Don’t know if this will work, but try making a before_update filter
that finds the original object with the original updated_at and set
the object to that value…
something like
def before_update
original_record = Model.find(self.id)
self.updated_at = original_record.updated_at
end
Again, I don’t know if this is going to work. I’m guessing that the
updated_at is set by Rails after your before_update filter…
