Is there any way for a before_save filter to halt the entire save without halting the transaction? What I'm trying to do is have a "sample" version of my model that the user can interact with and save but the changes themselves are never actually saved. The following will halt the transaction and (naturally) return false when I call @model.update_attributes:

before_filter :ignore_changes_if_sample
def ignore_changes_if_sample
  if self.sample?
    return false
  end
end

Thanks!
