ruby - How to access environment in datamapper migration -


i have padrino server application datamapper orm layer. have database migration, say:

migrate 1, :test       execute 'some query'   end end

this migration run using command:

padrino rake dm:migrate -e <env>

now problem need access env in query (not choose schema or datamapper automatically, specific functionality). tried debugging migration see if there variable stores value, no luck. there way?

as turns out, since using padrino, can directly use padrino.env inside up do..end or down do..end blocks:

migrate 1, :test       env = padrino.env     execute "some query #{env}"   end end

although padrino specific, concept of environment. sure work other frameworks rails well.
