title: Delete Many Documents with model.remove()
challengeType: 2
forumTopicId: 301538

## Description

<section id='description'>

`Model.remove()` is useful to delete all the documents matching given criteria.

</section>

## Instructions

<section id='instructions'>

Modify the `removeManyPeople` function to delete all the people whose name is within the variable `nameToRemove`, using `Model.remove()`. Pass it to a query document with the `name` field set, and a callback.

**Note:** The `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.

## Tests

<section id='tests'>

```yml
tests:
  - text: Deleting many items at once should succeed
    testString: |
      getUserInput => $.ajax({url: getUserInput('url') + '/_api/remove-many-people', type: 'POST', contentType:'application/json', data: JSON.stringify([{name: 'Mary', age: 16, favoriteFoods: ['lollipop']}, {name: 'Mary', age: 21, favoriteFoods: ['steak']}])}).then(data => {
        assert.isTrue(!!data.ok, 'The mongo stats are not what expected');
        assert.equal(data.n, 2, 'The number of items affected is not what expected');
        assert.equal(data.count, 0, 'the db items count is not what expected');
        }, xhr => { throw new Error(xhr.responseText); })
```
