Registry::Rails

A container for storing objects and values in the application as long as the request lives. Registry implements ruby's Singleton module, the same object is always available throughout your application.

Installation

Add this line to your application's Gemfile:

gem "registry-rails"

And then execute:

$ bundle

Or install it yourself as:

$ gem install registry-rails

Usage

Set objects and values that you want to retrieve later.

register = Registry::Rails::Register.instance
register.set(:foo, "bar")
register.set(:colors, ["green", "white", "blue"])

You can get a default value if the key doesn't exist, or if you want that isn't nil.

register = Registry::Rails::Register.instance
register.get(:foo) #=> "bar"
register.get(:colors) #=> ["green", "white", "blue"]
register.get(:baz, "default_value") #=> "default_value"

The original issue was: How to get the current_user data inside a model?, so I ended up with this gem, so, now, the example.

class ApplicationController < ActionController::Base
  before_filter :set_current_user

  def set_current_user
    register = Registry::Rails::Register.instance
    register.set(:current_user, current_user)
  end
end

class Foo < ActiveRecord::Base
  def self.do_something(options = {})
    register = Registry::Rails::Register.instance
    current_user_data = register.get(:current_user)
  end
end
