title: Rails Stripe has no attached payment source error
body: <p>I am getting this error when I try to create a new customer using devise and stripe. As you can see in my parameters I have the stripe_card_token and it's NOT blank. However I am still getting a no attached payment error. I have also tried using :card => token instead, but still getting the same error.  </p>
  
  <p>What am I doing wrong? I am using this on heroku. Rails 4. Ruby 2</p>
