I'm just getting started with Ruby and the Shopify_app gem. I've followed all the tutorials to the word on getting the demo app up and running, but I'm hit a wall. When I run my local server the install app screen shows up and then I type in the subdomain and it's all fine and dandy. However, when the app does it's call back to localhost:3000/login/finalize it just times out and nothing happens. The app does show up as installed on my test store. From what I can see from digging through my controllers I'm completely missing login_controller? When using shopify_app to generate in rails it also asks me to overwrite a lot more files than are mentioned in the tutorial. Not sure what to do? I would REALLY appreciate any help anyone can offer!!
