Django:是否根据URL在settings.py中动态设置SITE_ID?

问题描述

有什么好方法可以根据URL中的域名在settings.py中动态设置SITE_ID?

What is a good way to dynamically set SITE_ID in settings.py based on domain name in URL?

我有一个应用程序将使用太多的域名(基于城市)运行，每个域名都无法使用自定义settings.py文件.

I have an app that will be running with too many domain names (city based) that a custom settings.py file for each domain is just not doable.

有没有办法动态设置它?

Is there a way to set it dynamically?

推荐答案

您可以执行一个自定义中间件，该中间件读取请求并设置SITE_ID.我在我的一个网站上使用此代码:

You can do a custom middleware which reads the request and sets the SITE_ID. I use this code on one of my sites:

class SiteMiddleware(object):
    def process_request(self, request):
        try:
            current_site = Site.objects.get(domain=request.get_host())
        except Site.DoesNotExist:
            current_site = Site.objects.get(id=settings.DEFAULT_SITE_ID)

        request.current_site = current_site
        settings.SITE_ID = current_site.id

您应该查看中间件的Django文档，以了解如何添加自己的中间件. https://docs.djangoproject.com/en/dev/topics/http/middleware/

You should look at Django's documentation on middleware to find out how to add your own middleware. https://docs.djangoproject.com/en/dev/topics/http/middleware/
