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

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
