I want to assign a progressive number to an attribute.
I think that I can do this in the model
class Model < ActiveRecord::Base
before_validation(:on => :create) do
attribute = Model.count + 1
But there is no method count for Model.
Is Model just an example, or did you use that as your model name?
There is definitely the count method on this page:
