Nova Nested Form
================

[](#nova-nested-form)

This package allows you to include your nested relationships' forms into a parent form.

Installation
============

[](#installation)

```
composer require yassi/nova-nested-form
```

Contributions
=============

[](#contributions)

As I did not anticipate so many people would use that package (which is awesome) and simply do not have enough time to update/enhance this package more regularly on my own, I am looking for other contributors to help me with the maintenance and feature requests. Don't hesitate to contact me if you're interested!

Update to 3.0
=============

[](#update-to-30)

The **afterFill** and **beforeFill** methods are no longer available.

Attach a new relationship form to a resource
============================================

[](#attach-a-new-relationship-form-to-a-resource)

Simply add a NestedForm into your fields. The first parameter must be an existing NovaResource class and the second parameter (optional) must be an existing HasOneOrMany relationship in your model.

```
namespace App\Nova;

use Laravel\Nova\Fields\ID;
use Illuminate\Http\Request;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Fields\Gravatar;
use Laravel\Nova\Fields\Password;
// Add use statement here.
use Yassi\NestedForm\NestedForm;

class User extends Resource
{
    ...
    public function fields(Request $request)
    {
        return [
            ID::make()->sortable(),

            Gravatar::make(),

            Text::make('Name')
                ->sortable()
                ->rules('required', 'max:255'),

            Text::make('Email')
                ->sortable()
                ->rules('required', 'email', 'max:254')
                ->creationRules('unique:users,email')
                ->updateRules('unique:users,email,{{resourceId}}'),

            Password::make('Password')
                ->onlyOnForms()
                ->creationRules('required', 'string', 'min:6')
                ->updateRules('nullable', 'string', 'min:6'),

            // Add NestedForm here.
            NestedForm::make('Posts'),
        ];
    }
```

Choose when to display the form
===============================

[](#choose-when-to-display-the-form)

For instance, if the nested form should only be available if the value of the "has\_comments" attirbute is true, you can use:

```
class Post extends Resource
{
    ...
    public function fields(Request $request)
    {
        return [
            Boolean::make('Has Comments'),
            NestedForm::make('Comments')->displayIf(function ($nestedForm, $request) {
               return [
                    [ 'attribute' => 'has_comments', 'is' => true ]
               ];
        ];
    }
})
```

The **displayIf** method is excepted to return an array of array as you may want to add several conditions.

```
class Post extends Resource
{
    ...
    public function fields(Request $request)
    {
        return [
            Boolean::make('Has Comments'),
            Text::make('Title'),
            Text::make('Subtitle')->nullable(),
            Number::make('Number of comments allowed'),
            NestedForm::make('Comments')->displayIf(function ($nestedForm, $request) {
                return [
                    [ 'attribute' => 'has_comments', 'is' => true ],
                    [ 'attribute' => 'title', 'isNotNull' => true ],
                    [ 'attribute' => 'subtitle', 'isNull' => true ],
                    [ 'attribute' => 'title', 'includes' => 'My' ],
                    [ 'attribute' => 'number_of_comments_allowed', 'moreThanOrEqual' => 1 ],
                ];
            })
        ];
    }
}
```

The package will then add those conditions and dynamically update your form as you fill the fields. The available rules are:

- is
- isNot
- isNull
- isNotNull
- isMoreThan
- isMoreThanOrEqual
- isLessThan
- isLessThanOrEqual

Add a minimum or a maximum number of children
=============================================

[](#add-a-minimum-or-a-maximum-number-of-children)

For instance, if you want every user to have at least 3 posts and at most 5 posts, simply use:

```
NestedForm::make('Posts')->min(3)->max(5),
```

Please note that the package automatically detects whether the relationship excepts many children or a single child, and sets the maximum value accordingly.

When creating a new user, 3 blank posts will be displayed. If you reach the maximum number of posts, the "Add a new post" button will disappear.

Set the default open/collapse behavior
======================================

[](#set-the-default-opencollapse-behavior)

If you want the nested forms to be opened by default, simply use:

```
NestedForm::make('Posts')->open(true),
```

Modify the default heading
==========================

[](#modify-the-default-heading)

You can modify the default heading using the heading() method. You can use the helper method **wrapIndex()** to add the current child index to your header.

```
NestedForm::make('Posts')->heading(NestedForm::wrapIndex() . ' // Post'),
```

You can also add any attribute of the current child into your heading using the helper method **wrapAttribute()**.

```
NestedForm::make('Posts')->heading(NestedForm::wrapIndex() . ' // ' . NestedForm::wrapAttribute('title', 'My default title')),
```

Modify the index separator
==========================

[](#modify-the-index-separator)

You can modify the default index separator using the separator() method when you have nested forms (e.g. 1. Post, 1.1. Comment, 1.1.1. Like).

```
NestedForm::make('Posts')->separator('\'),

```
