Module: Russian::RailsIntegration

Defined in:
lib/russian/russian_rails.rb

Overview

Installs Rails-specific patches exposed by the gem.

The integration is lazy: outside Rails it does nothing, and inside Rails it wires itself through ActiveSupport.on_load hooks and also patches framework components that are already loaded.

Устанавливает Rails-специфичные патчи, поставляемые gem'ом.

Интеграция сделана "ленивой": вне Rails она ничего не делает, а внутри Rails подключается через ActiveSupport.on_load и дополнительно патчит уже загруженные части фреймворка.

Examples:

require "russian"
Russian::RailsIntegration.install!

def define_railtie!
  return unless defined?(Rails::Railtie)
  return if defined?(Russian::Railtie)

  Russian.const_set(:Railtie, Class.new(Rails::Railtie) do
    initializer "russian.install" do
      Russian::RailsIntegration.install!
    end
  end)
end

.install! ⇒ void

This method returns an undefined value.

Installs Rails hooks and applies patches to already loaded components.

The method is idempotent and safe to call more than once.

Устанавливает Rails-хуки и применяет патчи к уже загруженным компонентам.

Метод идемпотентен и безопасен для повторных вызовов.

Examples:

Russian::RailsIntegration.install!
