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.

• #overload ⇒ Object

  Public: Reload 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/dotenv/rails.rb', line 60

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/dotenv/rails.rb', line 40

def load
  Dotenv.load(*dotenv_files)
end

#overload ⇒ Object

Public: Reload dotenv

Same as load, but will override existing values in ENV

# File 'lib/dotenv/rails.rb', line 47

def overload
  Dotenv.overload(*dotenv_files)
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/dotenv/rails.rb', line 54

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