Q:

Rails tutorial mhhartl toy_app successful deployment on heroku, unable to retrieve page

I hope life's great and you're busy coding.
I am following mhartl's Rails tutorial for I am really eager to learn RoR for web app development. I tried to troubleshoot by starting from scratch several times which had me going through the pain of creating new bitbucket repos and so on. Anyways I felt you guys probably faced this already so you might be able to help.
After all the steps in the tutorial, up to 2.1, which is
$ git commit -am "Add hello"
$ heroku create
$ git push heroku master

and seems to be successful given the shell message below:
remote:        https://fast-sea-56609.herokuapp.com/ deployed to Heroku
remote: 
remote: Verifying deploy... done.
To https://git.heroku.com/fast-sea-56609.git
 * [new branch]      master -> master

when I go to the URL, I get this screenshot with the message
The page you were looking for doesn't exist.
I checked this post Unable to see Ruby on Rails App deployed on Heroku? and I solved the localhost:3000 db migration thingy so now I have localhost:3000/users displaying properly but the heroku url does not display any different.
Tell me if I can provide more informations or run anything to help you troubleshoot. Thanks for the time you spent on reading this rather than doing anything else.

A:

As you have mentioned that you are following Michael Hartl Rails Tutorial I suggest you to complete each task or chapter till the end.
Here the problem caused might be because you missed a part of your tutorial, that the autor ask you to complete the first applications step again with your toy application like bellow:
I suggest doing by following the same “hello, world!” steps in Listing 1.8 and Listing 1.9.1(Did you do these steps in your application before committing and pushing to heroku ?) Then commit the changes and push up to Heroku:
$ git commit -am "Add hello"
$ heroku create
$ git push heroku master

Once you finish making the first working copy of you Rails app in local the next step is to deploy it in heroku to test your app in production environment.
Yo can follow the official Heroku guide to know more about deploying an application into heroku
