Description

有时你需要创建很多的 model 实例。例如：在使用初始数据为数据库初始化时，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

使用arrayOfPeople作为Model.create()的参数创建很多个 people 实例。

Tests

tests:
  - text: 应当可以一次性创建多个 item（项目）。
    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); })'
