Laravel doesn't return relation id into child table (One To One Relationship)

Question

Im about to make Create Model Eloquent by having two table (one to one relationship) Task a parent to E-katalog as a child. But it doesn't work for my relation id(task_id) in my Ekatalog table

this is my Tables looks like

Task

   id
   title

E-Katalog

   id
   type
   task_id

My migrations :

Schema::create('tasks', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->timestamps();
}

Schema::create('ekatalogs', function (Blueprint $table) {
            $table->id();
            $table->foreignId('task_id')->nullable(),
            $table->string('type');
            ->nullable();
}

Relation in Model in my Task:

public function ekatalog(){
        return $this->hasOne(Ekatalog::class);
    }

Controller :

  //validation
  $taskData = $request->validate([
            'title' => 'required|max:255']);
  $ekatalogData =  $request->validate([
            'type' => 'max:255']);
  //create 
  $task->create($taskData);
  $task->ekatalog()->create($ekatalogData);

the code is working, but task_id in my Ekatalog is null. i thought it automatically make or generate value id by itself from parent's id(Task). How can i make it work?

$task->create($taskData) will create a new object instance. Try this:

 //validation
  $taskData = $request->validate([
            'title' => 'required|max:255']);
  $ekatalogData =  $request->validate([
            'type' => 'max:255']);
  //create 
  $task = Task::create($taskData);
  $task->ekatalog()->create($ekatalogData);
