Rails 3 :uniqueness option spitting out syntax error

I'm trying to figure out why this uniqueness option keeps failing and have exhausted all the options. Anybody have any idea why this might be erroring out in rspec?

Many thanks,

Here is the user.rb code which it looks like this issue is stemming from..

 class User < ActiveRecord::Base
  attr_accessible :name, :email

  email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i

  validates :name,  :presence => true,
                    :length   => { :maximum => 50 }
  validates :email, :presence => true,
                    :format   => { :with => email_regex }
                    :uniqueness => { :case_sensitive => false }
end

Are you certain your syntax looks like this validates :name, :uniqueness => { :case_sensitive => false } ? Did you maybe forget the ',' ? Or use something other than symbols ?

(edit corresponding to code posting)

You need a comma between the validators, like so

validates :email, :presence => true,
                :format   => { :with => email_regex }, # notice the comma after the hash
                :uniqueness => { :case_sensitive => false }
