Inheritance¶

Templates are able to extend other templates, allowing you to avoid duplication.

The base template much declare {% block %} which can be overriden. Each block has an unique name, which becomes a method on the class.

<!DOCTYPE html>
<html>
    <head>
        <title>{% block title %}default title{% endblock %}</title>
    </head>
    <body>{% block content %}{% endblock %}</body>
</html>

Any blocks not overriden by an inheriting template will default to their parent classes implementation, as you’d expect.

{% extends base.html %}
{% block title %}My Title {% endblock%}

The super tag allows you to access blocks from the parent class.

{% extends base.html %}
{% block title %}{% super title %} - Extra title{% endblock %}
