Description:

Generator for setting up another database in Rails
Just What We were missing

Example:

rails g database NAME adapter:adapter_name db:database_name login:username psswd:password host:host_name port:port_number

NAME 
  name your database here (also applies on directory names and so on ...)

adapter
  for now it supports:
    * MySQL (as 'mysql')
    * PostgreSQL (as 'pg')
    * SQLite (as 'sqlite')

db  
  you can change the name of your database othervise it falls back to the NAME of your db (in most cases leave blank :) )

login
  except sqlite, you can specify your DB credentials (this one stand for username)

psswd
  except sqlite, you can specify your DB credentials (this one stands for password)

host
  except sqlite, you can specify your DB credentials (this one stands for host, in most cases localhost)

port
  except sqlite, you can specify your DB credentials (this one stands for port, in case of postgresql 5432)

This will create:
  config      config/database_store.yml
  directory   db_store
  file        db_store/.keep
  directory   db_store/migrate
  file        db_store/migrate/.keep
  directory   app/models/store
  seeds       db_store/seeds.rb
  rake_task   lib/tasks/database_store.rake
  base_model  app/models/store/base.rb
