Simple mutator screwing with SQL Query? - Laravel - php

Question

I want to be able to set the user_id via the setUserIdAttribute mutator but it won't work. The code works fine when I comment out the mutator. Below is my code and the resulting QueryException error. Please help!
// EventController.php
public function store(Request $request)
{
Event::create([
'name'=>'myName',
'user_id'=>'1'
]);
return 'Success!';
}
// Event.php
class Event extends Model
{
protected $fillable = ['name', 'user_id'];
// It works as expected if I comment this out.
public function setUserIdAttribute($value)
{
// I know this code will run. If i do echo 'foo' it works.
return '1';
}
}
// The migration file
public function up()
{
Schema::create('events', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users');
$table->timestamps();
});
}
// The error I get
SQLSTATE[HY000]: General error: 1364 Field 'user_id' doesn't have a default value (SQL: insert into `events` (`name`, `updated_at`, `created_at`) values (myName, 2017-04-23 22:28:31, 2017-04-23 22:28:31))

Answer 1

I think $this->attributes['attribute_name'] is the correct way to mutate.
// Event.php
class Event extends Model
{
protected $fillable = ['name', 'user_id'];
// It works as expected if I comment this out.
public function setUserIdAttribute($value)
{
// Set Attribute's value.
$this->attributes['user_id'] = Auth::id();
}
}
