Eloquent input without relations on 3 table

I have 3 table.

• Quotation (relation with Order)
• Order (relation with Quotation & Project)
• Project (relation with Order, but have no relation with Quotation)

My Model is like
Quotation Model

class Quotation extends BaseModel implements Notifiable
{    public function orders()
     {
       return $this->hasMany(Order::class, 'quotation_id');
     }
}

Order Model

class Order extends BaseModel implements Notifiable
{
    public function quotation()
    {
       return $this->belongsTo(Quotation::class, 'quotation_id');
    }

    public function project()
    {
        return $this->belongsTo(Project::class, 'project_id');
    }
}

Project Model

class Project extends BaseModel
{
    public function order()
    {
    return $this->hasOne(Order::class, 'project_id');
    }
}

I want when i create project, its filled to project_id for every order table in same quotation (with eloquent). is that possible?

My current controller like this

    public function store(ProjectRequest $request, Order $order, $number = null)
    {
        if (!$number) {
            $number = numbering(new Project(), 'PRJ');
        }

        $project = Project::create($request->data($number));

        $order->project()->associate($project)->save();

        return \response([
            'path' => "/projects/$project->id"
        ]);
    }

But it just filled project_id just in one order row.
