Advanced Challenge Search with Ruby & Redis



For our new CloudSpokes (on Rails!) site, we’d like to rebuild the Challenge search page using Redis. Our last Redis challenge got us hooked on the technology as we love the simplicity, speed and raw power.

We think an advanced challenge search page could leverage some of the inherit power of Redis.  The service will support the caller passing a parameter to determine the format of the results as a JSON object or an RSS formatted XML payload.

It’s easy to get started with Redis. It is already baked into Cloud Foundry and there is a Heroku add-on. It couldn’t be much simpler to get started. No integration with our API is required for this challenge; you can use the sample JSON data in the Assets section.

See the Additional Info section for links to more info.


Populate Redis with the sample challenge data from the Assets section. Feel free to add more data if needed. Provide an easy way to reload this data so that when more challenges are created, they can be added to Redis easily. A rails app is preferred by not required.

We are trying to replace our challenges page so write a search interface that searches the Redis data store by keyword and returns matching challenges based upon the following  combinations. For instance, I may want to search for all closed challenges with the keyword “Chatter” and in the “Heroku” category.

- Open / Closed challenge
- Keyword search against the challenge name
- Keyword search against the challenge categories (AWS, Google, Twilio, etc.)

Users should be able to sort ascending and descending by challenge name, start date, end date and challenge category.

Users can click on the returned records to view the challenge on CloudSpokes. See Create Tags for an Object and Search for Tags for an example.

Host your application on any PaaS platform that you like and provide the URL. Heroku offers a free Redis add-on while Redis is baked into Cloud Foundry. The Heroku for Java Workbook has a complete tutorial using Redis while there are plenty of Ruby examples available on the web. See the Additional Info section for some links.


Upload all your source code as a zip and provide any documentation and/or instructions that are needed to run the app. Please be clear and concise with any setup instructions.

An SWF video of your application using Jing would also be helpful but not required.

Your submission will be judged by a panel of peers based upon this criteria. If you would like to request an extension, please read Can challenge deadlines be extended for more time? on our FAQ. We do not want to grant extensions unless there is a valid reason.
