[Rails] Send parameter along with method in before_filter

Hello list,

I have an app that has a very simple authorization scheme. A person can have
many roles and roles can have many people.

In my app, I''d like to do

before_filter :login_required  (since no role name is provided, it accepts
any users with credentials)
before_filter :login_required ("administrator") (only accepts those
with
role administrator)
before_filter :login_required {"administrator", "buyer",
"seller"} (accepts
those with roles admin, buyer, seller)

Now, I know the only way you can achieve this is to use the lambda function,
but to me it looks very ugly. Right now I have multiple before_filter, first
checking if they are logged in, then checking their role, etc.

Is there any other way around this that Im not seeing? I tried to come up
with an answer using sessions, but it got far too complicated.

Any help would be fantastic,

Jin

Jin-

	I have a simple plugin that does thing for you with an easy  
declarative syntax and then it defines all the before filters for  
you. There is a write up here:

Erza,

lovely! I was able to get your acl system running, and its working smooth as
butter now. I wasn''t being DRY in my code and this really cleaned
things up.
Thank you very much,

Jin
