I keep finding places in my apps where I need an isolated snippet of text that can periodically be changed from the admin interface. Most often it's html but sometimes it's text, javascript, or css.
Use it like so:
(Assuming this snippet lives in snippy_snip/models.py and there is a snippet named "Welcome Message" in the database)
from snippy_snip.models import snip
msg = snip("Welcome Message")
Or, you might populate a parameter hash for a template:
def showpage(request):
params = {
'welcome': snip('Welcome Message'),
'video1': snip('Video 1'),
'NavHeader': snip('Nav.SectionHeader'),
}
return render_to_response("main.html", params)
For clarity, *params* might look something like this:
welcome -> "Welcome to our site. Please use the menu on the left..."
video1 - > a YouTube snippet
NavHeader -> Some HTML which comprises the top of a navigation menu.
This is a very simple bit of code but I've found it very useful. It isn't intended for instant changes... Your snippets will cache like anything else, which may cause confusion if you expect immediate changes. And it's probably not great for a high traffic site, but for my moderate traffic sites and workgroup apps I've found it useful.
(This code was created for 0.96, but I'm working to bring it into alignment with the latest svn version of Django, see comments.)

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](http://bjornkri.com)
**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!
