Automatic index updating

[gom]

I'm just looking at haystack with solr for the first time and trying
to figure out if there is a way to update a model's index when new
instances of the model are created, or if there is a normal pattern
for keeping indexes up to date as new model data is created.

Essentially I have some third party data being queried every 5 min,
and from the results of that query I might see a list of new models to
be created. I'd like to index all the new models every time this
happens. I see that you can do something like:

from haystack import site
index = site.get_index(ModelA)
index.update() # or index.reindex()

I'm assuming it would be a dumb idea to, say, put this in a model's
post_save() method or something. Is there a common pattern for
automatically updating an index, short of running code similar to the
above at clever junctions or throwing it into cron? How is this
normally tackled?

Cheers
