Hot off the trac patches is my patch for ActiveRecord Calculations (heavily based on my plugin): http://dev.rubyonrails.org/ticket/3958. Not only does it replace the count method, but it adds methods for sum, maximum, minimum, and average. I think the coolest part, however, is using grouped queries against belongs_to assocations:
class Order < AR::Base belongs_to :person end orders = Order.calculate :sum, :quantity, :group => 'person_id' orders['5'] => 55 person = Person.find(5) orders = Order.sum :quantity, :group => :person orders[person] => 55 Scoped queries are possible too: person.orders.sum :quantity => 55 I'm mostly interested in these things: Is backwards compatibility maintained with #count? So far tests pass and it seems to work for me. Are my data type assumptions good? I'm always returning fixnums for COUNT and floats for AVG. Everything else depends on the column's data type. Is the documentation good? If you're still confused on some aspects, let me know so I can clarify a bit better.
