Question

我在博客应用中创建了一个创建视图来创建帖子。在里面创建视图我使用了函数get_success_url。我想要什么时候创造一篇文章，它将重定向到blog_post_list。 ħ

我收到错误：NoReverseMatch

我想它必须与urlpatterns一起做。

main urls.py

    from django.conf.urls import url, include
    from django.contrib import admin

    from blog.views import AboutPageView, ContactPageView 

    urlpatterns = [
        url(r'', include('blog.urls', namespace='posts')),
        url(r'^blog/', include('blog.urls', namespace='posts')),
        url(r'^about/$', AboutPageView.as_view(), name='about'),
        url(r'^contact/$', ContactPageView.as_view(), name='contact'),


       #admin and login
       url(r'^admin/', admin.site.urls), 

    ]

博客应用中的网址

from django.conf.urls import url

from .views import blog_postListView, blog_postDetailView, blog_postCreateView 

urlpatterns = [
    url(r'^$', blog_postListView.as_view(), name='blog_post_list'),
    url(r'^create/', blog_postCreateView.as_view(), name='blog_post_create'),
    url(r'^(?P<slug>[-\w]+)$', blog_postDetailView.as_view(), name='detail'),
]

在blogapp中的

观点

class blog_postCreateView(CreateView):
    #model = blog_post
    form_class = blog_postForm
    template_name = "form.html"
    #fields = ["title", "content"]
    def get_success_url(self):
        return reverse("blog_post_list")

Answer 1

您尚未包含命名空间，因此无法找到blog_post_list

所以只需在反向调用中添加名称空间

reverse("posts:blog_post_list")

有关NoReverseMatch错误的详细信息，请参阅What is a NoReverseMatch error, and how do I fix it?

NoReverseMatch Django，CreateView中的get_success_url
