Why is my mongoDB hosting uri settings for mongoid.yml not working correctly?

Question

I'm currently using the following settings (which does not work) in my mongoid.yml and i've correctly added the MONGOLAB_URI environmental variable to my heroku environment:

production:
  sessions:
    default:
      another:
        uri: <%= ENV['MONGOLAB_URI'] %>

I also tried the following which does not work:

production:
  uri: <%= ENV['MONGOLAB_URI'] %>

This also does not work:

production:
  sessions:
    default:
      uri: <%= ENV['MONGOLAB_URI'] %>

I'm getting the following error on the heroku push:

Running: rake assets:precompile
       There is a configuration error with the current mongoid.yml.
       Problem:
       No database provided for session configuration: :default.
       Summary:
       Each session configuration must provide a database so Mongoid knows where the default database to persist to. What was provided was: {"another"=>{"uri"=>nil}}.
       Resolution:
       If configuring via a mongoid.yml, ensure that within your :default section a :database value for the session's default database is defined.
       Example:
       \_\_development:
       \_\_\_\_sessions:
       \_\_\_\_\_\_default:
       \_\_\_\_\_\_\_\_database: my_app_db
       \_\_\_\_\_\_\_\_hosts:
       \_\_\_\_\_\_\_\_\_\_- localhost:27017

What am I doing wrong here? I've followed the mongoid.org instructions:

http://mongoid.org/en/mongoid/docs/installation.html

I am using mongoid 3.0.0.rc

Try this

ENV['MONGOLAB_URI'] = ds053681.mongolab.com:97321

production:
  sessions:
    default:
      hosts: 
        - <%= ENV['MONGOLAB_URI'] %>
      database: testapp_production
      username: testappuser
      password: testpassword

abhas's example didn't work for me. This is what finally worked:

production:   
  sessions:
    default:
      uri: <%= ENV['MONGOHQ_URI'] %>
      options:
        skip_version_check: true
        safe: true
