我使用 haystack 搜索我的 django 网站，它完美地做到了这一点。但是在我的结果页面上，链接不起作用。在我的模板中，我正在使用代码：

<a href="{{ result.object.get_absolute_url }}">{{ result.object.title }}</a>

在我的 other/models.py 中，我包括：

def get_absolute_url(self):
    return urlresolvers.reverse('post', args=[self.pk])

我的 urls.py 看起来像：

from django.conf.urls.defaults import *
from dbe.other.models import *

urlpatterns = patterns('dbe.other.views',
(r"^(\d+)/$", "post"),
(r"^add_comment/(\d+)/$", "add_comment"),
(r"^delete_comment/(\d+)/$", "delete_comment"),
(r"^delete_comment/(\d+)/(\d+)/$", "delete_comment"),
(r"^month/(\d+)/(\d+)/$", "month"),
(r"", "main"),
)

它应该链接到的 URL 是：

http://127.0.0.1:8000/other/10/

但它仍然链接到：

http://127.0.0.1:8000/search/?q=searchterm

在外壳中会发生这种情况：

>>> from other.models import Post
>>> inst = Post.objects.get(pk=1)
>>> inst.get_absolute_url()
Traceback (most recent call last):
File "<console>", line 1, in <module>

"arguments '%s' not found." % (lookup_view_s, args, kwargs))

您应该在模型中定义 get_absolute_url() 方法。

例如：

from django.core import urlresolvers

class Widget(models.Model):
    # fields ...
    def get_absolute_url(self):
        return urlresolvers.reverse('widget_detail', args=[self.pk])

这假设小部件详细视图的 url 名称是：'widget_detail'
