How to rename model

Question

I made a mistake early in development, and named one of my models with plural noun (Users instead of User). Is there an easy way to rename it and corresponding controller (similar to generating it with script/generate way)?

update: this script is not supported anymore

A script exists that will do the job for you:

nice! not something I'm likely to need often, but good to know it's out there. – stephenmurdoch Mar 18 '10 at 13:02
I'm bookmarking that one, because it's a PAIN to undo them. Most of the time I just git revert and regenerate. – wesgarrison Mar 20 '10 at 01:19

Is it possible to use it with rails 3? – mirelon Dec 17 '12 at 14:52

You'll have to change all the references to Users in all your application manually.

To change the name by itself, it's not very hard : rename the file and add the following migration :

class RenameUsers < ActiveRecord::Migration
    def self.up
        rename_table :users, :user
    end
    def self.down
        rename_table :user, :users
    end
end

Table name should be plural, thus "users" is fine. – kouak Mar 18 '10 at 11:22
Right ! But in his model, the table is probably not named users so he'll have to rename it – Damien MATHIEU Mar 18 '10 at 13:03

You need to rename your file, your test/spec file and all reference to this model.

You also need to make a migration to rename the table.
