Ruby / Rails - Reverse Migration - DDL to Ruby Code

Question

Any tools in Ruby or Rails that would allow me to extract from database all the table schema and generate Ruby equivalent "DLL" statements?

Something that would allow me to port schema from say Microsoft SQL Server to Postgres, or MySQL to Sqlite.

Answer 1

In Rails/ActiveRecord, you can use rake db:schema:dump to generate db/schema.rb, and rake db:schema:load to load it into a database.
