When hitting the `index` action at `/places.json` I'm always getting a `200` and the expected JSON. But hitting the `map` action at `/places/map.json` always gives `304`.

304-problem.rb

# config/routes.rb

    resources :places, only: [:index, :edit, :update], constraints: {format: :json} do
      collection do
        get 'map'
      end


# app/controllers/places_controller.rb

  def index
    @all_places = current_user.places.with_location.certain_or_been_to
  end

  def map
    @weeks_places = current_user.places.with_location.certain_or_been_to.visited_in week_range
  end


# app/models/places.rb

  scope :with_location, where('places.latitude != 0 AND places.longitude !=0')
  scope :certain_or_been_to, where('places.certain = 1 OR place_events_count > 0')
  scope :visited_in, lambda { |range| joins(:place_events).where(place_events: { start_time: range }).uniq }

# app/views/places/index.rabl

node do
  { name: current_user.first_name,
    visited_number: @all_places.size,
    visited_period: Time.now - current_user.created_at,
    time_zone: Time.zone.to_s, time_zone_offset: Time.zone.formatted_offset  }
end
