[Rails] Validates_with problem

I have one big problem: when I try record to db through
update_attributes! (which must save when record invalid). All good, all
validates :field, :presence => true et.c. field ignored, but
validates_with no ignore! So, it raises an error:

> Validation failed: Captcha wrong captcha input

CaptchaValidator works with many models, so I put it to
captcha_validator.rb

But I want to save with ignore this field. What I must do?
