--- id: 587d7fb8367417b2b2512c11 title: Delete Many Documents with model.remove() challengeType: 2 forumTopicId: 301538 dashedName: delete-many-documents-with-model-remove --- # --description-- `Model.remove()` is useful to delete all the documents matching given criteria. # --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. # --hints-- Deleting many items at once should succeed ```js (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); } ); ``` # --solutions-- ```js /** Backend challenges don't need solutions, because they would need to be tested against a full working project.
