визуализировать шаблон веточки из шаблона веточки

Я пытаюсь сделать шаблон ветки внутри другого шаблона ветки, но он не работает. я получил эту ошибку:

Любая помощь будет оценена!

Во время рендеринга шаблона было сгенерировано исключение
несоответствие между загруженными и объявленными именами классов:
FLY \ BookingsBundle \ Controller \ postController vs
FLY \ BookingsBundle \ Controller \ PostController «) в
SonataUserBundle: Профиль: show.html.twig в строке 94.

show.html.twig

{% extends "SonataUserBundle:Profile:action.html.twig" %}
{% block body %}

{% block content %}

{{ render(controller('FLYBookingsBundle:post:new')) }}

{% endblock content %}

{% endblock %}
