# --description--
|
||
|
|
|
||
|
|
在一些情況下，比如進行數據庫初始化，你會需要創建很多 model 實例來用作初始數據。 `Model.create()` 接受一組像 `[{name: 'John', ...}, {...}, ...]` 的數組作爲第一個參數，並將其保存到數據庫。
|
||
|
|
|
||
|
|
# --instructions--
|
||
|
|
|
||
|
|
修改 `createManyPeople` 方法，使用 `arrayOfPeople` 作爲 `Model.create()` 的參數來創建多個 people 實例。
|
||
|
|
|
||
|
|
**注意：** 你可以使用在上一個挑戰中創建的 model 來完成當前挑戰。
|
||

# --hints--
|
||
|
|
|
||
|
|
應當成功地一次性創建多條數據
|
||
|
|
|
||
|
|
```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);
|
||
|
|
}
|
||
|
|
);
|
