RoR environment in Ruby standalone script

I want to run a standalone ruby script in which I need my RoR environment to be used. Specifically, I need my models extending ActionMailer and ActiveRecord. I also need to read the database configuration from my database.yml. How do I go about it?

From stackoverflow

• The easiest way is to change the shebang of your script from :

  #!/usr/bin/ruby
  

  to

  #!/path/to/your/rails/script/runner
  

  Et voilà, your script will be run with the full rails environment loaded. You can also run your script as ./my_script -e production to have it run with the production database.

• Check out this thread: http://stackoverflow.com/questions/293302/how-do-i-run-ruby-tasks-that-use-my-rails-models

  Essentially it boils down to:

  require "#{ENV['RAILS_ROOT']}/config/environment.rb"
  

  Have fun!

• I think the best way to do this is to make it a rake task.

     # lib/tasks/mystuff.rake
     desc 'do my stuff'
     task :my_stuff => [:environment] do
       # do my stuff
     end
  

  The [:environment] stanza loads the rails environment.
