python - 类型错误 : object() has no parameters using Django-subdomains

Question

我正在尝试使用 django-subdomains 在我的 Django 项目中配置子域应用程序。

这些是我采取的步骤:

• 使用 pip 安装了 django-subdomains。
• 将“subdomains.middleware.SubdomainURLRoutingMiddleware”添加到我的中间件中，只是 b
• 将 SITE_ID 添加到我的设置中，还配置了 SUBDOMAIN_URLCONF

这是我的settings.py

import os

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))


# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/1.10/howto/deployment/checklist/

SECRET_KEY = '*********************************************'

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = True

ALLOWED_HOSTS = []


# Application definition

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    # My application
    'myapp',
]

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',

    # Sub-domains Middleware
    'subdomains.middleware.SubdomainURLRoutingMiddleware',

    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

ROOT_URLCONF = 'mysite.urls'

TEMPLATES = [
    {

                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

WSGI_APPLICATION = 'mysite.wsgi.application'


# Database

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}


# Password validation
# https://docs.djangoproject.com/en/1.10/ref/settings/#auth-password-validators

AUTH_PASSWORD_VALIDATORS = [
    {
        'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
    },

USE_TZ = True


# Static files (CSS, JavaScript, Images)

STATIC_URL = '/static/'


# Sub-domains

SITE_ID = 1

SUBDOMAIN_URLCONF = {
     None: 'mysite.urls',
    'www': 'mysite.urls',
    'blog': 'mysite.urls.blog',
    'shop': 'mysite.urls.shop'
}

我也有这个作为我的mysite.urls.py:

从 django.conf.urls 导入 url，包括从 django.contrib 导入管理员

urlpatterns = [
    url(r'^admin/', admin.site.urls),

    # My application URL
    url(r'^', include('myapp.urls', namespace='myapp'))
]

无论如何，我正在使用这个 View 测试整个事情:

def index(request):
    return HttpResponse(request.subdomain)

当我运行命令 python manage.py runserver 时，出现标题中的错误。我的控制台中的完整回溯可以在这里找到:

我做错了什么？我是否缺少安装步骤？感谢您的帮助!

使用 MIDDLEWARE_CLASSES 而不是 MIDDLEWARE 对我有用。
