Is there a method in Criteria that will print the actual MongoDB query that criteria is generating?
If you inspect Mongoid Criteria instance, you will see “selector” which maps (essentially) directly to the MongoDB selector. However Mongoid Criteria can be chained and are evaluated lazily, so the result of chaining and lazy evaluation is not available until you do an actual DB operation. So if you want to see the final result, you should look in the appropriate log. For a test, this is log/test.log, for “rails c” console, this is log/development.log — this is standard.
