django 1.10 中的自定义设置和 wsgi 给我错误

Question

我在自定义设置中遇到这个错误运行连接服务器：

 salahaddin@TulipanROG  ~/Proyectos/tiempoturco/tiempoturco  (tiempoturco)  ./manage.py runserver                                                                                                                                            ✓  640  23:22:06

我有这个文件夹结构：

这是我的 wsgi 代码：

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "tiempoturco.settings.dev")

application = get_wsgi_application()

还有我的 manage.py 代码：

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "tiempoturco.settings.dev")
    try:
        from django.core.management import execute_from_command_line
    except ImportError:
        # The above import may fail for some other reason. Ensure that the
        # issue is really that Django is missing to avoid masking other
        # exceptions on Python 2.
        try:
            import django
        except ImportError:
            raise ImportError(
                "Couldn't import Django. Are you sure it's installed and "
                "available on your PYTHONPATH environment variable? Did you "
                "forget to activate a virtual environment?"
            )
        raise
    execute_from_command_line(sys.argv)

怎么了？我可以执行迁移并创建超级用户，使用 shell plus 和其他命令，但我可以运行服务器。我尝试将设置值更改为 production 和 dev，将这些值放入 __init__.py 并做其他事情但什么也没做。

和middleware_clases：

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.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

我找不到相关信息，我正在测试 django 1.10。

我对 django 1.9.7 没有任何问题，我不知道为什么。同样，当我使用 wagtail 1.6 创建项目时，我在运行服务器中没有问题，wagtail 1.6 安装 django 1.9.7，但我将其替换为 django 1.10 然后在运行迁移后尝试运行项目并创建一个超级用户，当我在浏览器中进入主页时，我可以看到该页面，也可以看到管理员。

所以，我没有使用其他应用程序的问题，但我自己手动创建多个设置给我这个错误。

谁能帮帮我？

Answer 1

尝试更改 MIDDLEWARE_CLASSES

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',
]

Answer 2

我在将我的应用程序升级到 Django 1.10 时遇到了类似的问题。首先，我会尝试将 MIDDLEWARE_CLASSES 更改为 MIDDLEWARE，因为在 Django 1.10 中，他们在这里引入了一种新的中间件样式：

https://docs.djangoproject.com/en/1.10/releases/1.10/

如果这不起作用，我建议检查你的 django 中间件文件，我必须将所有接受对象的类更改为 MiddlewareMixin，你可以通过调用导入：

from django.utils.deprecation import MiddlewareMixin

在我的例子中我改变了

class SiteMiddleware(object):
...

到

from django.utils.deprecation import MiddlewareMixin

class SiteMiddleware(MiddlewareMixin):
...

Answer 3

我要补充一点，除了 mol 提到的内容之外，在升级 Django 的过程中，我不得不暂时禁用链接的虚拟主机。也尝试全新升级到 Django 1.10（卸载 Django 1.9，然后安装 Django 1.10）。

您可能还需要另外清除所有 Django 会话。

Answer 4

我直接在Django 1.10试过了！最初它显示 "TypeError: object() takes no parameters" 错误。在我的 settings.py 中将 MIDDLEWARE 更改为 MIDDLEWARE_CLASSES 后，它起作用了！
