Add schema validation before saving.

[florianJacques]

I suggest introducing an automatic schema validation mechanism before saving data to the database, inspired by the schema validation system in Mongoose (Node.js).
This validation would be handled at the model or persistence layer using Laravel’s native validation system (Illuminate\Validation\Validator).

Goals
• Prevent invalid or incomplete data from being saved.
• Centralize validation rules close to the model or schema definition.
• Improve maintainability and ensure data integrity.

Example Implementation

<?php

namespace App\Models;

use MongoDB\Laravel\Eloquent\Model;
use MongoDB\Laravel\Eloquent\SchemaValidation;

class Planet extends Model
{
    use SchemaValidation;

    public function schemaRules(): array
    {
        return [
            'name' => 'required|string',
            'distance' => 'integer|between:10,65535',
        ];
    }
}

<?php

$planet = \App\Models\Planet::query()->first();
$planet->name = 'Earth';
$planet->withValidation()->save();

Checklist

• Add tests and ensure they pass

Hello @florianJacques, thanks for bringing this idea.

Does this feature require to be part of the laravel-mongodb package, or is it something that could be provided by a third party package? On a quick search, I found watson/validating that is quite popular and seems to be very similar to what you describe.

Indeed, I didn't know this package. Thank you for taking the time to look at my proposal.

Let me know if you have any compatibility issue with MongoDB.
