Module: MultiConfig::ORMs::ActiveRecord::ClassMethods

Defined in:
lib/multi_config/orms/active_record.rb

Overview

This ‘acts_as` style extension provides the capabilities for using multiple database configuration files. Any model can specify what database config file to use by using a Rails 3.2 style self.config_file= method.

Example:

class DifferentTable < ActiveRecord::Base
  self.config_file = 'other_db'
end

In config/other_db.yml

development: &development
  database: db/other_db
  host: localhost
  adapter: sqlite3

test:
  <<: *development
