Rails - Jul 2006 - ActiveRecords::Calculations

I have my Model<ActiveRecord::Base  ,

  but whenever I try something like

  Model.calculate() or Model.maximum ...

I get NoMethodErrors.

Why can I use any of the other ActiveRecord methods, but none from 
Calculations
and what do I do to remedy this?


thanks

Hai harl

  I think  the method name is matched with the field name of ur database 
table
check it.
