Laravel Custom Model Class - Field Does not have a Default Value - php

Question

So, I have a custom Model extension class called RecursiveModel:
use Illuminate\Database\Eloquent\Model;
use ... RecursiveHelper;
class RecursiveModel extends Model {
private $recursiveHelper = null;
public function __construct(){
$this->recursiveHelper = new RecursiveHelper();
parent::__construct();
}
public function save(array $options = []){
parent::save($options);
}
...
// Additional methods available for Recursive Models (self-referenced `parent_id` relationships)
}
And, a Model that extends this RecursiveModel class instead of the base Model class:
use ... RecursiveModel;
use Illuminate\Database\Eloquent\SoftDeletes;
class Line extends RecursiveModel {
use SoftDeletes;
protected $table = "lines";
protected $primaryKey = "id";
public function parent(){
return $this->belongsTo(self::class, "parent_id", "id");
}
public function children(){
return $this->hasMany(self::class, "parent_id", "id");
}
}
All is well and good, and with previously imported records (back when Line extended Model and not RecursiveModel, I was able to use my RecursiveHelper methods/logic without issue. Now, I'm trying to refresh my database, which calls a Seeder:
use Illuminate\Database\Seeder;
use ... Slugger;
use ... Line;
class LinesSeeder extends Seeder {
public function run(){
$parentLine = Line::create([
"name" => "Line Item",
"slug" => $this->slugger->slugify("Line Item"),
"created_at" => date("Y-m-d H:i:s"),
"updated_at" => date("Y-m-d H:i:s"),
]);
$childLine = Line::create([
"name" => "Child Line Item",
"slug" => $this->slugger->slugify("Child Line Item"),
"parent_id" => $parentLine->id,
"created_at" => date("Y-m-d H:i:s"),
"updated_at" => date("Y-m-d H:i:s"),
]);
...
}
}
As previously stated, when Line extended Model and not RecursiveModel, this code worked without issue. But now, I'm running into this error:
SQLSTATE[HY000]: General error: 1364 Field 'name' doesn't have a default value (SQL: insert into lines
(updated_at, created_at) values (2018-08-13 15:56:45, 2018-08-13 15:56:45))
The Line::create([...]); doesn't seem to be receiving the parameter passed; is there something I'm missing when extending Model.php? I've tried adding:
public function create(array $options = []){
parent::create($options);
}
To RecursiveModel, but that just throws another error (and I don't think the create() method is a part of Model.php, but rather Builder.php.)
Also, it's not an issue with protected $fillable, nor is it an issue with setting 'strict' => true, on my mysql connection; already tried both of those to no avail.
As suggested, updated __construct method of RecursiveModel to:
public function __construct(array $attributes = []){
$this->recursiveHelper = new RecursiveHelper();
return parent::__construct($attributes);
}
Unfortunately, still getting the same error.
Edit: Line.php had a __construct method that was carried over from when I was applying $this->recursiveHelper model by model; solution was to update signature to match (as noted above) or remove __construct from extending models.

Model constructors need to take in an array of attributes:
public function __construct(array $attributes = [])
