Twig Extensions

The bundle comes with several twig extensions

System Indicator

The system indicator twig extension gives you a short overview about the system status in the sonata header:

Extend the Sonata Admin standard_layout.html.twig to enable the twig function in the backend header:

{% block sonata_top_nav_menu %}
    <div class="navbar-custom-menu">
        <ul class="nav navbar-nav">
            <li>
                {{ system_information_indicator()|raw }}
            </li>
        </ul>
    </div>
{% endblock %}

App Version

Displays the application version defined in the composer.json file:

{{ version() }}

Environment Indicator

The environment indicator gives you a fast indicator about the current environment:

Extend the Sonata Admin standard_layout.html.twig to enable the twig function in the backend header:

{% extends '@!SonataAdmin/standard_layout.html.twig' %}
{% block sonata_breadcrumb %}
    <ul class="nav navbar-nav" style="float:left">
        {{ environment()|raw }}
    </ul>
    {{ parent() }}
{% endblock %}

Extend the Sonata User login.html.twig to enable the twig function in the login screen:

{% extends '@!SonataUser/Admin/Security/login.html.twig' %}

{% block sonata_wrapper %}
    {{ parent() }}
    <ul style="position: absolute;top: 10px;left: 10px;">
        {{ environment()|raw }}
    </ul>
{% endblock sonata_wrapper %}
