django - Django - 发生服务器错误。请联系管理员

Question

我刚刚开始学习 Django 并按照他们的教程进行操作。我尝试设置网站三次，每次都遇到相同的错误（在标题中）。

再次，按照他们的官方教程来信。我在教程 2，我应该访问管理页面。当我有时DEBUG = False，我会在标题中收到错误消息，这就是控制台输出的内容：

deusdies@galaksija:~/Documents/djangosites/testing$ python manage.py runserver
Validating models...

这是与DEBUG = False. 有了DEBUG = True，我得到标准的“它有效！” 页面，即使我访问 /admin/ URL 或页面上的任何其他 URL。

这是我的settings.py：

SO 其他地方的一些人建议我创建一个 500.html 模板并查看错误是什么——只是我不知道该怎么做。

在关注了一个较旧版本的 Django 的 YouTube 视频教程后，我找到了解决问题的方法。我不得不取消注释urls.py文件中的某些行（特别是与管理员相关的行），现在它可以工作了。我很困惑为什么在官方教程中忽略了这个......

在控制台中写入：“manage.py syncdb”，它应该可以工作。它对我有用

尝试：

python manage.py migrate
