Welcome to Rietveld

This project shows how to create a somewhat substantial web application using Django on Google App Engine. It requires Django version 1.0.

In addition, I hope it will serve as a practical tool for the Python developer community, and hopefully for other open source communities. As I've learned over the last two years at Google, where I developed a similar tool named Mondrian, proper code review habits can really improve the quality of a code base, and good tools for code review will improve developers' life.

Some code in this project was derived from Mondrian, but this is not the full Mondrian tool.

Running

NEW YOU MUST INSTALL DJANGO 1.0 FIRST BEFORE RUNNING LOCALLY.

Download Django-1.0.2-final.tar.gz from www.djangoproject.com (or whatever the latest micro-version of 1.0 is) and follow the installation instructions. Typically:

tar xzf Django-1.0.2-final.tar.gz cd Django-1.0.2-final sudo python setup.py install

NOTE: On the Mac, if you are using the Google App Engine Launcher, the Python version it uses may differ from the default you have on the command line. To install Django into the correct Python version, you may have to do the following:

sudo /usr/bin/python setup.py install

To run the app locally (e.g. for testing), download the Google App Engine SDK from http://code.google.com/appengine/downloads.html. You can then run the server using

make serve

(assuming you're on Linux or Mac OS X).

The server is only accessible on http://localhost:8080. The server in the Google App Engine SDK is not designed for serving real traffic. The App Engine FAQ at http://code.google.com/appengine/kb/general.html says about this: "You can override this using the -a flag when running it, but doing so is not recommended because the SDK has not been hardened for security and may contain vulnerabilities."

To deploy your own instance of the app to Google App Engine:

1. Register your own application ID on the App Engine admin site.
2. Edit app.yaml to use this app ID instead of 'codereview'.

3. Upload using

   make update

*** Don't forget step 2! If you forget to change the application ID, you'll get a error message from "appcfg.py update" (called by "make update") complaining you don't have the right to administer this app.
