I have a problem with a function, I tried to achieve a layout switching according to the user level that's logged in (session[:user_level] ) the function looks like this

def switch_layout     case session[:user_level].to_i       when 3 : render :layout=> 'admin'       when nil : render :layout=> 'application'     else render :layout=> 'nonadmin'     end   end

The problem that i have when i use a function like list which uses a variable @users = User.find(:all)

You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.each

In the view there is

<% for user in @users -%>

I don't know why this is happening ... Any ideas?

OK I remembered why I used 'render :layout', the problem was that before_filter didn't worked when i called 'layout' inside of it... now i made just layout :switch_layout. Thanks for the reply.
