Here's one way to do this. It starts by naming your templates by
archetype.classname.lower(). For example:
TEMPLATE_DIR/<app_name>/archetype/article/default.html
TEMPLATE_DIR/<app_name>/archetype/bookreview/default.html
TEMPLATE_DIR/<app_name>/archetype/filmreview/default.html
TEMPLATE_DIR/<app_name>/archetype/default.html
That last one is just a default fallback template if you don't intend
to have custom templates for each classname.
Then, when you want to render an extended Node object:
from django.template.loader import render_to_string
default_tpl = "<app_name>/archetype/default.html"
node_tpl = "<app_name>/archetype/%s/default.html" %
node.archetype.classname.lower()
context = {'node':node}
rendered_string = render_to_string((node_tpl, default_tpl), context)
In article/default.html you know that the 'node' value in the context
represents an Article instance. So, you can grab fields from it that
you know are only available to an article. Similarly, you would know
what to do for bookreview/default.html and so on...
If you want to go further with this, you could build a template tag
that takes, the node instance or node.pk as a parameter and emits the
above rendered_string.
