What little things do I need to do before deploying a rails application

Question

EDIT

What small things which are too easy to overlook do I need to do before deploying a rails application?

I have set up another question for any task that takes more than a minute or two, and so ought to be scheduled into a deployment process. In this question I'm mostly concerned with on-line config options and similar, that can be done, but are often left out in during the development cycle because they don't make any difference until deployment

Answer 1

• Freeze the gems you are using rake gems:unpack
• Change the secret in config/environment.rb
• Filter sensitive informtion like passwords: in app/controllers/application.rb filter_parameter_logging :password, :password_confirmation

Answer 2

• Ensure the DB is setup on your production server
• Set up capistrano to deploy your app properly
  • Run a capistrano dry-run
• Ensure Rails is packed into your vendor/rails folder
• Ensure all gems are frozen in your app or installed on your prod server
• Run your tests on the production machine

Answer 3

• Include google analytics snippet (or other analytics)

Answer 4

• Check the slow query log, and add any indexes to your models which are causing full-table traverses.
