Pass object to a before_filter

Rails
1

i would like to build a authetication system where i can pass a object
(precisely the current id in the controller) to the
before_filter.
then i do some reflection fun to find out if the passed user has that
object.
can that be done? precisely: can i pass a object to a before filter?

thanks
y

ps. is there any plugin or other interesting concept for ACLs?

hm, first when you find someone user… like in application.rb
controller…
before_filter :find_user
def find_user
…
@user = someone
end
You will have @user for all of controllers/views
This mean you will be able to access/change @user instance from any
ctrl/action
so in some_controller.rb like that :
before_filter :do_something
def do_something
if @user.name == “alexey” do { … }
end
