是否可以将Django Sites Framework与同一实例上的多个Sites一起使用? [英] Is it possible to use the Django Sites Framework with multiple Sites on the same instance?

问题描述

我已经定义了多个站点，作为网站框架建议的文档.

I have defined multiple sites as the documentation of the Site Framework suggested.

我知道，如果我要运行应用程序的多个实例，并且每个实例具有不同的设置文件(不同的SITE_ID)，则Django总是会知道要使用哪个网站.

I understand that if I would run mulitple instances of my application with each of them having a different settings file (different SITE_ID), Django would always know which Site to use.

我试图做的是运行一个实例，其中有多个站点可用，应根据站点的当前URL选择正确的站点.

What I was trying to do is to run a single instance, where multiple sites are available, and the right Site should be chosen depending on the current url of the site.

网站文档状态:

SITE_ID设置指定站点对象的数据库ID与该特定设置文件相关联.如果设置是省略，get_current_site()函数将尝试通过将域名与主机名进行比较来获取当前站点.request.get_host()方法.

The SITE_ID setting specifies the database ID of the Site object associated with that particular settings file. If the setting is omitted, the get_current_site() function will try to get the current site by comparing the domain with the host name from the request.get_host() method.

因此，我尝试从我的settings.py中删除SITE_ID，并希望Django如上所述检查域以找到当前站点，但是由于以下异常而失败:

So I tried to remove the SITE_ID from my settings.py and was hoping that Django would check the domain to find the current Site as stated above, howewer this fails with the following exception:

You're using the Django "sites framework" without having set the SITE_ID setting. Create a site in your database and set the SITE_ID setting or pass a request to Site.objects.get_current() to fix this error.

因此，尽管文档中提出了其他建议，但此设置似乎不可忽略

So it seems like although the documentation suggests otherwise, this setting is not ommitable

我知道，当没有可用的Request对象来查找当前Site时，使用这样的Sites Framework会导致问题，但是在我的应用程序上下文中这应该不是问题.

I understand that using the Sites Framework like this would lead to problems when there is no Request object available to find the current Site, but this should not be a problem in the context of my application.

是否可以通过仅检查应用程序的当前域而无需在设置文件中对SITE_ID进行硬编码的情况下使用Sites Framework?

Is it possible to use the Sites Framework without hard-coding the SITE_ID in the settings file by just checking the current domain of the application?

我正在将Django 1.9.9与Python 3.4.3结合使用

推荐答案

要检查当前域"，您需要有一个请求-如错误消息中明确提到的那样:

To "check the current domain" you need to have a request - as clearly mentionned in the error message :

或将请求传递到Site.objects.get_current()

or pass a request to Site.objects.get_current()

否则代码将如何知道当前域"?

Else how would the code know the "current domain" ?
