ActiveRecords::Calculations

Rails
1

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.
