Я дословно следил за Django учебником для начинающих, создавая проект под названием 'Pages' , когда внезапно мой компьютер выдал мне ошибку ( AttributeError ) когда я пытался получить доступ к странице localhost (http://127.0.0.1: 8000 / ), которая должна была сказать «Hello World». Вместо того, чтобы видеть утверждение, там была страница «Этот сайт недоступен» . Я совершенно не понимаю, почему это произошло, потому что я следил за инструктором слово в слово, но получил другой результат. Если кто-то может помочь, это будет очень признательно!
Вот мои файлы
views.py
from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
def home_view(*args, **kwargs): # args, kwargs
return HttpResponse("<h1>Hello World</h1>") # string of HTML code
URL. py
"""trydjango URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path
from pages import views
urlpatterns = [
path('', views.home_view, name='home'),
path('admin/', admin.site.urls),
]
Сообщение об ошибке
AttributeError: module 'pages.views' has no attribute 'home_view'
