数据库不断恢复到以前的日期

Question

所以，我写这篇文章的前提是我很清楚你会询问更多信息，但我还不知道该说什么。

我有一个 django 应用程序，它为个人网站提供动力，它有一个简单的留言板，供人们给我留言，告诉我我有多棒。现在，总的来说，我在使用这个应用程序时遇到了很多麻烦，并且来回经历了很多 git-ness，我猜这可能是导致这个问题的原因。

不知何故，我的数据不断被我的数据库的特定快照替换。今天早上我检查它时，它有十条旧的虚拟测试消息，还有一条新的真实消息。我回复了新的真实的，删除了虚拟测试的，一切看起来都很好。那天我没有再碰过这个应用程序。刚才再去查的时候，新消息不见了，假消息又回来了。

它通过 Heroku 部署并使用 Python 2.7 和 Django 1.6 编写。该网站位于 www.wienerwedding.com/guestbook/。

这是我的 settings.py 文件，这是我对可能存在问题的唯一猜测。 如果你告诉我看什么可能有帮助，我会把它包括在内。

您已将 DEBUG 设置为 True，根据该代码，这意味着您将始终使用可能与您的应用程序一起上传的 sqlite db 文件，而不是 Heroku 的 Postgres 设置。确保 DEBUG 为 false，和/或使用另一个环境变量来确定是否使用开发数据库。
