--description--

在这个挑战中,你需要给之前创建的模型添加一条数据。

--instructions--

用我们在上一个挑战中写好的 Person 构造函数创建 document 实例:将包含 nameagefavoriteFoods 的对象传给构造函数。它们的数据类型必须符合我们在 Person 原型中定义的类型。然后在返回的 document 实例上调用方法 document.save()。同时,我们需要像之前提到过的那样,为它传一个回调函数。在 Mongoose 中,所有的 CRUD 方法接收的最后一个参数都是回调函数。

/* 示例 */

// ...
person.save(function(err, data) {
  //   ...do your stuff here...
});

--hints--

应成功地创建数据,并保存到数据库

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/create-and-save-person').then(
    (data) => {
      assert.isString(data.name, '"item.name" should be a String');
      assert.isNumber(data.age, '28', '"item.age" should be a Number');
      assert.isArray(
        data.favoriteFoods,
        '"item.favoriteFoods" should be an Array'
      );
      assert.equal(data.__v, 0, 'The db item should be not previously edited');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
