Overview

Dotenv Railtie for using Dotenv to load environment from a file into Rails applications

Class Method Summary

• .load ⇒ Object

  Rails uses ‘#method_missing` to delegate all class methods to the instance, which means `Kernel#load` gets called here.

Instance Method Summary

• #load ⇒ Object

  Public: Load dotenv.

• #root ⇒ Object

  Internal: ‘Rails.root` is nil in Rails 4.1 before the application is initialized, so this falls back to the `RAILS_ROOT` environment variable, or the current working directory.

Class Method Details

.load ⇒ Object

Rails uses ‘#method_missing` to delegate all class methods to the instance, which means `Kernel#load` gets called here. We don’t want that.

# File 'lib/envvar/rails.rb', line 41

def self.load
  instance.load
end

Instance Method Details

#load ⇒ Object

Public: Load dotenv

This will get called during the ‘before_configuration` callback, but you can manually call `Dotenv::Railtie.load` if you needed it sooner.

# File 'lib/envvar/rails.rb', line 28

def load
  Envvar.load(config_file, Rails.env)
end

#root ⇒ Object

Internal: ‘Rails.root` is nil in Rails 4.1 before the application is initialized, so this falls back to the `RAILS_ROOT` environment variable, or the current working directory.

# File 'lib/envvar/rails.rb', line 35

def root
  Rails.root || Pathname.new(ENV['RAILS_ROOT'] || Dir.pwd)
end
