How do I modify rails associations from the command line?

Question

I added a relationship a little while ago to users (user has many cars). But my boss has told me I need to make a new model for companies which the cars will belong to the company and the leases will reside with the company so company leases to many uses. I can't find the specific migration that added the user_id to cars, so is there a way to say modify?

rails g migration user_id_to_company_id_on_cars

Sorry, the question is hard to understand. Why should you modify rails association from command line, I think it is just belongs_to or has_many in the model?

If you want to do a migration on a model, you can do for example:

rails g migration add_user_id_to_cars user_id:integer

I already have cars to users with a foreign key. What I need to do is change the foreign key to company_id. – user2327241 Apr 28 '13 at 06:01
