Heroku アカウントで作成した MongoHQ データベースに接続するように、MongoMapper を使用して Rails3 アプリケーションを構成しようとしています。現在、コードを Heroku にプッシュすると、Mongo::AuthenticationError でクラッシュします。ログからのスタック トレースは以下のとおりです。
TLDR /app/vendor/bundle/ruby/1.9.1/gems/mongo-1.9.2/lib/mongo/db.rb:175:in `issue_authentication': Failed to authenticate user 'heroku' on db 'app19340960' (Mongo::AuthenticationError)

私の問題は、MongoMapper 接続を作成しようとする初期化ファイルに関係していると思います。コードは次のとおりです。ここにもあります。
db_config = YAML::load(File.read(Rails.root.to_s + "/config/database.yml"))
if db_config[Rails.env] && db_config[Rails.env]['adapter'] == 'mongodb'
mongo = db_config[Rails.env]
MongoMapper.connection = Mongo::Connection.new(mongo['hostname'])
MongoMapper.database = mongo['database']
end
新しい MongoMapper 接続を定義する行に何か問題があると確信しています。ロード元の database.yml ファイルは次のとおりです。
defaults: &defaults
host: 127.0.0.1
port: 27017
adapter: mongodb
development:
<<: *defaults
database: qwikstubs-dev
test:
<<: *defaults
database: qwikstubs-test
production:
<<: *defaults
uri: <%= ENV['MONGOHQ_URL'] %>
database: qwikstubs
username: <%= ENV['MONGO_USERNAME'] %>
password: <%= ENV['MONGO_PASSWORD'] %>
これがおそらく単純な解決策であることはわかっていますが、ここで 2 つと 2 つを組み合わせる方法がよくわかりません。MongoHQ アプリケーションを使用したい場合、何を変更する必要がありますか? その初期化ファイルは、Heroku と MongoHQ を使用しても必要ですか?
どんな助けでも大歓迎です！
