Nova Json Wrapper

This field allows you to group Nova fields and merge their output into a single JSON column.

Installation

You can install the package via composer:

composer require digital-creative/nova-json-wrapper

Usage

Firstly you will need to update your model to cast the value of your attribute to an array:

class User extends Model
{
    protected $casts = [
        'options' => 'array'
    ];
}

Then create a JsonWrapper field within your nova resource and use the HasJsonWrapper trait.

use DigitalCreative\JsonWrapper\JsonWrapper;
use DigitalCreative\JsonWrapper\HasJsonWrapper;

class User extends Resource
{
    use HasJsonWrapper; // Important!

    public function fields(Request $request)
    {
        //...
        JsonWrapper::make('options', [

            Text::make('First Name')->rules('required'),
            Text::make('Last Name')->rules('required'),

            JsonWrapper::make('body_mass', [

                Text::make('Weight')->rules('required'),
                Text::make('Height')->rules('required'),

            ])

        ])
    }

}

This converts to

{ "first_name": "John", "last_name": "Doe", "body_mass": { "weight": 70, "height": 180 } }

and saves to the options column on the database.

Notes

There are no visual indications that the field is wrapped within a json, this is intentional. It was designed to work in condition with Conditional Container allowing to seamlessly create complex data structure and having it all saved in a single json column into your database, here is an full example:

public function fields(Request $request)
{
    Select::make('Type')
          ->options([
              1, 2, 3, 4, 5
          ])
          ->rules('required'),

    ConditionalContainer::make([

        JsonWrapper::make('data', [

            Text::make('First Name')->rules('required'),
            Text::make('Last Name')->rules('required'),

            Select::make('Gender')
                  ->options([
                      'male' => 'Male',
                      'female' => 'Female'
                  ])
                  ->rules('required'),

            ConditionalContainer::make([ JsonWrapper::make('extra', [ ... ]) ])->if('gender === male'),
            ConditionalContainer::make([ JsonWrapper::make('extra', [ ... ]) ])->if('gender === female'),

        ])

    ])->if('type >= 2'),
}
