title: Create and Save a Record of a Model
challengeType: 2

## Description

<section id='description'>

In this challenge you will have to create and save a record of a model.

</section>

## Instructions

<section id='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...
});
```

    testString: |
      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); })
