Python 在Django中使用HttpRequest.build_absolute_uri（位置）时出错

我的代码：

from django.http import HttpRequest

admin_subject = "New question added"
admin_message = "A new question has been successfully added. Please review and approve it."
location = reverse("admin:appname_question_change", args=(new_question.pk,))
url = HttpRequest.build_absolute_uri(location)
admin_html_message = "<h3>%s</h3>\
                        <p>%s</p>\
                        <a href='%s'>%s</a>" % (admin_subject, admin_message, url, url)
mail_admins(admin_subject, admin_message, fail_silently=False, connection=None, html_message=admin_html_message)

我尝试了很多，但不知道是什么导致了这个错误。

我希望绝对uri通过电子邮件发送。

我认为您收到的错误非常明确

build\u absolute\u uri

是一个实例方法，因此应该由

HttpRequest

实例调用

>>> from django.http import HttpRequest

>>> request = HttpRequest()
>>> location = reverse("admin:appname_question_change", args=(new_question.pk,))
>>> url = request.build_absolute_uri(location)

>>> from django.http import HttpRequest

>>> request = HttpRequest()
>>> location = reverse("admin:appname_question_change", args=(new_question.pk,))
>>> url = request.build_absolute_uri(location)
