I am new to Ruby on Rails and love what I see. I am also new to MySQL.
I am using a generic table with the ajax_scaffold. The table and
application are working great. However, I want to populate one column
for a new row based on the sum of other columns inputed by the user
when a new row is created.
The row represents a new user. Some of the columns for the user
represent test scores. One column is for a total score. How do I add
up the columns with scores and populate the total score column
