This is the example contents of the Rakefile, which you would use to run active record tasks without using Rails. It assumes using the same directories as rails uses: `db/migrate`, `config/database.yml`.
require 'bundler/setup'
require 'active_record'
include ActiveRecord::Tasks
db_dir = File.expand_path('../db', __FILE__)
config_dir = File.expand_path('../config', __FILE__)
DatabaseTasks.env = ENV['ENV'] || 'development'
DatabaseTasks.db_dir = db_dir
DatabaseTasks.database_configuration = YAML.load(File.read(File.join(config_dir, 'database.yml')))
DatabaseTasks.migrations_paths = File.join(db_dir, 'migrate')
task :environment do
ActiveRecord::Base.configurations = DatabaseTasks.database_configuration
ActiveRecord::Base.establish_connection DatabaseTasks.env
end
load 'active_record/railties/databases.rake'
