{% for product in products %}
<li>
{#% render "StoreBundle:Product:show" with { product: product } %#}
{% include "StoreBundle:Product:show.html.twig" with { product: product } %}
</li>
{% endfor %}
</ul>
{% endblock %}
... product controller:
<?php
// src/Acme/StoreBundle/Controller/Product.php
namespace Acme\Enter\StoreBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Enter\StoreBundle\Entity\Product;
class ProductController extends Controller
{
/**
* @Template()
*/
public function showAction(Product $product)
{
return array('product' => $product);
}
}
... simple (but more complex in future) template for product controller:
{# src/Acme/StoreBundle/Resources/views/Product/show.html.twig #}
{{ product.name }}
So if I use:
{% include "StoreBundle:Product:show.html.twig" with { product: product } %}
...all ok: 147ms and 4608Kb memory.
But when I need a controller to display the product:
{% render "StoreBundle:Product:show" with { product: product } %#}
...my script consumes too much time and memory: 3639ms and 17664Kb memory!
How to increase speed and reduce memory consumption by using the controller?
