运行 Django 服务器后出现页面 404 错误

Question

I have just started learning django and was trying to make a smartnotes App project by following a course.我刚刚开始学习 django 并试图通过学习课程来制作一个 smartnotes 应用程序项目。 I updated the setting.py file to add website into Instaled_Apps.我更新了 setting.py 文件以将网站添加到 Instaled_Apps。 Then have written a function named home in views.py Finally I added it's entry into urls.py fie "welcome.html is insdie homeApp/templates/home directory" But when I run the server, I am getting following error on webpage:然后在views.py中写了一个名为home的function最后我将它添加到urls.py中fie“welcome.html是insdie homeApp/templates/home目录”但是当我运行服务器时，我在网页上收到以下错误：

views.py视图.py

from django.shortcuts import render
from django.http import HttpResponse
from django.http import HttpRequest


# Create your views here.

def home(request):
    return render(request, 'home/welcome.html', {})

settings.py设置.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # apps that I created
    'home',
]

urls.py网址.py

from django.contrib import admin
from django.urls import path
from django.urls import path
from home import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('home', views.home),
]

welcome.html欢迎。html

Answer 1

Look at your urlpatterns :看看你的urlpatterns ：

urlpatterns = [
    path('admin/', admin.site.urls),
    path('home', views.home),
]

You haven't set the path for real "home" page, which should be "" .您还没有设置真正的“主页”页面的路径，应该是"" 。 Change it to:将其更改为：

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', views.home),
]

And you will be fine.你会没事的。 The first argument in parenthesis is real "value" that you need to provide just after the domain ( http://localhost:8000/ with local service).括号中的第一个参数是您需要在域之后提供的真实“值”（ http://localhost:8000/与本地服务）。
