You’ve set the @count variable in the index method. Is it set in your add_to_cart method as well? Perhaps you could extract that into a before_filter to set @count for you. Something like this may get you started
before_fitler :set_visits
def index
increment_count
set_visits
end
private
def increment_count
session[:counter] ||= 0
session[:counter] += 1
end
def set_visits
@count = session[:counter]
end
