Nos crea por default en la carpeta config de nuestro proyecto un archivo llamado database.yml el cual contiene algo parecido

CODE:
  1. # SQLite version 3.x
  2. #   gem install sqlite3-ruby (not necessary on OS X Leopard)
  3. development:
  4. adapter: sqlite3
  5. database: db/development.sqlite3
  6. timeout: 5000
  7.  
  8. # Warning: The database defined as "test" will be erased and
  9. # re-generated from your development database when you run "rake".
  10. # Do not set this db to the same as development or production.
  11. test:
  12. adapter: sqlite3
  13. database: db/test.sqlite3
  14. timeout: 5000
  15.  
  16. production:
  17. adapter: sqlite3
  18. database: db/production.sqlite3
  19. timeout: 5000

Este archivo nos indica la configuracion que tomara Rails para acceder a la base de datos, podemos observar que nos hacen la indicacion de que hay que instalar sqlite3-ruby esto lo hacemos con el comando.

CODE:
  1. gem install sqlite3-ruby

Pero si nosotros usamos otra base de datos por ejemplo en mysql, hay que cambiar la configuracion, para poder acceder a mysql y no a sqlite.

CODE:
  1. development:
  2. adapter: mysql
  3. database: recetario
  4. username: root
  5. password: sigmaboy
  6. host: localhost
  7.  
  8. # Warning: The database defined as "test" will be erased and
  9. # re-generated from your development database when you run "rake".
  10. # Do not set this db to the same as development or production.
  11. test:
  12. adapter: mysql
  13. database: recetario
  14. username: root
  15. password: sigmaboy
  16. host: localhost
  17.  
  18. production:
  19. adapter: mysql
  20. database: recetario
  21. username: root
  22. password: sigmaboy
  23. host: localhost

Con esto podemos solucionar el error de
