Undefined method 'aasm_column' in seeds.rb

[onknows]

If AASM model files are used in seeds.rb it doesn't work. it shows the message "undefined method aasm_column' for -- aasm_column(:state) rake aborted! undefined methodaasm_column' for #ActiveRecord::ConnectionAdapters::MysqlAdapter:0xb6ed0268

I'm using aasm (2.1.5) with Rails 2.3.5

Abandoning idea to use AASM. Just too unclear on what to use, install, and from where. How to include this in my Rails app. Just not documented here. This way using AASM just involves a lot of guessing, assumptions.
