require 'active_record' # Change the following to reflect your database settings ActiveRecord::Base.establish_connection( adapter: 'mysql2', # or 'postgresql' or 'sqlite3' or 'oracle_enhanced' host: 'localhost', database: 'your_database', username: 'your_username', password: 'your_password' ) # Define your classes based on the database, as always class SomeClass < ActiveRecord::Base #blah, blah, blah end # Now do stuff with it puts SomeClass.find :all some_class = SomeClass.new
