Question

I have a block ‘left_area’ defined in a base appengine template

{% block left_area %}
   <div class="span3">
     Left area content
   </div> 
{% endblock %}

In a child template, I want to override this block inside an if

{% if not user %}
  {% block left_area %}
    <div class="span2">
    </div> 
  {% endblock %}
{% endif %}

This is not working for some reason. Any suggestion?

Answer 1

In jinja you can solve it with super(), which renders the parent block:

{% block left_area %}
    {% if not user %}
        <div class="span2">
        </div>
    {% else %}        
        {{ super() }}
    {% endif %} 
{% endblock %}
