active_record_instance_callbacks.rb
# This module allows to have an after_commit callback
# on a single AR instance. This is really useful in services.
#
# Usage example :
# mate = Mate.first
# mate.after_commit { |m| notify_first_name_changed(m) }
# mate.update_attributes!(first_name: "Gunter")
#

end
def _run_commit_callbacks

return if @instance_after_commit_callback.nil?
