How to get last N documents with mongoid?

Question

I have found some information to accomplish this in mongoDB, but I need it with mongoid. So I can do something like:

User.last(7000).each do ....

I'm using:

• MongoDB shell version: 2.4.3

• Mongoid 2.6.0

Thanks!

Answer 1

Now I found a solution from mongoid origin:

User.all.desc('_id').limit(7000)

It sorts the users in descending order according to the id.
