django中零星的TemplateDoesNotExist错误

Question

我在运行Python2.4的服务器上安装了django (v1.1.1)。在我的本地主机/开发计算机上，这个站点运行得很好。当我将文件上传到生产服务器时，它似乎工作得很好，但在页面刷新之后，我收到随机的TemplateDoesNotExist错误。

在跟踪报告中，我查看了TEMPLATE_DIRS变量，以确保我指向了正确的位置，并且每次刷新页面时，它实际上都会发生变化：

TEMPLATE_DIRS

(‘template’，'/var/www/vhosts/mysite.com/apps')

还有这个

TEMPLATE_DIRS

(‘template’，‘/var/www/django-site/apps/template’)

当我刷新页面时，django/python怎么可能在两个不同的位置查找？3-4次尝试后，它突然开始工作，直到我刷新或转到下一页。正确的位置是/var/www/vhosts/mysite.com/apps/templates，这是在我的settings.py文件中定义的：

TEMPLATE_DEBUG = DEBUG

非常感谢你的帮助！

这听起来像是您的apache配置或您正在为web服务器使用的任何东西的问题。PROJECT_ROOT：

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))

依赖于当前的绝对路径，这是由运行应用程序的环境设置的。确保您的web服务器配置中只存在一个用于处理URL的路由。

其次，确保所有django环境都被彻底关闭，您可能会有一些旧的、错误配置的环境来处理请求。
