Expected

        <%= form_tag autoscaler_path(@conn, :create), method: :post %>
          Enabled?: <input name="enable" type="checkbox" <%= if @autoscaling_enabled, do: "checked" %> />
          Scale to: <input name="autoscale_target" type="text" value="<%= @autoscale_target %>" />
          <input type="submit" value="Change" />
        </form>
