我試圖確保我的 url.com 直接進入登錄頁面，然后正確路由。問題是試圖遵循
url.com -> 應該顯示 login.html，如果用戶沒有登錄，它是從 base.html 擴展的
頁面/urls.py
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
]
認為我需要將這里的路徑更改為 base.html
頁面/視圖.py
from django.shortcuts import render
def index(request):
return render(request,'registration/login.html')
所以這兩個組成了如何從url請求login.html。

覺得最后兩行應該是home。
投資組合/網址.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path("", include("pages.urls")),
path('accounts/', include('django.contrib.auth.urls')),
]
不確定 url 模式需要如何在這里我想使用的是專用頁面應用程式中的 django.contrib.auth.urls。
目前只有 url.com/accounts/login 有效，而 url.com 的登錄錯誤，什么也不做。基本檔案

uj5u.com熱心網友回復：
您可以使用@login_required裝飾器，如果用戶未通過身份驗證，它會將用戶重定向到登錄頁面。
from django.contrib.auth.decorators import login_required.
@login_required
def index(request):
# now the index function renders the home page
return render(request,'home.html')
uj5u.com熱心網友回復：
在您的 settings.py 中，您可以輸入以下內容：
LOGIN_URL = '/login/'
以及您希望登錄的任何視圖都可以將其放在相應函式上方的 views.py 中：
@login_required
因此，對于您的索引視圖，您只需要這樣：
from django.shortcuts import render
from django.contrib.auth.decorators import login_required
@login_required
def index(request):
