I would like to inject inside the styles and scripts blocks in my layout new values, but from the embed block.
Of course it throws the error Calling "parent" outside a block is forbidden..
Is there any workaround ?
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 %}
(And I cant/wont use the blocks scripts and styles inside the list.html.twig. They are part of the datatable template, it will not make any sens to define theme in the list.html.twig.).
And sadly I cant use use because this function does not support dynamics properties, only strings.
From the doc :
Because use statements are resolved independently of the context passed to the template, the template reference cannot be an expression.
