У меня есть модель в Rails, пользователь. Каждый раз, когда я ссылаюсь на него (например, find_by_name("NAME") в script/console), его поле / атрибут last_login изменяется на текущее время.
Вот моя модель:
class User < ActiveRecord::Base
# ACCOUNT INFORATION VALIDATION
validates_presence_of :name
validates_uniqueness_of :name
validates_length_of :name, :in => 4..16
validates_format_of :name, :with => /^\w+$/i, :message => "can only contain letters, numbers and underlines."
validates_presence_of :password
validates_length_of :password, :in => 16..42, :message => "must be between 6 and 32 characters." #10 digits salt included
validates_presence_of :email
validates_uniqueness_of :email
validates_format_of :email, :with => /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z/i

self.damage-=1
if self.damage == 0
self.last_hp_recovery = nil

self.last_hp_recovery+=hp_recovery_time.minutes

end

self.energy_used-=1

Есть идеи, как и как это предотвратить?
