Django ImportError: No module named 'app' - python-3.4

Question

I have been using django 1.3 by now. But wanted to start with latest version 1.8.1 with python3.4I have started with the project.
Here is my directory structure:
├── myapp
│   ├── common
│   │   ├── admin.py
│   │   ├── __init__.py
│   │   ├── migrations
│   │   │   └── __init__.py
│   │   ├── models.py
│   │   ├── tests.py
│   │   └── views.py
│   ├── __init__.py
│   ├── __pycache__
│   ├── settings.py
│   ├── templates
│   │   └── home.html
│   ├── urls.py
│   └── wsgi.py
└── manage.py
*urls.py
from django.conf.urls import include, url
from django.contrib import admin
from . import views
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^$', "home", name='homepage'),
]
views.py
from django.shortcuts import render
def home(request):
render(request, "home.html", {"text":"Hello World!!!"})
settings
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'common',
)

ImportError: No module named 'common'

Answer 1

The path of manage.py looks unusual to me. manage.py is usually at the top level project directory. The problem you encounter stems from the fact that django roots the search path (i.e. sys.path) at the path of the manage.py script.
In your case, common's relative module path is actually myapp.common.
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'myapp.common',
)
Of course myapp is then actually the project in django lingo.
