Weekend update

This weekend I made several updates to the system.

• created scaffold and api for vocabulary review game

• created a view to export content data (questions and categorization data) data as a CSV file

This took me a while because I could not get the CSV file to be parsed correctly. Question text contained commas so I could not use that as the delimiter. Instead I used tabs. The other problem I had was that there existed \n and \r characters in the question text. To fix this I found some code that effectively cleansed the string. This was the final version:

<%= v.to_s.squeeze(' ').strip.chomp.gsub("\r","").gsub("\n", "")  + "\t" %>



• added a parent method to the stat model which returns the parent of the associated 

• created a way to collect and pull aggregated data from individual users

This week I will be working on the tutor interface.
