Python：Django TypeError：object（）不帶參數

Question

我正在將一個django應用程序從1.x移植到2.1，並且遇到了錯誤，即“TypeError：object（）不帶參數”。 我試圖解決這個問題很長一段時間，但即使經過數天的調試和在線搜索，也沒有得到任何線索

已安裝的應用：

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',
]

中間件設置：

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',
]

壓痕沒有問題，

芹菜版：4.2.1
烏鴉版：6.9.0
django版本：2.1

這是我的wsgi.py

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())

以下是錯誤日志的摘錄

File "/usr/lib/python3.5/importlib/__init__.py", line 126, in import_module
        return _bootstrap._gcd_import(name[level:], package, level)

        return WSGIHandler()   
File "/usr/local/lib/python3.5/dist-packages/django/core/handlers/wsgi.py", line 136, in __init__
        self.load_middleware()   
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

使用CustomSentry后出錯：

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/wsgi.py", line 136, in __init__
    self.load_middleware()
  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

我試圖使用ExceptionMiddleware捕獲異常，現在我收到以下錯誤：

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'

任何幫助，將不勝感激。

Answer 1

該錯誤表明您的中間件列表中有舊式中間件。 舊式中間件在實例化時沒有收到論據，而新式中間件則收到處理程序。

現在，根據您的設置，唯一的非Django中間件是whitenoise，但是你說這個錯誤在評論之后仍然存在。

這里有一些建議可以幫助你弄清楚發生了什么：

• 正如我所評論的那樣，向Django源添加斷點或print語句以找出導致問題的中間件。

• 確保您正在編輯的設置文件是實際使用的設置文件。

• 使用Python shell檢查MIDDLEWARE設置的實際值：

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

Answer 2

在你的/app/wsgi.py模塊中試試這個，

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())

參考
1. object（）在django 1.10中沒有參數
2. Django異常中間件：TypeError：object（）不帶參數
