How to generate and set username in Laravel eloquent?

I have some fields in user table:

id  firstName  lastName userName

Here I need to generate and save an userName automatically where the user will provide only firstname & lastName. I have tried something like this but not sure about the piece of code.

User.php

class User extends Authenticatable{
...

protected $appends = ['firstName', 'lastName', 'userName'];

protected $attributes = ['userName' => 'default'];

 public static function boot()
    {
        parent::boot(); // TODO: Change the autogenerated stub

        self::creating(function ($model) {
            $randNum = rand(10, 99);
            $userName = $model['firstName'] . $model['lastName'] . $randNum;
            $model->userName = $userName;
        });
    }

}

So whenever I'm trying to migrate & seed it's showing

Field 'userName' doesn't have a default value

The seeder is

 public function run()
 {
        DB::table('users')->insert([
            'firstName' => 'Osman',
            'sureName' => 'Rafi',
            'email' => '[email protected]',
            'password' => Hash::make('password'),
           
        ]);
 }

What you're looking for is Model events.

First define a static boot method on your model. In there you can then run your username generation code.

class User extends Model 
{
    public static function boot()
    {
        parent::boot();

        self::creating(function($model){
            $randNum = rand(10, 99);
            $userName = $model['firstName'] . $model['lastName'] . $randNum;
            $model['userName'] = $userName;
        });
    }
}

This will intercept the creation of your model, and generate the username.

setUserNameAttributes function only works when you set username to model, not works automatically

you need to define setFirstNameAttribute function and inside it generate your username

Note: last word in function name is Attribute not Attributes*
