Why variable does not exist in twig Symfony?

Question

I am trying to print all categories in my twig in this way:

 
                Categories
                
                    {% for category in categories %}
                    {{ category.name }}
                    {% endfor %}

But it tells me that variable categories does not exist.

Twig Structure:

{% extends 'base.html.twig' %}

{% block body %}
    
    

        

            
                Categories
                
                    {% for category in categories %}
                        {{ render(controller(
                                'AppBundle:Category:listCategories'
                            )) }}
                    {% endfor %}

When y try to do for in other template, it's working, but i want to do it in the homepage twig

Here is my controller:

public function listCategoriesAction()
    {
        $em = $this->getDoctrine()->getManager();
        $categoryRepository = $em->getRepository('AppBundle:Category');
        $categories = $categoryRepository->findAll();

       return $this->render('homepage/homepage.html.twig', array(
           'categories' => $categories->getResult()
       ));
    }

If you want render content in this variant:


{% for category in categories %}
 {{ category.name }}
{% endfor %}

You must generate this data in controller and return response:



    $em = $this->getDoctrine()->getManager();
    $categoryRepository = $em->getRepository('YouBundle:Category');
    $category = $categoryRepository->findAll();
    
    return $this->render(
    'MainBundle:Admin/page:order.html.twig',   
      [
        'categories' => $category->getResult(),
      ] );

Hear links in my test progect:
controller - TIK
template - TIK

Hope it's mast help.
