Hi, I need to use validates_uniqueness_of only when inserting new records but not when update them. I use the following line of code, validates_uniqueness_of :type_id, :scope => [:user_name], :unless => :update, :message => "This has already been registered" But still it doesn''t run validations and allow duplicate inserts. Thanks in advance for your feedback. BR, Shiran -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi,
As you need to fire uniqueness validation during creation of new
record.
validates_uniqueness_of :type_id, :scope => [:user_name],:on =>
:create, :message => "This has already been registered"

Another technique which may be overkill for what you need is doing something like this... Say you have a very simple user signup but, after signup they have to fill in a more extensive user profile which has many more fields. I''ve solved this by doing: class User < ActiveRecord::Base validates_presence_of :login, :email validates_presence_of :password, :unless => :password_set validates_presence_of :password_confirm, :unless => :password_set validates_length_of :password, :within => 4..40, :unless => :password_set validates_confirmation_of :password, :unless => :password_set validates_length_of :login, :within => 3..40 validates_length_of :email, :within => 3..100 validates_uniqueness_of :login, :email, :case_sensitive => false validates_as_email :email end # This handles the User Form validations class UserForm < User validates_presence_of :first_name validates_presence_of :last_name end When doing things that require first, last name just use the UserForm object instead.
