我在django中很新......但我遵循了这个教程：https://docs.djangoproject.com/en/1.9/ref/contrib/admin/

我没有任何自定义AdminSites和自定义AdminModels。

我已经在谷歌上搜索过这个问题，但我仍无法以任何方式解决这个问题。你能帮忙吗？

这是我的settings.py：

Answer 1

要解决此问题，请转到settings.py，其中有新式MIDDLEWARE（在Django 1.10中引入）

将其更改为旧式MIDDLEWARE_CLASSES

the Android documentation for AttributeSet

Answer 2

我找到了答案。变量名称：

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

MIDDLEWARE是Django 1.10中引入的新式配置。将名称更改为MIDDLEWARE_CLASSES，现在可以使用。

现在代码是：

MIDDLEWARE_CLASSES = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

Answer 3

如果有人在使用Django 2.0时出现此问题，则以下配置为新式MIDDLEWARE的配置似乎有效（docs here）：

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

Answer 4

如果任何人在django 2.0.2或更高版本中遇到同样的问题，

只需更新

MIDDLEWARE_CLASSES = (
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'django.middleware.security.SecurityMiddleware',
)

带

MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

它对我有用，因为我创建了我的项目 django 1.0.x但后来更新为django 2.0.2

Answer 5

您不应将MIDDLEWARE更改为MIDDLEWARE_CLASSES。这里发生的事情更有可能是您使用django 1.10创建了应用程序，现在您使用1.9或以前的版本运行它。

确保使用特定版本的django（和所有其他库），以便在不同的计算机上部署或运行时，项目不会中断。

如果您有稳定的代码库，只需运行：

pip freeze > requirements.txt

然后在部署或设置新环境时，请执行以下操作：

pip install -r requirements.txt

您应该始终考虑使用库的固定版本（并希望虚拟环境），并在升级依赖项时测试每个版本的更改。

Answer 6

我的解决方案是我的Django ver。是1.9我重新安装回1.10而没有将MIDDLEWARE更改为MIDDLEWARE_CLASSES。

Answer 7

简单.....

如果您从其他地方选择了代码（意味着项目没有在您的电脑上创建）......那么在您的代码中设置文件时它们可能是MIDDLEWARE的不同配置......所以你需要只需要将你的django生成的MIDDLLEWARE替换掉（创建一个一次性项目 - >转到设置文件---＆gt;复制MIDDLEWARE部分并将其粘贴到你收到错误的项目中）。

Answer 8

我的生产服务器出现了类似的错误，感谢哨兵的面包屑，我发现提出的错误与我的设置有关，尤其是ALLOWED_HOSTS。

使用python 2.7的Django版本1.10.8。

我以前的设置：

ALLOWED_HOSTS = ['0.0.0.0',
                 'beta.mydomain.co.uk',
                 'mydomain.co.uk',
                 'www.mydomain.co.uk',
                 'alpha.mydomain.co.uk']

Sentry面包屑屏幕截图：

之后我环顾四周发现了这个：

以句点开头的值可以用作子域通配符： '.example.com'将匹配example.com，www.example.com和其他任何内容 example.com的子域名。

链接到Django official docs

所以我的最终设置解决了我的问题：

ALLOWED_HOSTS = ['0.0.0.0',
                 'mydomain.co.uk',
                 'www.mydomain.co.uk',
                 '.mydomain.co.uk']

希望这很有用：）
