How to programmatically get the current database Mongoid is writing to?

If you want the overrided database you actually need to use

Mongoid::Threaded.database_override

The new way to get this is

Mongoid::Config.clients["default"]["database"]

You can also just have a look at

Mongoid::Config.clients

to see what else is available.

Got it!

Mongoid.default_session.options[:database]
