Python:Django TypeError:object()不接受任何参数

python-3.5 django-rest-framework python-3.x django python

我正在将一个django应用程序从1.x移植到2.1,遇到了一个错误:“TypeError:object()不带参数”。我试图解决这个问题已经有一段时间了,但即使在网上调试和搜索了好几天之后,我仍然没有得到任何线索

已安装的应用程序:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'allauth',
    'allauth.account',
    'allauth.socialaccount',
    'allauth.socialaccount.providers.github',
    'timezone_field',
    'axes',
    'humans',
    'boxes',
    'pages',
]

中间件设置:

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

压痕没有问题,

raven版本:6.9.0
django版本:2.1

import os
from raven.contrib.django.raven_compat.middleware.wsgi import Sentry

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings")
application=Sentry(get_wsgi_application())

下面是错误日志的摘录

File "/usr/local/lib/python3.5/dist-packages/django/core/handlers/base.py", line 36, in load_middleware
        mw_instance = middleware(handler)
TypeError: object() takes no parameters

in <module>
    application = CustomSentry(get_wsgi_application())
  File "/usr/local/lib/python3.5/dist-packages/django/core/wsgi.py", line 13, in get_wsgi_application
    return WSGIHandler()

  File "/usr/local/lib/python3.5/dist-packages/django/core/handlers/base.py", line 36, in load_middleware
    mw_instance = middleware(handler)
TypeError: object() takes no parameters

我尝试使用ExceptionMiddleware捕获异常,现在出现以下错误:

application = CustomSentry(get_wsgi_application())
File "/usr/local/lib/python3.5/dist-packages/django/utils/deprecation.py", line 85, in __init__
    super().__init__()
TypeError: __init__() missing 1 required positional argument: 'application'

该错误表示您的中间件列表中有一个旧式中间件。旧式中间件在实例化时不接收参数,而新式中间件接收处理程序。

现在,根据您的设置,唯一的非Django中间件是whitenoise,但是您说即使在注释掉它之后错误仍然存在。

如前所述,在Django源代码中添加一个断点或print语句,以找出导致问题的中间件。
确保正在编辑的设置文件是实际使用的文件。

使用pythonshell检查 MIDDLEWARE 设置:

$ python manage.py shell
>>> from django.conf import settings
>>> settings.MIDDLEWARE
...

/app/wsgi.py 模块,

import os
from raven.contrib.django.raven_compat.middleware.wsgi import Sentry

from django.core.wsgi import get_wsgi_application
from django.utils.deprecation import MiddlewareMixin


class CustomSentry(MiddlewareMixin, Sentry):
    pass


os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings")
application = CustomSentry(get_wsgi_application())
