Method: Workflow::ClassMethods#workflow_column

Defined in:
lib/workflow.rb

#workflow_column(column_name = nil) ⇒ Object

Workflow does not provide any state persistence - it is the job of particular persistence libraries for workflow and activerecord or remodel. But it still makes sense to provide a default name and override feature.
