Usually what I do is get the migration done, get the models built, and then open up Console and enter some records that way. (I don't include validations in the models at this point but I do make the model associations). That way I can create users, their addresses, their tasks, etc... and know that I have data that will relate. Then I just use the below plugin to dump it out. not quite like what you're looking for but I hope it helps.
