rails_current

track current_user et all in a tidy, global, and thread-safe fashion.

most rails apps scatter a bunch of @current_foobar vars everywhere. don't do that. it's fugly. instead, do this.

declare the current_XXX variables you'll want tracked. you can pass a block for lazy computation

class ApplicationController

  Current(:user){ User.find session[:current_user }
  Current(:account)

end

you can now access the current state two ways

• globally from anywhere in your code base

  if Current.user
  
    ...
  
  end
  
  Current.user = User.find(id)
  

• using the current_ methods that are added by including the Current module into any class (ActionController::Base and ActionView::Base automatically include it)

  if current_user
  
    ...
  
  end
  
  self.current_user = User.find(id)
  

the Current module is cleared out before every request and is thread safe.

gem install rails_current


gem 'rails-current', :require => 'current'

bundle install
