Can not nest {% static %} tag under if block in Django template

Question

I get Invalid block tag: 'static', expected 'endif' when I render the following template

{% load staticfiles %} <!-- in base.html -->/
 <!-- ... -->
{% block content %}
    {% if ava_url %}
        <div><img src="{{ava_url}}"></div>
    {% else %}
        <div><img src="{% static 'img/default_ava.png' %}"></div>
    {% endif %}
{% endblock %}

Why cannot I nest static under if?

Using Django 1.6.7

upd This is all in block container. Might be the reason. However when I remove if

{% load staticfiles %}  <!-- in base.html -->
 <!-- ... -->
{% block content %}

    <div><img src="{% static 'img/default_ava.png' %}"></div>

{% endblock %}

I get Invalid block tag: 'static', expected 'endblock'

upd solved. included {% load staticfiles%} in derived template. Sorry, it was not obvious, that {% load staticfiles%} was in base template in the first place. The answer was found here

However I need further explanation: why {% load staticfiles%} does not work from base template?

can you verify to see if there are no syntax errors in the base template? also, do you face this issue if you call this templatetag outside the `if` block ? — karthikr, Jan 20 '15 at 22:14
updated to answer. base template appears to work fine if I delete `static` tag — Sashko Lykhenko, Jan 20 '15 at 22:20
solved. Just wrote `load static` in the same file rather than in base one. But why `{% load staticfiles%}` does not work from base template? — Sashko Lykhenko, Jan 20 '15 at 22:53
Template tags only work on the template they are inherited in. They don't "trickle down" in scope to child templates. — Brandon Taylor, Jan 21 '15 at 00:12
`load static` is the proper syntax/call and as others have said, has to be called in each template that it is used; included templates can `load` their own tags — warath-coder, Jan 21 '15 at 04:08

Think of it like an import statement where the base template is a function within one module that is calling a function in another module, the derived template, with some parameters.

The "import" in the base template doesn't get inherited by the derived template and thus it needs to be "imported" with {% load ... %}
