find_one MongoDB Ruby Driver

Question

It looks like the current Ruby Mongo Driver 2.0.4 no longer has the find_one method. I can only find it in reference to GridFS.

How can I retrieve a single document from Mongo using the official ruby driver? The find method returns a collection not a single object.

Answer 1

find() returns a CollectionView which is a not-yet-executed query which behaves like an enumerable. To find just the first record:

find.limit(1).first

(Yes, it is annoying)
