Figure out how to make a script that (a) imports the model from your
pylons app (usually 'import myapp.models' should work) and (b)
connects to the database (I suggest using paste.deploy.appconfig to
parse the ini file and get the connection info)
Once you have that, you just have to loop over the newsgroup postings,
parse them, and store the parsed recipes in the database. The task of
determining which newsgroup postings should be parsed each run is
something you'll have to figure out for yourself.
You should be able to just put that in a cronjob, then.
My script (which was actually sending emails based on a table in the
db) works like this:
filename = "/Users/jon/code/myapp/development.ini"
app_conf = appconfig('config:'+filename)
meta.connect(app_conf['dsn'])
emaillist = objectstore.query(Email).select(limit=5)
for email in emaillist:
# actually send the email
# then mark the email as sent in the DB
