Python Django网站地图'；邮政'；对象没有属性'；获取绝对url'；？

我正在创建一个简单的django 1.9应用程序，其中包括一个博客，我希望该网站拥有由网站页面和博客文章条目组成的网站地图。到目前为止，我能够构建一个网站地图，将静态页面生成为网站地图，但博客文章网站地图给了我一个错误

“post”对象没有属性“get_absolute\u url

，这是我的有人告诉我哪里出了问题

sitemaps.py

from django.contrib import sitemaps

from django.contrib.sitemaps import Sitemap

from django.core.urlresolvers import reverse

from administration.models import Post


class StaticSitemap(sitemaps.Sitemap):

      changefreq = "daily"

      priority = 1.0



     def items(self):

          return ['administration:index', 'administration:about']



     def location(self, item):
          return reverse(item)



class PostSitemap(Sitemap):

      changefreq = "daily"

      priority = 0.5


      def items(self):
          return Post.objects.all()`

class Post(models.Model):
    STATUS_CHOICES = (('draft', 'Draft'),('published', 'Published'),)

当您使用

Sitemap

类并且自己没有实现

location（）

方法时，默认情况是对每个对象调用

get\u absolute\u url（）

网站上的文件说：

本例中没有location方法，但您可以提供它来指定对象的URL。默认情况下，location（）对每个对象调用get_absolute_url（），并返回结果

---

因此，您应该在

PostSitemap

上实现

location（）

，或者在

Post

模型上实现

get\u absolute\u url（）

。

谢谢您的帮助！添加

get\u absolute\u url

成功了。您是如何为get\u absolute\u url函数编码的？@sly\u Chandan最简单的方法应该返回类似

f”/posts/{self.id}“

，基本上是指向您对象的url路径，或者您可以使用该方法构造它，该方法基于您的url创建它。谢谢您的帮助！添加
