Is there an option to not touch the updated_at attribute when i update an attribute in mongoid ?
Something similar to model.save(validate: false) or, better, model.update_attribute(:attribute, 'value') ?
I just found my answer here : https://github.com/mongoid/mongoid/blob/v3.1.7/lib/mongoid/timestamps/timeless.rb
If anyone is interested, you can use model.timeless to skip updating created or update date, and model.clear_timeless_option to reactivate it !
