title: Create Many Records with model.create()
forumTopicId: 301537
challengeType: 2
localeTitle: 使用model.create（）创建许多记录
---

## Description
<section id='description'>
在一些情况下，比如进行数据库初始化，你会需要创建很多 model 实例来用作初始数据。<code>Model.create()</code> 接受一组像 <code>[{name:'John', ...}, {...}, ...]</code> 的数组作为第一个参数，并将其保存到数据库。
</section>

## Instructions
<section id='instructions'>
修改 <code>createManyPeople</code> 方法，使用 <code>arrayOfPeople</code> 作为 <code>Model.create()</code> 的参数来创建多个 people 实例。
<strong>注意：</strong>你可以使用在上一个挑战中创建的 model 来完成当前挑战。
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: 应当成功地一次性创建多个数据
    testString: 'getUserInput => $.ajax({url: getUserInput(''url'') + ''/_api/create-many-people'', type: ''POST'', contentType:''application/json'', data: JSON.stringify([{name: ''John'', age: 24, favoriteFoods: [''pizza'', ''salad'']}, {name: ''Mary'', age: 21, favoriteFoods: [''onions'', ''chicken'']}])}).then(data => { assert.isArray(data, ''the response should be an array''); assert.equal(data.length, 2, ''the response does not contain the expected number of items''); assert.equal(data[0].name, ''John'', ''The first item is not correct''); assert.equal(data[0].__v, 0, ''The first item should be not previously edited''); assert.equal(data[1].name, ''Mary'', ''The second item is not correct''); assert.equal(data[1].__v, 0, ''The second item should be not previously edited''); }, xhr => { throw new Error(xhr.responseText); })'
