Too few arguments to function Illuminate\Database\Eloquent\Model::setAttribute(), 1 passed - php

Question

i want to ask about error "Too few arguments to function Illuminate\Database\Eloquent\Model::setAttribute(), 1 passed "
i try to register users, i use php artisan make:auth to build my authentication. But, i add one field in users migration. and i try to use uuid. this is my code :
User Model
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use App\Traits\Uuids;
class User extends Authenticatable
{
use Notifiable;
use Uuids;
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $guarded = ['id'];
protected $table = 'users';
protected $fillable = [
'name', 'email', 'password','phone_number',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
}
Register Controller
<?php
namespace App\Http\Controllers\Auth;
use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Http\Request;
class RegisterController extends Controller
{

use RegistersUsers;
/**

*
* #var string

protected $redirectTo = '/home';
/**

public function __construct()
{
$this->middleware('guest');
}
/**
* Get a validator for an incoming registration request.
*
* #param array $data
* #return \Illuminate\Contracts\Validation\Validator

protected function validator(array $data)
{
return Validator::make($data, [
'name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'phone' => 'required|numeric|min:8',
'password' => 'required|string|min:6|confirmed',
'password_confirmation' => 'required|same:password',
]);
}
/**

* #param array $data
* #return \App\User
*/
protected function create(array $data)
{
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'phone_number' => $data['phone'],
'password' => Hash::make($data['password']),
]);
}
}
Users Migration
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUsersTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->uuid('id');
$table->string('name');
$table->string('email')->unique();
$table->string('password');
$table->integer('phone_number');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('users');
}
}
Uuids Trait
<?php
namespace App\Traits;
trait Uuids
{
/**
*
*/
protected static function boot()
{
parent::boot();
static::creating(function ($model) {
$model->{$model->uuid} =
str_replace('-', '', \Uuid::generate(4)->string);
});
}
}
Please give me advice. Thank You.

Answer 1

I can't find any reference about property or magic property you wrote as below (like a method getUuidAttribute for example)
$model->{$model->uuid} = str_replace('-', '', \Uuid::generate(4)->string);
So, I assume above code would compiled as
$model->{null} = str_replace('-', '', \Uuid::generate(4)->string);
I guess you're looking for $model->id which has the type of database column as a uuid. But, obviously, you can't have a dynamic database column name as it is wrong at all. Example of dynamic column if your snippet is working properly
$model->'6b324d55-433c-455a-88b6-feb2ee6c3709' = 'c3bec822-e5ee-4d91-b1a3-f5f552fd004a';
Something isn't right, right? It would be better if it look like this.
$model->id = 'c3bec822-e5ee-4d91-b1a3-f5f552fd004a';
And of course, make your latest snippet be something as follow
<?php
namespace App\Traits;
trait Uuids {
// to make model run this 'boot' method, append it with your trait name
protected static function bootUuids() { // <-- bootUuids
// parent::boot();
static::creating(function ($model) {
$model->id = str_replace('-', '', \Uuid::generate(4)->string);
});
}
}

Answer 2

Assuming your tables use UUID for primary key
$table->uuid('id')->primary();
Review your trait by setting the value directly to the id
<?php
namespace App\Traits;
use Illuminate\Support\Str;
trait UsesUuid
{
protected static function bootUsesUuid()
{
static::creating(function ($model) {
if (! **$model->id**) {
**$model->id** = (string) Str::uuid();
}
});
}
public function getIncrementing()
{
return false;
}
public function getKeyType()
{
return 'string';
}
}
Now use trait in your model
<?php
namespace App\Models;
use App\Traits\UsesUuid;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Group extends Model
{
use HasFactory;
**use UsesUuid;**
