rake db:migrate not working?

Reported by mark | September 18th, 2010 @ 02:59 AM | in 1.1

I'm not sure whether it's my or dm-rails's issue but I couldn't get the raketask to work.

Source of the problem is that migration module is included into Object namespace in order to make shortcuts (like migrate {}) possible:

include DataMapper::MigrationRunner

The raketask, on other hand, uses full module path as in:

::DataMapper::MigrationRunner.migrate_up!

::DataMapper::MigrationRunner and ::Object have different instance variables so method

def migrations
  @migrations ||= []
end

will return different values for migrator raketask and for migrate ruby scripts in db/mgirate/*.

There are different ways to solve that, the most backward compatible is probably running migrate_up! directly from Object. On other hand, using the root-level namespace is a kind of mauvais ton.
