ruby - When using acts-as-taggable-on gem in Rails, is it possible to delete orphaned tags? -

-

i deleted posts in app. tags still there. if delete posts tags won't deleted. how can detect , delete tags not linked posts?

there configuration setting can add config/application.rb make sure tags deleted when no longer used:

actsastaggableon.remove_unused_tags = true

you can put in initializer under config/initializers.
