Django_Hosts導入錯誤

Question

我想要做的是使網站重定向到www（如 「example.com 」到「 www.example.com」）

我用PIP到安裝django_hosts，然後跟着文檔網站

下面就爲我的settings.py文件：

"""

Generated by 'django-admin startproject' using Django 1.9.

這是我hosts.py文件：

from django.conf import settings 
from django_hosts import patterns, host 

host_patterns = patterns('', 
    host(r'www', settings.ROOT_URLCONF, name='www'), 
    #host(r'(\w+)', 'path.to.custom_urls', name='wildcard'), 
) 

當我運行蟒蛇manage.py runserver命令我收到以下錯誤：

django.core。 exceptionsImproperlyConfigured：WSGI應用程序'mysite.wsgi.application'無法加載;錯誤導入模塊：'沒有名爲'django_hosts.middleware.HostsRequestMiddlewaredjango'的模塊; 'django_hosts.middleware'不是包'

我在做什麼錯？？

你錯過了一個逗號：

MIDDLEWARE_CLASSES = [ 
    'django_hosts.middleware.HostsRequestMiddleware', # <----- 
    'django.middleware.security.SecurityMiddleware', 
    'django.contrib.sessions.middleware.SessionMiddleware',

    'django.middleware.csrf.CsrfViewMiddleware', 
    'django.contrib.auth.middleware.AuthenticationMiddleware', 
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware', 
    'django.contrib.messages.middleware.MessageMiddleware', 
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
