before_save()

Is called before Base.save (regardless of whether it’s a create or update save).

# File activerecord/lib/active_record/callbacks.rb, line 238
    def before_save() end

Don't call .save or .update_attribute on other objects inside before_save callback.

Saving other objects inside of before_save callback results in flushing changed hash and the original object is not updated.

UPDATE observed sometimes, still investigating
