【问题描述】：
出现错误：
NoReverseMatch：“single_view”与参数“('article', 2013, 12, 12, 'triumphmotorcycleslaunched10newbikesinindia', 16)' 和关键字参数“{}”的反向。尝试了 1 种模式：[u'(P[article|review|blog|news|video])/(P\d{4})/(P\d{2})/(P\d{2} )/(P\w+)/(P\d+)$']
这是我的 URLConf、模型和视图
/urls.py
...
url(r'^(P<post_type>[article|review|blog|news|video])/', include('post.urls', namespace='post_views')),
...
/post/urls.py
urlpatterns = patterns('',
url(r'^$', PostView.as_view(), name="index"),
url(r'^(P<year>\d{4})/(P<month>\d{2})/(P<day>\d{2})/(P<slug>\w+)/(P<post_id>\d+)$', PostView.single, name="single_view")
)
and get_absolute_url in models.Post class
/post/models.py
def get_absolute_url(self):
from django.core.urlresolvers import reverse
return reverse('post_views:single_view', args=['article', 2013, 12, 12, str(self.slug).replace('-', ''), self.id])
并查看
/post/views.py
def single(self, request, post_type, year, month, day, slug, post_id, *args, **kwargs):
post_single = Post.objects.get(pk=1)
context = {
"post_single": post_single,
}
return self.render_to_response(context);
解析器错误：在@Yeo 建议后尝试
from django.core.urlresolvers import reverse, resolve
from post.models import Post
p = Post.objects.get(pk=16)
reverse('post_views:single_view', args=['article', 2013, 12, 12, p.slug, p.id])
resolve('/article/2013/12/12/triumphlaunched10newbikesinindia/16/')
Resolver404: {u'path': u'article/2013/12/12/triumphlaunched10newbikesinindia/16/', u'tried': [[], [ (None:vehicle) ^vehicle/>], [ ( None:post_views) ^(P[article|review|blog|news|video])/>], [ (None:gallery) ^gallery/>], [ (None:author) ^author/>], [.* )$>], [ (None:None) ^admin/doc/>], [ (admin:admin) ^admin/>], [ (None:None) ^admin_tools/>]]}
【问题讨论】：
-
尝试从
args中删除'article'。 -
为了更好地调试 NoReverseMatch，请改为运行 reverse 命令，并使用
resolverResolver Docs 提供完整的 url 来查看正确的格式应该如何，当然在你的 django 中运行它壳。你很快就能回答你自己的问题了 :) 祝你好运 -
@Rohan 仍然无法工作...

@Yeo 我试过
resolve，但这也引发了错误。我试过了：resolve('article/2013/12/12/triumphlaunched10newbikesinindia/16') -
尝试使用前导
/斜线resolve('/article/2013/12/12/triumphlaunched10newbikesinindia/16/')
