Generate a RubiGen::Base based application generator:

newgem foobar
script/generate application_generator foobar

add this to the manifest method on foobar_generator.rb to test the migration generation process:

m.migration_template 'test.rb', 'db/migrate',:migration_file_name => 'test'

and add a simple migration template:

class Test < ActiveRecord::Migration
  def self.up
  end

  def self.down
  end
end

Then try to use this generator:

chmod +x bin/foobar
bin/foobar test_app

This throws an "uninitialized constant":

uninitialized constant RubiGen::Commands::Base::ActiveRecord

I think this error is related to Rails dependencies no satisfied in [RUBIGEN_PATH]/lib/rubigen/commands.rb line 65:

Dir.glob("#{RAILS_ROOT}/#{@migration_directory}/[0-9]*_*.rb").inject(0) do |max, file_path|

and line 88:

if ActiveRecord::Base.timestamped_migrations

As workaround a simple require 'active_record' would fix it. Obviously this Rails dependencies could be not desired and a few changes in the rubigen gem will remove this dependency.

Let me know if a you a few test to clarify this issue.
