When finishing chapter 5 exactly as instructed, with no RSpec failures, I did the final steps to git add ., git commit and git push. Then did the git push heroku. It appeared successful and when I went to the Heroku site to test (http://stark-falls-6972.herokuapp.com/) it fails saying “We’re sorry, but something went wrong.”

The Heroku logs command does not indicate that anything went wrong, though there is a message about depreciating plugins, which, I’ve not seen until today. How do I fix this?

Make sure your app works locally. i.e. when you access it from localhost:3000

The relevant error message in the heroku stack trace above is ActiveRecord::ConnectionNotEstablished (ActiveRecord::ConnectionNotEstablished)

So Heroku is not able to connect to the database. Check to make sure you have followed all the previous heroku set-up related configurations.

Heroku supports postgresdb; so the pg gem has to be included in the Gemfile as detailed in this listing

Check these heroku deployment steps as well, particularly the $ heroku run rake db:migrate step. (No harm in repeating this step).

Here is a Stack Overflow thread which deals with the same error message in detail: Ruby – ActiveRecord::ConnectionNotEstablished
Hopefully that page will direct you towards the correct answer.
