Migration from ActiveRecord to DataMapper. Who tried it?

Hey there,

the Datamapper ORM had my attention lately and the syntax and methods
seem quite similar to activerecord. Even validations could be converted
without much hassle.

The migration-free model changes sound like a dream.

Has anyone tried it and succeeded? Or are there other experiences with
DataMapper in Rails?

Just courious...


There’s a post about it, but I haven’t tried it myself: http://bustoutsolutions.com/blog/2007/09/17/getting-started-with-datamapper-and-rails/

It would indeed be nice if you could just distribute a rails app that could be just uploaded to a server (running mod_rails) and on first connect would ask for a database name and then automigrate.

Best regards
