Django Bootstrap 旋转木马不会骑

Question

这是我建立网站的第一个项目。我一直在关注这些我想用的tutorials. I browsed through the Bootstrap components page and found a Carousel method (slides only)。我将其复制并粘贴到我的代码中。第一张图片显示正确，因为它处于活动状态，但轮播不会滑动到下一张图片。第一个代码块显示了一个汇总版本。第二段代码在运行python manage.py runserver之后。第三段代码是当我打开IP地址link时。我不确定我做错了什么。有什么建议么？如果您需要更多信息，请告诉我。

您只包含了 bootstrap 中的 css。我相信你也需要javascript。您可能想要添加这些脚本：
