AttributeError: module 'pages.views' has no attribute 'home_view'

Question

I was following a beginner's Django tutorial word-for-word creating a project called 'Pages' when all of a sudden my computer gave me an error (AttributeError) when I tried to access the localhost page (http://127.0.0.1:8000/) that was supposed to say 'Hello World.' Instead of seeing the statement, a 'This site can’t be reached' page was there. I am completely confused as to why this happened because I was following the instructor word-for-word yet got a different result. If anyone can help that would be very much appreciated!

Here are my files

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

urls.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),
]

Error message

AttributeError: module 'pages.views' has no attribute 'home_view'

Answer 1

I was getting the same error. I added the views.py in the trydjango folder instead of pages folder and it worked.

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

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

Answer 2

Received the same error during this tutorial. The issue was that I was using the "views.py" file from the "products" folder from earlier in the tutorial. You must make the HttpResponse code edits inside the "views.py" file located in the new "pages" folder.

Answer 3

Try changing your urlpatterns as follows:

path('', home_view, name='home'),
