Converting referenced documents into embedded

So I'm using mongoid in my rails app and have been referencing all of my class relations by default.开发者_运维知识库 I've realized some of these would be better off being embedded and was just wondering if there are any extra steps to take besides just changing has_many to embeds_many, etc.

You'll need to create new embedded docs for each doc that exists in another collection.

For example, say you have Post and Comment, and Comment belongs to Post. Right now, your comments are in a collection called "comments". You're going to need to iterate through each of your posts or comments, and create an embedded comment in the correct post.
