Template tag for displaying a list of arbitrary models. Useful for life-stream kind of pages that display blog entries, links, photos etc ordered by date. Example
Usage: something like:
{% for object in object_list %}
{% display_excerpt object %}
{% endfor %}
Will look for app/model_excerpt.html by default, and fall back on a generic display_excerpt.html, or returns the object's string representation as a last fallback.
display_excerpt.html might look something like:
<a href="{{ object.get_absolute_url }}">{{ object }}</a>
Any model you throw at it should have a get_absolute_url and a string representation of some sort, so this gives you the bare minimum of a title and a link to a detail page.
display_excerpt takes an optional argument to set the template suffix. This might be handy for generating different formatting for feeds, for instance:
{% for object in object_list %}
{% display_excerpt object "feed" %}
{% endfor %}
This will look for app/model_feed.html to render the object.
Got lots of help from mattmcc on #django for this one, thanks!

register.simple_tag(display_excerpt)
