I want to make groups of active records by there attributes or there method dynamically for reporting purpose. How can I do that.

Suppose I have Sample ActiveRecord and it has 5 attributes say atr1,atr2,atr3,atr4,atr5and some methods say m1,m2,m3which return different values depending on logic. Now I want to do double grouping of Samplesany attribute or method. i-e Sudo-Code

   first groupby atr1 then groupby atr2
   first groupby atr4 then groupby m1

these attributes can be dynamic. I'll appreciate a method which will return hash of groups with keys as given attributes/methods value and values as groups founded.

Can somebody help me here please.
