Почему консоль rails игнорирует мою конфигурацию config/database.yml: настройки?

Question

В моем файле database.yml задана нестандартная база данных: нет явного имени пользователя :. Если я использую rails c и попытаться получить доступ все, что он терпит неудачу с, например:

2.2.2 :001 > User.connection 
ActiveRecord::NoDatabaseError: FATAL: role "scope" does not exist 

Если я пытаюсь явно подключиться, используя мои: параметры развития я вижу:

2.2.2 :005 > ActiveRecord::Base.establish_connection :development 
=> 
#<ActiveRecord::ConnectionAdapters::ConnectionPool:... 
@config={:adapter=>"postgresql", :encoding=>"unicode", :database=>"scope", :pool=>5, :timeout=>5000, :port=>5432, :username=>"scope", :password=>"...", :host=>"127.0.0.1"}, 
... 

Так это явно игнорируя мою пользовательскую базу данных и мое собственное имя пользователя. Как ни странно, если я переименую блок yaml с development: на что-нибудь еще, например. staging:, я могу установить соединение с ActiveRecord::Base.establish_connection :staging и получить доступ к моим моделям.

Кто-нибудь знает, что может быть? У меня нет набора переменных окружения DATABASE_URL, поэтому это не может быть переопределяющим. Что еще может вызвать такое поведение?

Вот фактический YML:

development: 
    adapter: postgresql 
    encoding: unicode 
    database: mydb_development 
    pool: 5 
    timeout: 5000 
    port: <%= ENV["BOXEN_POSTGRESQL_PORT"] || 5432 %> 

И StackTrace:

2.2.2 :002 > User.count 
ActiveRecord::NoDatabaseError: FATAL: role "scope" does not exist

UPDATE Использование новой оболочки и подключения к консоли, казалось, магическим образом исправить положение. Я до сих пор не знаю, что изначально испорчены вещи, хотя ...

Try This:

development: 
    adapter: postgresql 
    encoding: unicode 
    database: XXX_development 
    host: localhost 
    pool: 5 
    username: yourusername 
    password: yourpassword
