Hi,

I’ve a session data that is generated when a user logs in.  
I’m trying to access that session data, in before\_filter, in a different  
controller for passing parameter to the before\_filter function.

before\_filter :only =\> [:index] do |obj|  
user = session[:user]  
has\_permission\_in\_any(user.id,component\_id,permission\_id,user.communities)  
end

But i’m not able to do that. What might be the reason?

One more thing,  
I’m not able to call params[],redirect,or anything inside before\_filter.  
Could anyone help? Thanks
