Question

这是我的代码

#Send mail to admin
admin_subject = "New question added"
admin_message = "A new question has been successfully added. Please review and approve it."
url = reverse("admin:appname_question_change", args=(new_question.pk,))
admin_html_message = "<h3>%s</h3>\
                                <p>%s</p>\
                                <a href='%s'>%s</a>" % (admin_subject, admin_message, url, url)

我用它来发送邮件。在我收到邮件中的完整URL之前。与http://192.168.1.0:8000/admin/appname/answer/12

一样

但现在只提供/admin/appname/answer/12

之类的路径

我没有改变任何东西只是为其他视图添加了相同的代码。

我的新代码：

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)

仍然收到此错误：

unbound method build_absolute_uri() must be called with HttpRequest instance as first argument (got str instance instead)

Answer 1

Django＆＃39; Request has a method for that：

<强> HttpRequest.build_absolute_uri（位置）   返回位置的绝对URI形式。如果未提供位置，则该位置将设置为request.get_full_path（）。

如果该位置已经是绝对URI，则不会更改。否则，绝对URI是使用此请求中可用的服务器变量构建的。

示例：＆＃34; http://example.com/music/bands/the_beatles/?print=true＆＃34;

传递url来自reverse

更新：除其他外，Django Rest Framework提供了一个可以构建绝对URL的反向版本 - 如果您以前使用它，它将解释更改。（你改变了什么？）

反向网址没有显示django中的完整网址
