Hey Guys, Again, I am just learning Rails, so I am asking advice here. I have a model called Company which has many Owners.

I created a model with some internal state derived from a combination of database and non-database data. Since I wanted to calculate these values once rather than every time they''re requested by the view, I calculated them in the initialize method and set some instance variables. However, I soon noticed that these values weren''t getting set when I retrieved data using the
