Problems with Virtualenv and Django 1.4 -- deployment on uwsgi.

[Maciej Szlosarczyk]

Since I've upgraded the version of Django and started a new project on
it, I cannot make it work properly with uwsgi.

The problem is that django doesn't import apps from project tree. My
settings.py looks like this:

INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
# Uncomment the next line to enable the admin:
'django.contrib.admin',
# Uncomment the next line to enable admin documentation:
# 'django.contrib.admindocs',
#Practical apps:
'engine.blog',
)

My config for uwsgi looks like this (parsed by yaml):

uwsgi:
uid: www-data
gid: www-data
socket: /tmp/wsgi_dev.sosek.net.sock
module: django.core.handlers.wsgi:WSGIHandler()
chdir: /home/sosek/nginx/dev.sosek.net/apps/engine
env: DJANGO_SETTINGS_MODULE=engine.settings
virtualenv: /home/sosek/.virtualenvs/dev.sosek.net
pythonpath: /home/sosek/nginx/dev.sosek.net/apps

When I use from inside of the virtualenv "python manage.py runserver"
i get something like:
Error: No module named blog

For UWSGI, most recent calls look like this:

you should update your module directive to

module: engine.wsgi

Check latest official Django docs on uWSGI
