Extend parent block from embedded template
I want to inject new values inside the style and script blocks in the layout, but from the embedded block.
Of course, it will throw an error Calling "parent" outside a block is forbidden..
Is there any solution?
layout.html.twig：
<!DOCTYPE html>
<html>
<head>
{% block style %}
<link rel="stylesheet" href="foo.css">
{% endblock %}
</head>
<body>
{% block content "" %}
{% block scripts %}
<script src="foo.js"></script>
{% endblock %}
</body>
</html>
list.html.twig：
{% extends 'layout.html.twig' %}
{% block content %}
{% embed datatable.html.twig %}
{% block tbody %}
<tr>
<td>my awesome table</td>
</tr>
{% endblock %}
{% endembed %}
{% endblock %}
datatable.html.twig：
<table id="myDatatable">
<tbody>
{% block tbody "" %}
</tbody>
</table>
{% block styles %}
{{ parent() }}
<link rel="stylesheet" href="dataTables.css">
{% endblock %}
{% block scripts %}
{{ parent() }}
<script src="dataTables.js"></script>
{% endblock %}
(I can't/won't use scripts and styles inside the list.html.twig block. They are part of the datatable template, in list.html.twig.).
Unfortunately I can't use use because this function doesn't support dynamic properties, only strings.
From the documentation:
Since use statements are parsed independently of the context passed to the template, template references cannot be expressions.
