It looks like you're relying on params[:category] to persist across pages. That won't happen. You have to store it in the session hash. Then you can write code like:
def view # first visit, user supplies category session[:category] = params[:category] if params[:category]
# any visit, refer to session hash to get category value getView(session[:category]) end
Hope this solves your problem.
