本文介绍了Django嵌套URL的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
如何在Django中嵌套url调用?例如,如果我有两个定义为
How do I nest url calls in django? For example, if I have two models defined as
class Post(models.Model):
title = models.CharField(max_length=50)
body = models.TextField()
created = models.DateTimeField(auto_now_add=True, editable=False)
def __unicode__(self):
return self.title
@property
def comments(self):
return self.comment_set.all()
class Comment(models.Model):
comment = models.TextField()
post = models.ForeignKey(Post)
created = models.DateTimeField(auto_now_add=True)
带有以下网址文件
根网址
urlpatterns = patterns('',
url(r'^post/', include('post.urls')),
)
发布网址
urlpatterns = patterns('',
url(r'^$', views.PostList.as_view()),
url(r'^(?P<pk>[0-9]+)/$', views.PostDetail.as_view()),
url(r'^(?P<pk>[0-9]+)/comments/$', include('comment.urls')),
)
评论网址
urlpatterns = patterns('',
url(r'^$', CommentList.as_view()),
url(r'^(?P<pk>[0-9]+)/$', CommentDetail.as_view()),
)
但是当我转到/post/2/comments/1时,出现页面未找到错误,指出
But when I go to /post/2/comments/1, I am given a Page not found error stating
Using the URLconf defined in advanced_rest.urls, Django tried these URL patterns, in this order:
^post/ ^$
^post/ ^(?P<pk>[0-9]+)/$
^post/ ^(?P<pk>[0-9]+)/comments/$
The current URL, post/2/comments/1, didn't match any of these.
虽然当我访问/post/2/comments时这不是问题,但是django是否不允许这样的嵌套URL调用?
This is not a problem though when I visit /post/2/comments Is this not allowed by django to have nested URL calls like this?
推荐答案
我认为可能是因为您正在用美元符号 $
完成正则表达式.尝试以下不带美元符号的行:
I think is probably because you're finishing the regex with the dollar sign $
. Try this line without the dollar sign:
...
url(r'^(?P<pk>[0-9]+)/comments/', include('comment.urls')),
...
