Thanks, I followed your advice. And its almost fine. The original script operated with the models, putting it to a migration causes take the migration misses the model. Claims "uninitialized constant" for the model name. I tried to require the model directly. On the other hand I am not sure whether using models in migrations is intended.... currently it seems to be the most convenient way of changing the data.
