Question

I reading Rails Tutorial and created a Sample_App.

My code is available here: https://github.com/namic/sample_app

Heroku is running the app here: http://afternoon-mist-7865.herokuapp.com/

It works in test, development and production environment on my laptop, but Heroku denies me the joy with “We’re sorry, but something went wrong.”

Any suggestions?

Solution:
Add to Gemfile:
group :production do
gem ‘pg’
end

And remember to run bundle install without production, if you dont want postgresql local:
bundle install –without production

Answer 1

Check the logs and make sure you ran the migrations on heroku.

heroku run rake db:migrate
