Description

Model.remove() is useful to delete all the documents matching given criteria. Delete all the people whose name is “Mary”, using Model.remove(). Pass it to a query document with the “name” field set, and of course a callback. Note: Model.remove() doesn’t return the deleted document, but a JSON object containing the outcome of the operation, and the number of items affected. Don’t forget to pass it to the done() callback, since we use it in tests.

Instructions

Tests

tests:
  - text: Deleting many items at once should succeed
