Following on from @Bryan Larsen, if you're using an abstract Class to attach a series of models to a different database, and would like to migrate schemas on them, then you can do this:

class CreatePosts < ActiveRecord::Migration
    def connection
      Post.connection
    end
    def up
      ...
    end
end

with a model set up something like:

class Post < ReferenceData
end

and

class ReferenceData < ActiveRecord::Base
  self.abstract_class = true
  establish_connection "reference_data_#{Rails.env}"
end
