Symfony2 include and access to the variables - symfony

Question

I dont have access to variables when try to include other file.
I try to add with keyword in include but dont work, all time i get message:
Variable "entity" does not exist in
ISLabBundlesBlogBundle:Post:last_post.html.twig at line 6
First i have indexAction() where i list all published blog post.
public function indexAction()
{
$posts = $this->getDoctrine()->getRepository('ISLabBundlesBlogBundle:Post')->getAllPublishedPosts();
return $this->render('ISLabBundlesBlogBundle:Page:index.html.twig', array(
'posts' => $posts
));
}
And have method where list only last posts
public function lastPostAction($count = 1)
{
$entity = $this->getDoctrine()->getRepository('ISLabBundlesBlogBundle:Post')->getLastPosts($count);
return $this->render('ISLabBundlesBlogBundle:Post:last_post.html.twig', array(
'entity' => $entity
));
}
Problem is in this file in block sidebar. I try to include other file where i fetch only 1 last post.
{% extends 'ISLabBundlesBlogBundle::layout.html.twig' %}
{% block body %}
{# Fetch all post#}
{% if posts %}
{% for post in posts %}
<article class="blog">
<div class="date"><time datetime="{{ post.created|date('c') }}">{{ post.created|date('l, F j, Y') }}</time></div>
<header><h2> {{ post.title }} </h2></header>
<p> {{ post.body }} </p>
</article>
{% endfor %}
{% endif %}
{% endblock %}
{% block sidebar %}
{% include 'ISLabBundlesBlogBundle:Post:last_post.html.twig'%}
{% endblock %}
And here is file what i try to include:
<h2>Last Posts</h2>
<div class="blog">
<ul>
{% for item in entity %}
<li>{{item.title}}</li>
{% endfor %}
</ul>
</div>
What i do wrong? And how to slove this?

Answer 1

You need to pass entity to your index template:
public function indexAction()
{
$posts = $this->getDoctrine()->getRepository('ISLabBundlesBlogBundle:Post')->getAllPublishedPosts();
$entity = $this->getDoctrine()->getRepository('ISLabBundlesBlogBundle:Post')->getLastPosts(1);
return $this->render('ISLabBundlesBlogBundle:Page:index.html.twig', array(
'posts' => $posts,
'entity' => $entity,
));
}
It's also possible (and probably better) to do this with an embedded controller:
{% block sidebar %}
{{ render(controller('ISLabBundlesBlogBundle:Post:lastPost', {
'count': 1
})) }}
{% endblock %}
