When a template uses inheritance, it's possible to render the contents of the parent block when overriding a block by using the parent
function:
{% extends "base.html" %} {% block sidebar %} <h3>Table Of Contents</h3> ... {{ parent() }} {% endblock %}
The parent()
call will return the content of the sidebar
block as defined in the base.html
template.
