Suggestions on how to track tag count for a particular object
- by Robin Fisher
Hi,
I'm looking for suggestions on how to track the number of tags associated with a particular object in Rails. I'm using acts_as_taggable_on and it's working fine. What I would like to be able to do is search for all objects that have no tags, preferably through a scope i.e. Object.untagged.all
My first thought was to use an after_save callback to update an attribute called "taggings_count" in my model:
def update_taggings_count
self.taggings_count = self.tag_list.size
self.save
end
Unfortunately, this does the obvious thing of putting me in an infinite loop. I need to use an after_save callback because the tag_list is not updated until the main object is saved.
Would appreciate any suggestions as I'm on the verge of rolling my own tagging system.
Regards
Robin
