Rails - May 2005 - validates_length_of && validates_presence_of: Duplicate error messages?

validates_presence_of :login , :on => :create, :message => "Please 
enter a login."
validates_length_of :login, :within => 3..40, :message => "Login must
be a minimum of 3 characters."

Right now if the login field is left blank, both these errors get 
thrown. I assume that setting a conditional for the first one if the 
second one is thrown, something like

validates_length_of :login, :within => 3..40, :message => "Login must
be a minimum of 3 characters.", :if => !:login?

Using the patch from http://dev.rubyonrails.com/ticket/1324. Is this 
accurate?
