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
