Laravel model validation rules

This package is an alternative to the Laravel built-in validation rules exist and unique. This has the following advantages:

• It uses existing models instead of directly querying the database.
• The rule can be easily extended with the Eloquent builder.
• Softdeletes are working

Installation

You can install the package via composer with following command:

composer require korridor/laravel-model-validation-rules

Translation

If you want to customize the translations of the validation errors you can publish the translations of the package to the resources/lang/vendor/modelValidationRules folder.

php artisan vendor:publish --provider="Korridor\LaravelModelValidationRules\ModelValidationServiceProvider"

Rules

ExistEloquent

UniqueEloquent

        'title' => ['string'],
        'content' => ['string'],
        'comments.*.id' => [
            'nullable',
            new ExistEloquent(Comment::class, null, function (Builder $builder) use ($postId) {
