Hello,
I''m trying to cut down the errors if the guy already getting the empty
nickname, so he doesn''t get anything about the nickname is short.
validates_presence_of :nickname
This below is not working ?
validates_length_of :nickname, :within => 4..40, :if => Proc.new {
|user| user.nickname.length > 1 }
nor this one below?
validates_length_of :nickname, :within => 4..40, :if =>
nickname.length> 1
Anyone have a solution for this?
Thanks :)

validates_presence_of :nickname validates_length_of :nickname, :in => 4..40, :allow_nil => true but just make sure that you change the nickname param from "" [empty string] to nil or it won''t work. "".nil? => false. I dunno why there''s not a :allow_blank => true which could cover nil? and empty?

But this are not working? Your example are not working either, it gives me "undefined local variable or method ''allow_nil''" ? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Perhaps you have other errors? I dunno how else to help. Here''s the API page for validates_length_of which clearly states that :allow_nil is a valid parameter. http://api.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#M000942 Sigh.
