Blogzz is a project mainly written in PYTHON and JAVASCRIPT, it's free.
Buzz blog integration using the tornado web framework
This example is designed to run in Google AppEngine, so there are a couple of steps to get it running. You can download the Google AppEngine Python development environment at http://code.google.com/appengine/downloads.html.
Link or copy the tornado code directory into this directory:
ln -s ../../tornado tornado
AppEngine doesn't use the Python modules installed on this machine. You need to have the 'tornado' module copied or linked for AppEngine to find it.
Install and run dev_appserver
If you don't already have the App Engine SDK, download it from http://code.google.com/appengine/downloads.html
To start the tornado demo, run the dev server on this directory:
dev_appserver.py .
Visit http://localhost:8080/ in your browser
If you sign in as an administrator, you will be able to create and edit blog posts. If you sign in as anybody else, you will only see the existing blog posts.
If you want to deploy the blog in production:
Register a new appengine application and put its id in app.yaml
First register a new application at http://appengine.google.com/. Then edit app.yaml in this directory and change the "application" setting from "tornado-appenginge" to your new application id.
Deploy to App Engine
If you registered an application id, you can now upload your new Tornado blog by running this command:
appcfg update .
After that, visit application_id.appspot.com, where application_id is the application you registered.
