我正在创建一个在线商店.如果我使用twig函数"render"而不是"include",我会遇到性能问题.

以下是显示产品目录的代码:

目录控制器:

<?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,
        ));
    }
}

...目录控制器的模板:

{# src/Acme/StoreBundle/Resources/views/Product/Catalog/product.html.twig #}
{% extends 'AcmeDemoBundle::layout.html.twig' %}

{% block content %}
    <h1>{{ category.name }}</h1>

    <ul>
    {% for product …
