README

Mutable JSON column casting for Laravel Eloquent. Supports JSON Schema validation via opis/json-schema.

Installation

You can install the package via composer:

composer require amol/laravel-jsonsafe

Usage

Basic casting

Cast a JSON column to JsonSafe in your model:

use Amol\LaravelJsonSafe\JsonSafe;

class User extends Model
{
    protected $casts = [
        'extras' => JsonSafe::class,
    ];
}

Read and write nested keys directly — changes persist on save():

$user->extras['theme'] = 'dark';
$user->save();

$user->extras['theme']; // 'dark'

JSON Schema validation

Define a public schemaOf{Key}() method on your model to enable validation. The column key is converted to StudlyCase and prefixed with schemaOf (e.g., preferences → schemaOfPreferences()).

use Amol\LaravelJsonSafe\JsonSafe;

class User extends Model
{
    protected $casts = [
        'preferences' => JsonSafe::class,
    ];

    public function schemaOfPreferences(): array
    {
        return [
            'type' => 'object',
            'properties' => [
                'appearance' => [
                    'type' => 'object',
                    'properties' => [
                        'theme' => [
                            'type' => 'string',
                            'enum' => ['light', 'dark', 'system'],
                        ],
                        'fontSize' => [
                            'type' => 'integer',
                            'minimum' => 10,
                            'maximum' => 24,
                        ],
                    ],
                ],
            ],
        ];
    }
}

If the data violates the schema, an Exception is thrown before the database write:

$user->preferences['appearance']['theme'] = 'invalid';
$user->save(); // throws Exception

Key mapping rules:

• preferences → schemaOfPreferences()
• my_column → schemaOfMyColumn()
• UPPERCASE → schemaOfUppercase()

Columns without a schema method are not validated.

Schemas follow the JSON Schema standard via opis/json-schema. You can use any supported keywords (type, properties, enum, required, minimum, maximum, pattern, etc.).

Serialization

toArray() and toJson() return the underlying plain array:

$user->extras->toArray(); // ['theme' => 'dark']

Testing

composer test
