SetCounters

Similar to ARModel.update_counters, ARModel.set_counters simply sets multiple fields to their integer values. No adding/substracting, just setting. Yes, this could be done using update_all, but this seems nicer to me.

Add this line to your application's Gemfile:

gem 'set_counters'

And then execute:

$ bundle

Or install it yourself as:

$ gem install set_counters

# For the Post with id of 5, set the comment_count to 1, and
# set the action_count to 2

Post.set_counters 5, :comment_count => 1, :action_count => 2

# Executes the following SQL:
# UPDATE posts
#    SET comment_count = 1,
#        action_count = 2
#  WHERE id = 5

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request
