story is a Hash, not a Sequel::Model. You are calling Hash#update,
which updates the Hash, but does not change the database. What you want
to do is:

# Filter to just the record, then update
DB[:feed_items].filter(:id=>story[:id]).update(:content_grabbed =>
'1')

Or you could just use a model, which will do basically the same thing.

Just change the table you are using, and assuming the record would be
new in that table:

DB[:feed_items2].insert(story)

You need to post the error you are getting with a traceback in order to
provide adequate support.
