uninitialized constant ClassName::Enum

Should mention I use padrino, but above error occurs when trying to upgrade using migrations. No problem using Enum in my models so I guess it is purely a migrations problem.

Yes it is listed in my Gemfile.lock file. It worked before I updated ruby/gem/padrino packages on my Ubuntu.

I fixed it temporarily by using DataMapper::Property::Enum instead of just Enum.

I'm having the same issue. Any updates?

Is dm-types listed somewhere in your Gemfile.lock? It's required to make the Enum type available when defining your models.
