ActiveRecord :: StatementInvalid: Mysql2 :: Erreur: Aucune base de données sélectionnée: SHOW TABLES LIKE 'users'

Question

J'ai une application déployée sur AWS EC2 et utilisant le service AWS RDS. L'application fonctionne mais quand j'essaie d'utiliser la production de console de rails et de rechercher la table d'utilisateur j'obtiens l'erreur suivante: Des idées sur comment je peux résoudre ceci?

ActiveRecord::StatementInvalid: Mysql2::Error: No database selected: SHOW TABLES LIKE 'users'

Ceci est mon database.yml

production: 
    adapter: mysql2 
    encoding: utf8 
    database: <%= ENV['RDS_DB_NAME'] %> 
    username: <%= ENV['RDS_USERNAME'] %> 
    password: <%= ENV['RDS_PASSWORD'] %> 
    host: <%= ENV['RDS_HOSTNAME'] %> 
    port: <%= ENV['RDS_PORT'] %> 

A partir du terminal J'utilise ces commandes:

% bundle exec rails console production 
Loading production environment (Rails 3.2.13) 
1.9.3-p374 :001 > User.all 

Answer 1

On dirait que certaines de ces variables env sont vides. Essayez d'exécuter chacun dans la console seul.
