How to Self Validate Eloquent Model Before Save in Laravel

There are several packages on the web to validate the model, but most of them are not working with newer Laravel versions. That’s why Minute of Laravel created a simple model class as a package for this purpose which is called Laravel Self Validating Model. This package contains an extended Eloquent Model class which self-validates against validation rules specified in the Model’s rules property when the Model is saved/updated.

It works with:

• Laravel 9
• Laravel 8
• Laravel 7
• Laravel 6

Installation

You can install this package via composer:

composer require minuteoflaravel/laravel-self-validating-model

How to use

Let’s say we have a Contact model which extends Illuminate\Database\Eloquent\Model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Contact extends Model
{
    use HasFactory;
}

Instead of extending Illuminate\Database\Eloquent\Model we should extend MinuteOfLaravel\Validation\SelfValidatingModel:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use MinuteOfLaravel\Validation\SelfValidatingModel as Model;

class Contact extends Model
{
    use HasFactory;
}

Then just add you validation rules to the $rules property:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use MinuteOfLaravel\Validation\SelfValidatingModel as Model;

class Contact extends Model
{
    use HasFactory;
    
    public $rules = [
        'first_name' => 'required',
        'last_name' => 'required',
        'email' => 'required|email:rfc,dns,spoof',
    ];
}

That’s it! The model will be validated on save/update.
