Overriding blocks within included Twig templates

Question

Is there a generally \"good\" way to achieve this functionality? I have read about the \'use\' tag, which seems like the best option so far, but I still don\'t like that it

Answer 1

Improvement on @webberig's solution, that fixes blocks that are not overridden in all extending templates (comment by @HerrNentu'):

#base.html.twig
{% if block("page_title") is defined %}
     {% include 'elements/header.html.twig' with {page_title: block('page_title')} %}
{% else %}
     {% include 'elements/header.html.twig' with {page_title: null} %}
{% endif %}
{% block content %}{% endblock %}
{% include 'elements/footer.html.twig' %}

#header.html.twig
This is my header
{% if page_title is empty %}
Default Page Title
{% else %}
{{ page_title }}
{% endif %}

#index.html.twig
{% extends 'layouts/base.html.twig' %}
{% block page_title %} This is my overridden page title {% endblock %}
{% block content %} here is the index page content {% endblock %}
