Question

我从以下网站完成了所有步骤： https://tutorial-extensions.djangogirls.org/en/homework_create_more_models/

一切似乎都是正确的，并且由于某种原因服务器无法在cmd上运行。

下面是显示的错误：

32\Scripts\mysite\urls.py", line 26, in <module>
    path('post/<int:pk>/comment/', views.add_comment_to_post, name='add_comment_to_post'),
AttributeError: module 'django.contrib.auth.views' has no attribute 'add_comment_to_post'

多次编辑urls.py，views.py，forms.py，并且还通过以下方式将注释模型添加到了数据库中：“ python manage.py makemigrations博客”和“ python manage.py migrate博客” < / p>

urls.py:

from django.contrib import admin
from django.urls import path, include
from django.contrib.auth import views


urlpatterns = [
    path('admin/', admin.site.urls),
    path('accounts/login/', views.LoginView.as_view(), name='login'),
    path('accounts/logout/', views.LogoutView.as_view(next_page='/'), name='logout'),
    path('', include('blog.urls')),
    path('post/<int:pk>/comment/', views.add_comment_to_post, name='add_comment_to_post'),
    path('comment/<int:pk>/approve/', views.comment_approve, name='comment_approve'),

Answer 1

您已将网址格式放在错误的urls.py中；您已将它们放在mysite / urls.py中，说明说要使用blog / urls.py。

AttributeError：模块“ django.contrib.auth.views”没有属性“ add_comment_to_post”
