* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

587d7fb8367417b2b2512c0f 在 document 中执行新的更新方式——使用 model.findOneAndUpdate() 2 301542 perform-new-updates-on-a-document-using-model-findoneandupdate

--description--

最近发布的 mongoose 版本简化了 document 的更新方式, 但同时,一些高级功能(如 pre/post hook, 验证)的使用方式也变得和以前不同。因此,在很多情景下,上一个挑战中提到的老方法其实更常用。 新方法的加入,可以让我们使用 findByIdAndUpdate() 来进行基于 id 的搜索。

--instructions--

修改 findAndUpdate 函数,通过 Name 查询人,并将查到的人的年龄设为 20 岁, 将函数参数 personName 作为查询关键字。

提示: 你需要返回更新后的 document。 你可以把 findOneAndUpdate() 的第三个参数设置为 { new: true } 。 默认情况下,这个方法会返回修改前的数据。

--hints--

应成功地使用 findOneAndUpdate 更新数据

(getUserInput) =>
  $.post(getUserInput('url') + '/_api/find-one-update', {
    name: 'Dorian Gray',
    age: 35,
    favoriteFoods: ['unknown']
  }).then(
    (data) => {
      assert.equal(data.name, 'Dorian Gray', 'item.name is not what expected');
      assert.equal(data.age, 20, 'item.age is not what expected');
      assert.deepEqual(
        data.favoriteFoods,
        ['unknown'],
        'item.favoriteFoods is not what expected'
      );
      assert.equal(
        data.__v,
        0,
        'findOneAndUpdate does not increment version by design!'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
