Validation for Eloquent Models

Installation

composer require anourvalar/eloquent-validation

Usage

Creating with validation

\App\UserPhone
    ::fields('user_id', 'phone_number') // fillable columns (mass assignment)
    ->fill(\Request::input())
    ->validate() // will throw exception if it fails
    ->save();
}

Updating with validation

\App\UserPhone
    ::findOrFail(\Request::input('id'))
    ->fields(['user_id', 'phone_number']) // also might be an array
    ->fill(\Request::input())
    ->validate()
    ->save();
}

Generate model

php artisan make:model-validation UserPhone
