reset_counters(id, *counters, touch: nil) public

Resets one or more counter caches to their correct value using an SQL count query. This is useful when adding new counter caches, or if the counter has been corrupted or modified directly by SQL.


  • id - The id of the object you wish to reset a counter on.

  • counters - One or more association counters to reset. Association name or counter name can be given.

  • :touch - Touch timestamp columns when updating. Pass true to touch updated_at and/or updated_on. Pass a symbol to touch that column or an array of symbols to touch just those ones.


# For the Post with id #1, reset the comments_count
Post.reset_counters(1, :comments)

# Like above, but also touch the +updated_at+ and/or +updated_on+
# attributes.
Post.reset_counters(1, :comments, touch: true)
