NAME
rails_current
DESCRIPTION
track 'current_user' et all in a tidy, global, and thread-safe fashion.
SYNOPSIS
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
1) globally from anywhere in your code base
if Current.user
...
end
Current.user = User.find(id)
2) or 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.
