To use ActiveRecord completely without rails, see HowToUseActiveRecordOutsideRails.
As with everything else in Ruby and Rails, it is pretty easy to use ActiveRecord outside of a web server.
By using the environment file, your script will use whatever database and whatever environment you’ve configured your system for.
Make a new file in the existing /script/ directory or in your own /shellscripts/ directory.
#!/usr/bin/env ruby
RAILS_ENV = 'production'
- This does NOT work. I looked back 3 revisions and found the correct line
#require File.dirname(__FILE__) + ‘/../config/boot’
require File.dirname(__FILE__) + ‘/../config/environment’
- use your models as you would normally
items = Railsmodel.find(:all)
items.each do |item|
begin
item.do_stuff
rescue Exception
puts $!
end
end
When you’re done, just run:
ruby recordrunner.rb (or whatever your file name is)
