title: Devise redirect path after sign-up and before confirmation
body: <p>I have implemented the devise gem on my app and I want to redirect to a specific path after sign_up. I have this method in the registration_controller.rb but its does not work, it redirects to the root path instead of the specified path. I also have <code>devise :confirmable</code> set up but I'm delaying the sent confirmation email until later.</p>
  
  <pre><code>def after_sign_up_path_for(resource)
    new_transaction_path(session[:registration_params])
  end
  </code></pre>
  
  <p>And returns the following flash notice: <code>translation missing: en.devise.registrations.store.signed_up_but</code></p>
  
  <p>How can I make this work?</p>
