title: ActiveSupport::SecureRandom.hex question? Rails and Ruby
body: <p>I have a question regarding the <code>ActiveSupport::SecureRandom</code> class\library.</p>
  
  <p><a href="http://apidock.com/rails/ActiveSupport/SecureRandom" rel="nofollow">http://apidock.com/rails/ActiveSupport/SecureRandom</a></p>
  
  <p>I'm writing an application that might need some Random tokens like those generated by <code>SecureRandom</code>.</p>
  
  <p>What about the Uniqueness of these tokens? Are these Tokens Unique in nature or should I be better off using a Unique constraint on my DB Column?</p>
  
  <p>Thanks!</p>
