title: Error when trying to deploy Stripe on Rails?
body: <p>I'm trying to hook up Stripe Checkout for a Rails app, but when I deploy it (both locally and on Heroku), I get:</p>
  
  <pre><code>NoMethodError in Builder#index.......undefined method `stripe' for #&lt;Rails::Application::Configuration:0x007ff403128b18&gt;
  </code></pre>
  
  <p>It says this is the code with the problem (second line is the one throwing the error): </p>
  
  <pre><code> &lt;script src="https://checkout.stripe.com/checkout.js" class="stripe-button"
     data-key="&lt;%= Rails.configuration.stripe[:publishable_key] %&gt;"
     data-description="A month's subscription"
     data-amount="500"&gt;&lt;/script&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>Any thoughts?</p>
