587d7fb7367417b2b2512c0a	Create Many Records with model.create()	301537	2	使用model.create（）创建许多记录

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。Model.create() 接受一组像 [{name:'John', ...}, {...}, ...] 的数组作为第一个参数，并将其保存到数据库。

Instructions

修改 createManyPeople 方法，使用 arrayOfPeople 作为 Model.create() 的参数来创建多个 people 实例。 注意：你可以使用在上一个挑战中创建的 model 来完成当前挑战。

Tests

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); })'
