GradeSheet has been designed to give teachers all the tools they need to record student grades. It is web based to make it easily accessible to everyone. Students and parents can log into the system to check on their grades and even communicate with their teacher(s).

This is a typical Ruby on Rails project and it is installed just like any other RoR project. Since most of the development/testing is done on Debian & Ubuntu, it will be simpler to get up and running if you are using one of those OSs. However, it should run on any system that runs Rails.

  1. Get the source code (

  2. Add the dependencies noted in the Requirements section

  3. Modify database.yml to point to your database

  4. Run rake db:migrate to create the database schema

  5. Run rake fixtures:load to load the test data

  6. Run rake db:seed to load a bootstrap admin user

  7. Run ./script/server to start the development web server

  8. Fire up your web browser and point it to localhost:3000

  9. Log in as admin with a password of password and enjoy!

Building Documentation

Gradesheet is documented using the standard, built-in RDoc system. To build the documentation with the just run the command:

rake doc:app

However, to build better looking documentation you might want to use this command:

rake doc:app_horo

which uses the Horo template and results in documentation that is much easier on the eyes.


Currently, Gradesheet tests are written using the standard, built-in test framework. However, RSpec looks very attractive and when I get a bit more time I might move them over to that. In the meantime, just use the standard Rails testing commands to run the test (rails test:units, etc.)

I've just been turned on to Webrat and am very impressed with it and all of the integration tests (or the majority of them) will be soon converted to it. So, if you want to run the full test suite, you'll have to install the Webrat gem.

Performance testing is being implemented with the excellent JMeter package. This project uses Authlogic for user authentication and I have had no end of trouble trying to get some performance numbers out of the system. However, a little time spent with JMeter has gotten me a least a little way toward being able to measure the speed of the system. This is becoming ever more important as the design solidifies and the optimization begins.

Professional Support & Maintenance

If your interested in using Gradesheet in your school but don't want to install and maintain it yourself, consider using a KangarooBox server appliance running Kookaburra (the commercial version of Gradesheet).
