I am a hobo newbie. I installed 1.3.0.pre24. I have tryed several things
that work OK. But I am trying:
http://cookbook.hobocentral.net/recipes/64-single-table-inheritance-with-children
and at the end, when it's time for migration I get this error. I assume
the problem is with agent.rb but I cheched carefully and cannot find the
mistake. Would someone explain what happens please?
$ hobo generate migration
