Extending EntityType to access Entity - symfony

Question

I'd like access to the instance of the entity when using an EntityType::class. I have a form like below:
->add('fooBars', MyNewType::class, [
'class' => FooBar::class,
'choices' => $fooBars,
'label' => 'Foo Bar',
'multiple' => true,
'expanded' => true,
'required' => false,
'by_reference' => false,
]);
I've created a new type which has the parent of entity type, I then have a custom template as well. Having followed this I have my entity type displaying but where I'm looping over the children, I don't know how to access the entity.
{% block foo_bar_widget %}
{% spaceless %}
{% if expanded %}
<ul {{ block('widget_container_attributes') }}>
{% for child in form if not child.rendered %}
<li>
{{ form_widget(child) }}
{{ form_label(child) }}
</li>
{% endfor %}
</ul>
{% else %}
{{ block('choice_widget') }}
{% endif %}
{% endspaceless %}
{% endblock %}
I'd like to call a method on the entity it's looping over but I'm unsure how to access it. I can't dump child as it produces too much.

Answer 1

This can be achieved using the following:
{% set entity = form.vars.choices[child.vars.value].data %}
So the complete block may look like:
{% block foo_bar_widget %}
{% spaceless %}
{% if expanded %}
<ul {{ block('widget_container_attributes') }}>
{% for child in form if not child.rendered %}
{% set entity = form.vars.choices[child.vars.value].data %}
<li>
{{ form_widget(child) }}
{{ form_label(child) }}
</li>
{% endfor %}
</ul>
{% else %}
{{ block('choice_widget') }}
{% endif %}
{% endspaceless %}
{% endblock %}
And now you can call entity methods like so:
{{ entity.name }}}
