--- id: 587d7fb7367417b2b2512c0a title: 使用 model.create() 创建多条记录 challengeType: 2 forumTopicId: 301537 dashedName: create-many-records-with-model-create --- # --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。 # --hints-- 应当成功地一次性创建多条数据 ```js (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); } ); ``` # --solutions-- ```js /** Backend challenges don't need solutions, because they would need to be tested against a full working project.
