Hi All,
I'm trying to use DataMapper dm-is-versioned in a rails application.
Even when doing a simple test outside of rails I cannot get
the ::Versions table created. The error is always '<Model
Name>::Version must have a key to be valid. I pasted a simple test
below with a model and a ruby script to try to version the model. The
problem occurs when I try to auto_migrate!. I am using dm-core
(0.10.2) and dm-sis-versioned (0.10.2)
Any help will be appreciated.
thanks,
Leo
