Hi Mike, excellent answer, thanks. Look, I followed this example:
http://www.djangrrl.com/view/custom-template-tags-in-django/
But my problem is that don't displays list categories, but neither I get
error. I copied exactly that appears in that article, but I don't have good
results.
Can you help me, please??!!
