I have 2 jobs I would like to run and they are dependant on Models in my rails application. I added the ruby files in a separate folder called Jobs, that I have appended to the rail project.
Whenever I try to run them via ruby command I get the following error:
uninitialized constant Feedback (NameError).
Feedback here is a model I'm using in my rails app.
My questions: because the jobs I'm using are actually compatible with the script/runner command of rails 2, is there an alternative with Rails 3? If not how can I write ruby programs that depend on models I have in a rails app without getting the error I mentioned above.

The simplest way is with rails runner because you don't need to modify your script. runner runs Ruby code in the context of Rails non-interactively. If you make the script executable by running chmod +x script. rb , you can add #!/usr/bin/env rails runner to the top of the script, and then simply run it with ./script.
Run source code from the editor in a console To do this, perform the following steps: Open the required Ruby file in the editor (if necessary, select a fragment of code to be executed). From the main menu, choose Tools | Load file/selection into IRB/Rails console.
The Rails runner allows you to run Ruby code in the Rails context non-interactively. In RubyMine, you can run and debug project or scratch Ruby scripts in the Rails context.
Use rails runner
$ rails -h
Usage: rails COMMAND [ARGS]
...
runner Run a piece of code in the application environment
All commands can be run with -h for more information.
The "Rails 3 way" to do this is with Rake using the :environment prerequisite, which loads the Rails environment. Like so:
task :name => :environment do |t|
# actions
end
In the block you can load and execute your jobs.
If you haven't written Rake scripts before, here's a good tutorial. It's quite easy.
