AttributeError: module 'posts.views' has no attribute 'home'

Question

Learning from a Udemy course I am taking by Nick Walter on Django, I am writing my own “Credit Card Redaction” app. The basic functionality is in place. But now I am trying to add a blog post app to go with it. I successfully initiated the app using $ python3 manage.py startapp posts. But as soon as I started filling in the urls.py, template and sub-views, my server has stopped running. I get:

File "/home//dev/projects/python/2018-and-2019/CC_Redact/CC_Redact/urls.py", line 10, in

url(r'^$', views.home, name='home'),

AttributeError: module 'posts.views' has no attribute 'home'

This is Django 2.0 with Python 3.6 using the built in test server (no where near production environment yet). I’m running my code inside an activated virtual environment. These are the contents of my requirements.txt:

Django==2.0.13

Pillow==5.4.1

psycopg2==2.7.7

psycopg2-binary==2.7.7

pytz==2018.9

Pretty basic, right?

urls.py in my primary project folder:

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


urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$', views.home, name='home'),
    url(r'^result/', views.result, name='result'),
    url(r'^james/', views.posts, name='james'), 

views.py (in app folder):

from django.shortcuts import render

# Create your views here.

def james(request):
    return render(request, 'posts/james.html')

As you can see, I've named my function "james", as well as my template.

Here is posts/templates/posts/james.html:

from django.shortcuts import render

# Create your views here.

def james(request):
    return render(request, 'posts/james.html')

Finally, here is my file tree and directory structure: .

When running the sever, I am expecting to see "You are in James' posts!" in bold text when navigating to localhost:8000/posts. Instead I am receiving:

python manage.py runserver

edit: btw: Here is my project on GitHub. I am accepting pull requests.

Answer 1

You really need to focus more on the course. view.posts refers there is a def with name posts call that def. In short view.posts calls posts def in view.

Change

def James(request):

To

def posts(request):

In view.py U also need to have a def with name "home"
