Multiple database connection in Rails

Question

I\'m using active_delegate for multiple connection in Rails. Here I\'m using mysql as master_database for some models,and postgresql for some other models.

Problem i

Answer 1

This will change the database connection for a single model object.

$config = YAML.load_file(File.join(File.dirname(__FILE__),
   '../config/database.yml'))

class ModelWithDifferentConnection < ActiveRecord::Base
  establish_connection $config['connection_name_from_database_yml']
end

If you are using the same server but just a different database file then you can do something like this instead.

class ModelWithDifferentConnection < ActiveRecord::Base

  # Lives in the CURRICULUM database
  def self.table_name
    "database.table"
  end

end
