How do I rename a mongo collection in Mongoid?

mongoid, mongoid3

Solution

From the Mongoid Docs:

class Band
  include Mongoid::Document
  store_in collection: "artists", database: "music", session: "secondary"
end

Use `store_in collection: "artist_lookups"` in your model. This will let you store your `Artist` model in the `artist_lookups` collection.

If you want to preserve the existing data in the `artists` collection, and rename it, I suggest shutting down your app temporarily, renaming the collection to `artist_lookups` on your MongoDB server, and then restarting the app.

Problem

I have a collection called artists, i'd like to rename it to artist_lookups. How do I do this?
