Mongo Connection Failure

I'm new to rails. I would like to push a simple rails application to cloudfoundry and I am getting an error:

 ====> /logs/stderr.log <====
/var/vcap/data/dea/apps/mytestapp-0
-4a068e3fd2b22422bdd29f3762e9bc9b/app/rubygems/ruby/1.9.1/gems/mongo-
1.6.4/lib/mongo/connection.rb:420:in `connect': Fail:27017  (Mongo::ConnectionFailure)

The sample app gemfile:

source 'http://rubygems.org'
gem 'rails', '3.0.5'
gem 'mongo_mapper'
gem 'bson_ext'

mongo.yml:

defaults: &defaults
host: 127.0.0.1
port: 27017

development:
<<: *defaults 
database: cloud_foundry_rails_tutorial_development

test:
<<: *defaults
database: cloud_foundry_rails_tutorial_test

# set these environment variables on your prod server
production: 
host: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-2.0'].first['credentials']['hostname']  
rescue 'localhost' %>

port: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-2.0'].first['credentials']['port']    
rescue '27017' %>

database: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-2.0'].first['credentials']['db'] 
rescue 'cloud_foundry_rails_tutorial' %>

username: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-2.0'].first['credentials']['username'] 
rescue '' %>

password: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-2.0'].first['credentials']['password'] 
rescue '' %>

I was able to push to CF last week without any issue but now it doesn't work? Is there something that changed on the CF side? Thanks

CloudFoundry.com upgraded from MongoDB 1.8 to 2.0 last week, and that's likely affecting your app. I will be checking with the CF.com engineering team and filing a bug if necessary.

However, since you're manually specifying connection information in mongo.yml, have you disabled auto-config of services? To do so, create the file config/cloudfoundry.yml and add:

autoconfig: false

For more information on auto-config of services in Ruby apps, see http://blog.cloudfoundry.com/2012/03/12/using-cloud-foundry-services-with-ruby-part-1-auto-reconfiguration/
