See existing indexes in MongoDB using mongoid

问题

I'd like to see the existing indexes used by MongoDB. Can I do the equivalent of

$ mongod
> use my_db
> db.system.indexes.find()

using Mongoid?

$ rails console
> ?

Would be convenient from my heroku apps using MongoHQ. Thanks!

You can get at the underlying indexes for a Mongoid model through its collection.

> YourModel.collection.indexes

This reaches down into the moped driver (in Mongoid 3). See http://mongoid.org/en/moped/docs/driver.html
