Why can't I nest a block tag inside an if tag?

Question

I have a master template file called base.html, in it I have the following code:

{% ifequal environment \"dev\" %}
    {% block stylesheets %}{%         


        

Answer 1

This question is no longer relevant - as of r12655 you can nest a block tag within a conditional.

Answer 2

Edit (14th October, 2010):

The original question title is no longer true, according to this comment on a ticket on Django.

Original Answer:

I'm not sure why not, but you could just do:

{% block stylesheets %}
    {% ifequal environment "dev" %}
        ... something ....
    {% else %}
        {{ block.super }}
    {% endifequal %}
{% endblock %}

Having rethought this a bit - I guess that means repeating that logic inside each of your templates, which is fairly unsatisfactory, but I'll leave this answer here anyway. I've had a quick look through the Django tickets and can't find anything relevant.
