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?

I’m not so sure that’s entirely accurate. Check out the API for
update_attributes! and save! methods:

http://api.rubyonrails.org/classes/ActiveRecord/Persistence.html#method-i-update_attributes-21
http://api.rubyonrails.org/classes/ActiveRecord/Persistence.html#method-i-save-21

Specifically: update_attributes! updates its receiver just like
update_attributes but calls save! With save! validations always run.

Tim, I know that somethn going wrong. But don’t know, what.

I think you need to explain your problem more carefully. I do not
think anyone knows exactly what you are asking.

I think the OP is trying to save to the database without validaton and
is
confusing

  • update_attributes (which does perform the validations)
  • update_attribute (which can update an attribute in the db without
    validations)

This example might help:

class Referral < ActiveRecord::Base belongs_to :user validates :comment, :presence => true end

$ rails c
Loading development environment (Rails 3.1.1.rc1)
001:0> r = Referral.first
Referral Load (0.6ms) SELECT “referrals”.* FROM “referrals” LIMIT 1
=> #<Referral id: 3, user_id: 2, comment: “developer”, created_at:
“2011-10-11 10:56:14”, updated_at: “2011-10-11 10:56:14”>
002:0> r.update_attributes(:comment => nil)
(0.4ms) BEGIN
(0.3ms) ROLLBACK
=> false # FAILED (because of validation)
003:0> r.errors.messages
=> {:comment=>[“can’t be blank”]} # this is the validation that fails
004:0> r.update_attribute(:comment, nil)
(0.4ms) BEGIN
(1.0ms) UPDATE “referrals” SET “comment” = NULL, “updated_at” =
‘2011-10-16 15:43:22.544048’ WHERE “referrals”.“id” = 3
(1.3ms) COMMIT
=> true # the save succeeded, without checking the validation
005:0> r
=> #<Referral id: 3, user_id: 2, comment: nil, created_at: “2011-10-11
10:56:14”, updated_at: “2011-10-16 15:43:22”>

HTH,
