How in symfony 3.4 to display the login (or any data) in the base template?

Question

symfony

Hello! When creating routes in the controller, I can pass the variables I need to the template I need:

//...

        return $this->render('@App/some.html.twig', [
            'some_key' => $some_var,
        ]);

//...

The template itself extends another @App/layout.html.twig.

{% extends '@App/layout.html.twig' %}

{# ... #}

{% block body %}

    {{ some_key }}

{% endblock %}

{# ... #}

How can I pass the variables I need to @App/layout.html.twig ? For example user login or other kind of data?

1. Rendering a controller inside a template
https://symfony.com/doc/3.4/templating/embedding_c...

{{ render(controller(
    AppBundle:Article:recentArticles',
    { 'max': 3 }
)) }}

2. Custom Twig Extension that adds a function that implements the desired logic
https://symfony.com/doc/3.4/templating/twig_extens...
3. If you need to display something simple, for example, the application version, then you can use global variables
https://symfony.com/doc/3.4/templating/global_vari...
4. Some things are available in a global variable app, for example, the same instance of the logged in user
This is true for all versions of Symfony
