Class Method Details

.connect ⇒ Object

Connect to the database using ActiveRecord’s default behavior

# File 'lib/earth.rb', line 72

def Earth.connect
  ActiveRecord::Base.establish_connection
  ActiveRecord::Base.connection
end

.env ⇒ Object

The current environment. Earth detects the following environment variables:

  • EARTH_ENV (for CLI apps and daemons)

  • RAILS_ENV

  • RACK_ENV

Default is ‘development`

# File 'lib/earth.rb', line 84

def Earth.env
  @env ||= ActiveSupport::StringInquirer.new(ENV['EARTH_ENV'] || ENV['RAILS_ENV'] || ENV['RACK_ENV'] || 'development')
end

.init(*args) ⇒ Object

Earth.init is the gateway to using Earth. It can load all models at once, connect to the database using Rails conventions, and set up the models to pull data from original sources instead of Brighter Planet’s pre-processed data service.

  • :mine_original_sources, if true, will load files necessary to data mine from scratch rather than downloading from data.brighterplanet.com. Note that you must run Earth.init before requiring models in order for this option to work properly.

  • :connect will connect to the database for you

Parameters:

  • load_directive (Symbol) —

    use ‘:all` to load all models at once (optional)

  • options (Hash) —

    load options
