Would you know what should I do to fix this ?

Made a few abstractions, additions, protections https://gist.github.com/jphenow/5694169

Extracting the tasks into a class for easier extension:

I added Rspec testing, improved Heroku toolbelt support, and post-deploy rake task running on my fork.

Great task! :)

A interesting thing happened the other day while I was using it to deploy code and run migrations.

Heroku Toolbelt detected that there is an update available and started updating itself in the middle of a running task. This resulted in maintenance mode being turned on, code being deployed and all other tasks cancelled because of the "update in progress" status. This left the environment down and its DB "unmigrated".

I recommend adding another task that is run first:

  task :update_toolbelt do
    puts 'Checking for Heroku Toolbelt updates ...'
    puts `heroku update`
    puts `heroku plugins:update`
  end

And you probably want to run it first when deploying to production. For example:

task :deploy_production => ['deploy:update_toolbelt', 'deploy:set_production_app', 'deploy:push', 'deploy:restart', 'deploy:tag']

namespace :deploy do
  ...
  task :production_migrations => [:update_toolbelt, :set_production_app, :push, :off, :migrate, :restart, :on, :tag]

Hope this helps!

EDIT: Added the plugin update check.
