Symfony4 twig for loop through variable variable

Question

i have a lot of sub entities, so i want to add/update them reusing one controller, view. So i need before every form print out list of sub entities already created. Sub entity name is variable

{% form_theme form 'bootstrap_4_horizontal_layout.html.twig' %}
<table class="table">
    {% for entity in parentEntity.{{  subEntityName }} %}
    <tr>
        <td>{{ entity }}</td>
    </tr>
{% endfor %}
</table>
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}

But this is not working, also

~ subEntityName ~

Not works

Found solution

{% set entities =  attribute(parentEntity, entityName) %}
{% for entity in entities %}
<tr>
    <td>{{ entity }}</td>
</tr>
{% endfor %}

And this works for me like a charm!

Instead of creating a new variable entities, you can also simply do:

{% for entity in attribute(parentEntity, entityName) %}

And instead of using the attribute function, you can use the bracket notation, at least if parentEntity is an array:

{% for entity in parentEntity[entityName] %}
