Why does hasOneThrough display inappropriate data? - php

Question

In this example, I get a valid array, but with a nested array that has inconsistencies
{ "order_id": 1, "status": 20,
"product_id": [
{ "id": 1, "order_id": 1, "product_id": 8, "quantity": 1, "price": 141 },
{ "id": 2, "order_id": 1, "product_id": 30, "quantity": 2, "price": 509 },
{ "id": 3, "order_id": 1, "product_id": 21, "quantity": 1, "price": 399 } ],
"name": { "id": 1, "name": "Product_1", ... "laravel_through_key": 1 }
since there are three products in the first order, in the second order I already get "name": "Product_4" i.e. the interval is correct, and the order is in the order of the prods table, not in the order_products table:
{ "order_id": 2, "status": 10,
"product_id": [
{ "id": 4, "order_id": 2, "product_id": 1, "quantity": 3, "price": 320 },
{ "id": 5, "order_id": 2, "product_id": 11, "quantity": 2, "price": 953 },
{ "id": 6, "order_id": 2, "product_id": 20, "quantity": 1, "price": 911 } ],
"name": { "id": 4, "name": "Product_4", ... "laravel_through_key": 2 }
How can I make the product names correspond to product_id in order_products?
here is my table diagram:
orders
id - integer
status - integer
order_products
id - integer
order_id - integer
product_id - integer
quantity - integer
price - integer
prods
id - integer
name - string
model Order
class Order extends Model
{
public function order_product()
{
return $this->hasMany('App\Order_product');
}
public function prod()
{
return $this->hasOneThrough('App\Prod', 'App\Order_product', 'order_id', 'id', 'id' );
}
model Prod
class Prod extends Model
{
public function order()
{
return $this->hasMany('App\Order', 'order_products');
}
модель Order_product
class Order_product extends Model
{
protected $fillable = ['order_id', 'product_id', 'quantity', 'price'];
}
Resource Order
class Order extends JsonResource
{
public function toArray($request)
{
return [
'order_id' => $this->id,
'status' => $this->status,
'product_id' => $this->order_product,
'name' => $this->prod,
];
}
controller Order
class OrderController extends Controller
{
public function index()
{
$orders = Order::with(['order_product', 'prod'])->get();
return OrderResource::collection($orders);
}
}

As per your DB design, it suppose to be belongsToMany between order, and product.
Order model
public function products()
{
return $this->belongsToMany('App\Prod', 'Order_product', 'order_id','product_id');
}
Product Model
public function orders()
{
return $this->belongsToMany('App\Order', 'Order_product','product_id', 'order_id');
}
