Pass ruby script file to rails console

Question

Is there a way to pass ruby file, foo.rb to rails console. Expected results would be after console starts rails environment to run file.

Or any other way which

Answer 1

Of these approaches mentioned earlier, none seemed clean and ideal like you would expect a standalone script to run (not get eval-ed or piped via < redirection), but finally this works perfect for me:

(for Rails 3)

Insert at the top of your script:

#!/usr/bin/env ruby

APP_PATH = File.expand_path(appdir = '/srv/staging/strat/fundmgr/config/application',  __FILE__)
require File.expand_path(appdir + '/../boot',  __FILE__)
require APP_PATH
# set Rails.env here if desired
Rails.application.require_environment!

# your code here...

Of course, set your own Rails app path in the APP_PATH line.

That way, I can avoid having to enter any interactive irb or rails c and can test my script.rb from the shell prompt, before eg. scheduling it in crontab.

It smoothly supports command-line parameters, too, and minimizes the levels of wrappers before getting to your code.
