This is for Rails 3.1.1
I have a field called last_seen in a model. This field will be updated
when the something about the record is seen in the real world (don't
worry about this part)
So I go x.update_attribute(:last_seen, Time.now) and the following happens is
UPDATE "blah" SET "last_seen" = '2012-10-23 08:57:46.179288',
"updated_at" = '2012-10-23 08:57:54.872808' WHERE "blah"."id" = 2673
Now, just for this one attribute, I would like the updated_at field to
be unmolested. Is there some way of updating the last_seen field
without ActiveRecord updating the updated_at field?
update_column will do exactly what you're looking for, and has the advantage of not being on the short list to go away in Rails 4.1 like update_attribute. :)
