Heroku Rails deployment successful but Application Error

*Edited

In trying to deploy my Rails 4 app onto Heroku, I kept getting error messages even though my deployment was successful. I also needed to translate my app from using sqlite3 to postgres (edits to database.yml) What helped me was running:

heroku logs -- myAppName

where as before, I was only doing:

heroku logs

An error I got was a MissingTemplate. I found that I needed to update my production.rb file to include:

config.assets.compile = true

and in my Gemfile

group :production, :staging do
    gem 'haml'
    gem 'rails_12factor'
end

Happy to announce that I was finally able to get this working! The problem was found by running: heroku logs -- appname

I needed to put haml in my production.rb file, and a few other tricky things were missing. Thanks a bunch!

The 5th last line of your console log is giving you the answer :)

2016-07-23T03:03:41.316258+00:00 app[web.1]: /app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.5.1/lib/active_record/connection_adapters/connection_specification.rb:248:in `resolve_symbol_connection': 'localhost' database is not configured. Available: ["host", "development", "test", "production"] (ActiveRecord::AdapterNotSpecified)

You can't use localhost on heroku. Try production instead
