Application error when deploying Sinatra app using DataMapper + postgres

StackOverflow https://stackoverflow.com/questions/22731990

Question

I'm trying to deploy a simple Sinatra app to Heroku, I'm using postgresql, my Gemfile looks like this:

gem 'sinatra'
gem 'data_mapper'
gem 'dm-postgres-adapter'
gem 'pg'
gem 'database_cleaner'
gem 'bcrypt-ruby'
gem 'rack-flash3'
gem 'sinatra-partial'
gem 'mandrill-api'

group :development, :test do
  gem 'capybara'
  gem 'shotgun'
  gem 'rspec'
  gem 'debugger'
end

I have the pg add-on on my app, This is how my datamapper_setup.rb looks:

env = ENV['RACK_ENV'] || "development"

DataMapper.setup(:default, ENV['DATABASE_URL'] || "postgres://localhost/bookmark_manager_#    {env}")

DataMapper.finalize

DataMapper.auto_upgrade!

I don't know how to interpret the logs from heroku but here they are:

2014-03-29T13:35:47.674101+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=staging-bookmarkmanager.herokuapp.com request_id=304ebd75-859f-4768-9766-f25ca2fdf3ba fwd="77.99.158.5" dyno= connect= service= status=503 bytes=

Any ideas on why is this happening? I've tried several approaches already with no luck.

Was it helpful?

Solution

In the additional logs you posted, it would seem that the database is refusing your connection:

FATAL:  role "xbwj…jedif" is not permitted to log in (DataObjects::ConnectionError)

Verify the that the credentials provided by ENV['DATABASE_URL'] are the same as those listed in the output of heroku config.
