Question

我正在尝试添加我单独制作的用户应用，然后尝试将其添加到我的博客中。但是问题是每次我尝试添加此内容时，都会出现一些错误，就像我现在收到的此错误一样。

提高NoReverseMatch（msg）   django.urls.exceptions.NoReverseMatch：找不到“登录”的反向。 “登录”不是有效的视图函数或模式名称。

到目前为止，我已经做到了

blog / urls.py

from django.contrib import admin
from django.urls import path, include
from django.conf.urls.static import static
from django.conf import settings
from users.views import login_view, register_view, logout_view

# from users import views as user_views
from posts.views import index,postDetail, categoryDetail, blog, search

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', index, name="home"),
    path('blog/', blog, name="blog"),
    path('search/', search, name='search'),
    path('<slug>/', postDetail, name='post-detail'),
    path('category/<slug>/', categoryDetail, name='category-detail'),
    path('login/', login_view),
    path('logout/', logout_view),

Answer 1

# path('login/', auth_views.LoginView.as_view(template_name='users/login.html'), name='login'),

此网址已被注释掉，您没有其他人使用name="login"。

Answer 2

您尚未给登录URL命名，

path('login/', login_view, name='login'),

提高NoReverseMatch（msg）django.urls.exceptions.NoReverseMatch：为'login
