Caching of roles

[vitalyny]

Hey,

I implemented authentication with Authlogic and authorization with
Acl9. Now I'm trying to avoid multiple hits to database to check if
user is admin by keeping this in the session.

What I thought is that this code should work:

class ApplicationController < ActionController::Base
...
helper_method :current_user_session, :current_user, :is_admin
...

private
def is_admin
return current_user_session[:is_admin] if defined?
(current_user_session[:is_admin])
current_user_session[:is_admin] = current_user.has_role?
(:admin)
end

So basically on a first call to is_admin helper method, it should add
a boolean value to session[:is_admin] and then for any other calls,
take it from the session. But I receive this error:

undefined method `[]=' for #<UserSession:
{:unauthorized_record=>"<protected>"}>

And I stuck here. What am I doing wrong?

I think you should use session[:foobar], not current_user_session[:foobar]

That is a great advice! Thank you, Oleg.
