Hello,
I have an embedded app in rails 3.2.18 that works fine. I have made a copy to update to rails 4.1 but the application doesn't works. The <iframe> tag shows nothing.
I have make an empty app with this code https://github.com/shopify/shopify_app (that works in rails 4.1) and then I have embedded the app with this changes:
- Create common/iframe_redirect
- In session_controller.rb: change def authenticate to works with iframe_redirect
- Add link to app.js script and add the ShopifyApp.init script to the header of my layouts/application.html.erb
And the problem is the same, the <iframe> tag shows the <header> and <body> tags empty and rails doesn't shows errors.
I need help to continue developing, thank !!
