Django请求查找以前的引荐来源

问题描述

我将请求传递给模板页面。在django模板中如何传递新页面初始化的最后一页。不需要history.go（-1）我需要使用这个

I am passing the request to the template page.In django template how to pass the last page from which the new page was initialised.Instead of history.go(-1) i need to use this

 {{request.http referer}} ??

 <input type="button" value="Back" /> //onlcick how to call the referrer

推荐答案

信息位于属性，它是 HTTP_REFERER （sic）键，所以我相信您应该可以在模板中访问它：

That piece of information is in the META attribute of the HttpRequest, and it's the HTTP_REFERER (sic) key, so I believe you should be able to access it in the template as:

{{ request.META.HTTP_REFERER }}

在shell中工作：

>>> from django.template import *
>>> t = Template("{{ request.META.HTTP_REFERER }}")
>>> from django.http import HttpRequest
>>> req = HttpRequest()
>>> req.META
{}
>>> req.META['HTTP_REFERER'] = 'google.com'
>>> c = Context({'request': req})
>>> t.render(c)
u'google.com'
