NoReverseMatch Django，get_success_url在CreateView

Question

我在我的博客應用程序中創建一個創建視圖來創建一個帖子。在 創建視圖我使用了函數get_success_url。我希望當我創建 的帖子時，它會重定向到blog_post_list。^h

我得到的錯誤：NoReverseMatch

我猜它做某事與URL模式。

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), 

    ] 

網址博客應用在blogapp

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'), 
] 

意見

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

您還沒有命名空間，所以它不是能夠找到blog_post_list

所以只需在反向呼叫中添加命名空間

reverse("posts:blog_post_list")
