Validators bleeding from one model into another.

can you list all your 11 validations. I randomly added 5 validations and I am getting the count as 5.

validates_presence_of :first_name, :last_name, :address1, :city, :state, :zip_code, :phone_number,

                            :if => Proc.new { |user| user.signup_step > 0 }

validates_numericality_of :zip_code, :phone_number,

                            :if => Proc.new { |user| user.signup_step > 0 }

How's this for weird:
(rdb:3) p Piece.validators.count 40
(rdb:3) p User.validators.count 40
(rdb:3) p MembershipRequest.validators.count 40
(rdb:3) p Artist.validators.count 41
(rdb:3) p MembershipRequest.validators.count 41

!?

Neeraj, did you try two models, five validations each?

what version of rails you are using?

works fine for me

ruby-1.8.7-p249 > User.validators.count
 => 2 
ruby-1.8.7-p249 > Comment.validators.count
 => 2 
 ActiveRecord::Schema.define(:version => 20100625031507) do

   create_table "comments", :force => true do |t|
     t.string "first_name"
     t.string "last_name"
     t.string "address1"
     t.string "city"
     t.string "state"
     t.string "zip_code"
     t.string "phone_number"
   end

   create_table "users", :force => true do |t|
     t.string "first_name"
     t.string "last_name"
     t.string "address1"
     t.string "city"
     t.string "state"
     t.string "zip_code"
     t.string "phone_number"
   end

 end
 class Comment < ActiveRecord::Base
   validates_presence_of :first_name, :last_name, :address1, :city, :state, :zip_code, :phone_number,:if => Proc.new { |user| user.signup_step > 0 }

   validates_numericality_of :zip_code, :phone_number,
   :if => Proc.new { |user| user.signup_step > 0 }

 end
 class User < ActiveRecord::Base
   validates_presence_of :first_name, :last_name, :address1, :city, :state, :zip_code, :phone_number,:if => Proc.new { |user| user.signup_step > 0 }

   validates_numericality_of :zip_code, :phone_number,
   :if => Proc.new { |user| user.signup_step > 0 }

 end
 #rails -v : Rails 3.0.0.beta4

(rdb:1) p User._validators == MembershipRequest._validators
true

Seems like that's the root of the issue. I see that this uses the new class_attribute :_validators

It makes sense that if this class_attribute subclassing were to malfunction I would see the errors I'm getting. Obviously it works for you, but I can't pinpoint what else I may have done to break class_attribute.

I get the same results for 3.0.0.beta4 & 3.0.0.beta3

Looks like that did it! Rest of my gems aren't happy with edge so can't test the actual failure, but at least the objects aren't sharing validators.

Yikes. That was a scary one.
