# --description--
|
|
|
|
`findByIdAndRemove` and `findOneAndRemove` are like the previous update methods. They pass the removed document to the db. As usual, use the function argument `personId` as the search key.
|
|
|
|
# --instructions--
|
|
|
|
Modify the `removeById` function to delete one person by the person's `_id`. You should use one of the methods `findByIdAndRemove()` or `findOneAndRemove()`.
|
|
|
|
# --hints--
|
|
|
|
Deleting an item should succeed
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.post(getUserInput('url') + '/_api/remove-one-person', {
|
|
name: 'Jason Bourne',
|
|
age: 36,
|
|
favoriteFoods: ['apples']
|
|
}).then(
|
|
(data) => {
|
|
assert.equal(data.name, 'Jason Bourne', 'item.name is not what expected');
|
|
assert.equal(data.age, 36, 'item.age is not what expected');
|
|
assert.deepEqual(
|
|
data.favoriteFoods,
|
|
['apples'],
|
|
'item.favoriteFoods is not what expected'
|
|
);
|
|
assert.equal(data.__v, 0);
|
|
assert.equal(data.count, 0, 'the db items count is not what expected');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
