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

I am talking to multiple databases using Mongoid.override_database("database_name") using Mongoid with rails. How do I find the current database programmatically?

Mongoid docs on sessions: http://mongoid.org/en/moped/docs/driver.html define methods to override database but do not define a way to get the current database in use.

Running Mongoid.default_session.options[:database] gives an error that default_session is invalid. It is now default_client. That works wonderfully.

Run it without the [:database] to get all the option and see the full configuration of your database.

Mongoid::Config.clients["default"]["database"] assumes you are NOT using the uri version of mongoid.yml. You will get nil in all cases. Use Mongoid::Config.clients["default"] to get the full configuration of the current database, or Mongoid::Config.clients["default"]['uri'] to give you just the full uri.

Pick the database name from the URI after the last port number/. There could be severalif using a sharded configuration

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.

If you want the overrided database you actually need to use

Mongoid::Threaded.database_override
