Yay!!! It works like magic! Would anyone be so kind as to reveal the mysteries of this "Context ()" function? I'd love to know what this code is doing and why it fixes my problem.

The render() method takes a template.Context object, not a dictionary.
You want this:
ind.render(template.Context())

Can you paste us the code in your view that loads the template, passes it a context and renders it? If you're not sure what code I'm talking about, just paste us your whole view, if that's possible.

This comment is inaccurate. {% block %} tags are not required to have
any space between them. "{% block content %}{% endblock %}" -- with no
space -- is perfectly valid.

Django chokes on template blocks?
Hi guys, I'm trying to get my first django project off the ground but I've hit snag that I can't seem to get around. I've made a base.html template and an index.html template that extends the base (pretty standard stuff I think). But django barfs up this error: - AttributeError at / 'NoneType' object has no attribute 'push' - Huh? Here's a screenshot that should clarify: http://datafly.net/django-error.png Anybody got any idea why I can't use blocks in my templates? What am I doing wrong? :-) Sean --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
