Greeting I'm passing my app to a production environment. All run okey but when I try to create my start up migration this error appears:

rake aborted! uninitialized constant ActiveRecord

And nothing happends. Anyone knows how to solve it?

rake db:migrate RAILS_ENV=production ?? just guessing fast.

I advice you to install SVN and Capistrano, because Capistrano will be helpful and enjoyable to do migration in your production server. I never have problem in migration using capistrano. You do nothing, if you run migration in your production server for your /home/username/app/project_name.

Thank you, I will request capistrano to my hosting provider.

Adittional information about my migration

#File 001_start_up.rb class StartUp < ActiveRecord::Migration

end

Anyone knows whats going on?
