I had a production app on Heroku - productionapp.heroku.com
So, I followed the steps to create a staging app for it:
1. heroku create stagingapp --remote staging
2. heroku config:add RACK_ENV=staging --app stagingapp
3. heroku addons:add mongohq:free --app stagingapp
4. In config/mongoid.yml -
add
staging:
uri: <%= ENV['MONGOHQ_URL'] %>
5. cp config/environments/production.rb config/environments/staging.rb
6. Add the MONGOHQ_URL in the mongohq.com connection.
6. git push staging master
The staging app is continuously crashing with the following backtrace:

You did not specify how you would like Rails to report deprecation notices for your staging environment,
please set config.active_support.deprecation to :log, :notify or :stderr at config/environment

I have tried and retried these steps again and again and end up hitting the same error. It would be great if you could help me out!
i guess you did not add the configuration properly, because this is the line that fails in mongoid
YAML.load(ERB.new(File.read(config_file)).result)[Rails.env].values.flatten.any?
