一旦我更改DEBUG = False,我的站点将生成500(使用wsgi & manage.py runserver),并且在Apache错误日志中没有错误信息,当我将DEBUG更改为True时,它将正常运行。

我使用的是Django 1.5和Python 2.7.3 这是Apache访问日志和Apache错误日志中没有任何日志

当前回答

我遇到了这个问题。结果发现,我在模板中使用静态模板标记包含了一个不再存在的文件。看了一下日志,我发现了问题。

我想这只是造成这种错误的众多可能原因之一。

这个故事的寓意是:总是记录错误,总是检查日志。

其他回答

我开始以debug=False的形式得到500

django.urls.exceptions.NoReverseMatch: Reverse for 'home' not found.
or...
django.urls.exceptions.NoReverseMatch: Reverse for 'about' not found.

当引发django.core.exceptions.ValidationError而不是引发rest_framework.serializer . validationerror时

公平地说,它之前已经引发了一个500,但作为一个ValidationError, debug=False,这变成了NoReverseMatch。

Django 1.5引入了允许的主机设置,这是出于安全原因所必需的。用Django 1.5创建的设置文件中有这样一个新部分,你需要添加:

# Hosts/domain names that are valid for this site; required if DEBUG is False
# See https://docs.djangoproject.com/en/1.9/ref/settings/#allowed-hosts
ALLOWED_HOSTS = []

在这里添加您的主机,如['www.beta800.net']或['*']用于快速测试,但不要在生产中使用['*']。

补充主要答案 在开发和生产之间切换时,在settings.py中更改ALLOWED_HOSTS和DEBUG全局常量是很烦人的。 我使用这段代码来自动设置这些设置:

import socket

if socket.gethostname() == "server_name":
    DEBUG = False
    ALLOWED_HOSTS = [".your_domain_name.com",]
    ...
else:
    DEBUG = True
    ALLOWED_HOSTS = ["localhost", "127.0.0.1",]
    ...

如果你使用macOS,你可以写一个更通用的代码:

if socket.gethostname().endswith(".local"): # True in your local computer
    DEBUG = True
    ALLOWED_HOSTS = ["localhost", "127.0.0.1",]
else:
    ...

这可能会帮助其他人,在我的情况下,丢失图标的问题。

我也遇到过类似的问题,我将报告我是如何解决我的问题的,因为可能有人也有同样的经历。

在我的例子中,错误是因为服务器没有从主页中找到一些静态文件而引起的。

因此,请确保错误只发生在索引中或发生在另一个页面上。如果问题只发生在索引中,很可能你需要检查静态文件。我建议打开Chrome预览控制台,检查是否有任何错误。

在我的例子中,服务器无法找到favicon.ico和其他两个CSS。

为了解决这个问题,我传递了python manage.py collectstatic,它起作用了。
