Instance Method Details

#state_fu_machine(*args, &block) ⇒ Object Also known as: machine

Given no arguments, return the default machine (:state_fu) for the class, creating it if it did not exist.

Given a symbol, return the machine by that name, creating it if it didn't exist, and definining it if a block is passed.

Given a block, apply it to a StateFu::Lathe to define a machine, and return it.

This can be done multiple times; changes are cumulative.

You can have as many machines as you like per class.

Klass.machine # the default machine named :om # equivalent to Klass.machine(:om) Klass.machine(:workflow) # another totally separate machine

recognised options are: :field_name - specify the field to use for persistence. defaults to machine_name_field.
