Question

I’ve never had anything but success w/ Rails migrations, so this one is especially perplexing to me. I have a migration that I just wrote, it’s fairly simple, but when I try and run it (for the first time, or after rolling back and trying again), there is no output to the console for a few seconds, the job ends, and no change has occurred to my DB, other than checking rake db:migrate:status will show the migration has run (or, it thinks it has).

Migration code is here:

class AddNotesToCases < ActiveRecord::Migration
    def up
      add_column :cases, :notes, :text
    end

    def down
      remove_column :cases, :notes
    end
  end

db is PostGres, Rails is 3.0.9, rake is 0.9.2.2

EDIT **
per request, the results of a trace on the rake call are:

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
** Invoke db:schema:dump (first_time)
** Invoke environment 
** Execute db:schema:dump

FWIW, I also have tried rewriting the migration to use a String instead of Text datatype, and also have tried using the def change rather than up/down. No joy on any of them.

Gah, ok, after re-generating the file from scratch I realized when going from the change version to the up/down version, I’d typeoed the methods and forgot the ‘self’ on them. 😐

def self.up

worked where my code didn’t.
