Disclaimer: RoR newbie. Using the acts_as_taggable plugin. As an exercise I wanted to switch from the destructive TAG_WITH method to adding tags while preserving the existing ones. On the surface this seemed easy enough and eventually I got it working. However, the following method: def add_tags(list) Tag.transaction do Tag.parse(list).each do |name| if
