Django 中间件不工作模板

Question

我为动态徽标、站点标题等实现了 Django 中间件。它运行非常缓慢。例子。当我更新我的网站标题时，它并没有立即更新。但是当我重新启动服务器时它正在工作。这是我的代码


class AppBasicInfo():
    def __init__(self, get_response):
        self.site = SiteInfo.objects.first() if SiteInfo.objects.first() else "Not Implemented"
        self.get_response = get_response

    def __call__(self, request, *args, **kwargs):
        request.site = self.site
        response = self.get_response(request)
        return response

设置文件

MIDDLEWARE = [
    'blog.middleware.AppBasicInfo',
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'debug_toolbar.middleware.DebugToolbarMiddleware',

    'blog.middleware.AppMenu',
    'blog.middleware.SocialIcon',
    'blog.middleware.DynamicYear',

]

我调用中间件变量作为我的模板，如 {{request.site.site_title}}

Answer 1

__init__只调用了一次，试试移动

self.site = SiteInfo.objects.first() if SiteInfo.objects.first() else "Not Implemented"

到__call__
