How to skip ActiveRecord callbacks?

I have model like this

class Vote < ActiveRecord::Base  
    after_save :add_points_to_user

    .....
end

Is it possible to somehow force model to skip calling add_points_to_user when saved? Possibly something like ActiveRecord#delete vs ActiveRecord#destroy?

For Rails 3, ActiveSupport::Callbacks gives you the necessary control. I was just facing the same challenge in a data integration scenario where normally-desirable-callbacks needed to be brushed aside. You can reset_callbacks en-masse, or use skip_callback to disable judiciously, like this:

Vote.skip_callback(:save, :after, :add_points_to_user)

..after which you can operate on Vote instances with :add_points_to_user inhibited

The following applies to rails 2, rails 3 and rails 4:

http://guides.rubyonrails.org/v3.2.13/active_record_validations_callbacks.html#skipping-callbacks

It provides a list of methods that skip callbacks, explaining why it is dangerous to use them without careful consideration. Reprinted here under the provisions of the Creative Commons Attribution-Share Alike 3.0 License.

For Rails 2, but not Rails 3 you can use these:

object.send(:create_without_callbacks)
object.send(:update_without_callbacks)

This will skip your validations:

vote.save(:validate => false)

more info http://guides.rubyonrails.org/active_record_validations_callbacks.html#running-callbacks">here</a>

To skipping your callbacks and validations, you can use, update_column v(3.1), or update_all

vote = Vote.first
vote.update_column(:subject, 'CallBacks')

Aparentlly this only works with ActiveRecord 3.1

Or:

Vote.where('id = ?', YourID).update_all(:subject => 'CallBacks')

In the end you have also i finally option and this will skip everthing:

execute "UPDATE votes SET subject = 'CallBacks' WHERE id = YourID"

OK the last one it's not so pretty.
