# --description--
|

|
In this challenge you will have to create and save a record of a model.
|
||
|
|
|
||
|
|
# --instructions--
|
||
|
|
|
||
|
|
Within the `createAndSavePerson` function, create a document instance using the `Person` model constructor you built before. Pass to the constructor an object having the fields `name`, `age`, and `favoriteFoods`. Their types must conform to the ones in the `personSchema`. Then, call the method `document.save()` on the returned document instance. Pass to it a callback using the Node convention. This is a common pattern; all the following CRUD methods take a callback function like this as the last argument.
|
||
|
|
|
||
|
|
```js
|
||
|
|
/* Example */
|
||
|
|
|
||
|
|
// ...
|
||
|
|
person.save(function(err, data) {
|
||
|
|
// ...do your stuff here...
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|

Creating and saving a db item should succeed
|
||
|
|
|
||
|
|
```js
|
||
|
|
(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);
|
||
|
|
}
|
||
|
|
);
|
||
|
|
```
