Question

I have to run this script: /scripts/saveData.rb

And in it, I need to use ActiveRecord of my Rails application.
I tried to invoke Class, but I get error "uninitialized constant (NameError)".

How can I get a reference to the Rails classes from my saveData.rb script?

Rails 3.1

UPDATED: how i can invoke a method of a Model? My model is: “Program” (also Active Record). I tried with “Program.method” but it doesnt works, why?

Answer 1

Which version of rails you are using?

You can run your code in Rails runner like this if you are using Rails 3:

http://guides.rubyonrails.org/command_line.html#rails-runner

$ rails runner script/saveData.rb

If you are using Rails 2, try this one:

$ script/runner script/saveData.rb
