Are you then using the @current_operator variable in places in your
controller? (like "if @current_operator.name == 'fred'..."?)
If so, instead use a helper method to return the operator (and
populate it if necessary), rather than the filter method:
class ApplicationController < ActionController::Base
protect_from_forgery
before_filter RubyCAS::Filter
include SessionsHelper
helper_method :current_operator
def current_operator
@current_operator ||= fetch_operator
end
private
def fetch_operator
session[:cas_user] &&
Operator.find_by_uid(session[:cas_user])
rescue ActiveRecord::RecordNotFound
redirect_to("/404.html")
end
end
