To eliminate N + 1, use includes (: tags) and then call [tags] 1 instead of [tag_list].
#Calling tags
Model.includes(:tags).each{|m| m.tags }
# acts_as_When using taggable skills etc.
Model.includes(:tags).each{|m| m.skills }
# tag_If you call list, N+1 will inevitably occur
# Model.includes(:tags).each{|m| m.tag_list }
# tag_To be the same as list...
Model.includes(:tags).each{|m| m.tags.map(&:name) }
