There are still some problems in the usage of the tag. An as_tag adds
something to the context, so I wouldn't render anything in the tag. For
example, once you call {% page_teaser "about-us" as teased_page %}
teased_page is added to the context so you would access it like, {{
teased_page }}.
Try something like this:
https://gist.github.com/joshcartme/bcdda75f1607890587ca
btw, where is templatetags/page_teaser_tags.py? It should be inside an app
that is in your INSTALLED_APPS setting.
Good luck!
