Laravel get attribute with hasMany - php

Question

I'm making shop online with Laravel. I made Cart with records user_id and product_id with relations hasMany to products. My problem is that I can't get for example product's name or price, I can only get whole array with products and cart data. Can someone tell me how to get it? Maybe there is a problem with a query or just view syntax.
My migration:
public function up()
{
Schema::create('carts', function (Blueprint $table) {
$table->id();
$table->unsignedBigInteger('user_id');
$table->unsignedBigInteger('product_id');
$table->timestamps();
$table->foreign('user_id')->references('id')->on('users');
$table->foreign('product_id')->references('id')->on('products');
});
Here is my controller function:
public function index(Request $request)
{
$query = Cart::with('product')->where('carts.user_id', $request->user()->id);
$query = $query->get();
return view('cart.index', ['cart' => $query]);
}
And view to show cart
#extends('app')
#section('content')
#foreach ($cart as $item)
<form method="" action="{{ route('destroycart', ['id' => $item->id]) }}">
{{ $item['product'] }}
<button class="btn btn-outline-dark">X</button>
</form>
#endforeach
#endsection
Model:
class Cart extends Model
{
use HasFactory;
public function product() {
return $this->hasMany(Product::class, 'id', 'product_id');
}
}
Is there another option for $item['product'] to get only product data?
Forgot to paste what view returns:
[{"id":10,"name":"lklkl","description":"klklkk","img":"przyklad.mo.jpg","price":50,"count":9,"created_at":"2022-05-24T13:13:03.000000Z","updated_at":"2022-05-24T13:13:03.000000Z"}]
I would like to get for example product's name.

Answer 1

You should then also access products, so:
#foreach ($cart as $item)
// Cart stuff here.
#foreach ($item->product as $prod)
// Product stuff here
#endforeach
#endforeach

Answer 2

You can get a single cart in the controller method if you want to display only one cart at a time
public function index(Request $request)
{
return view('cart.index', [
'cart' => Cart::with('product')
->where('user_id', $request->user()->id)
->latest()
->first()
]);
}
Then in your view you can loop over the products in the cart
#extends('app')
#section('content')
<form method="" action="{{ route('destroycart', ['id' => $cart->id]) }}">
#foreach ($cart->product as $product)
<p>{{ $product->name }}</p>
#endforeach
<button class="btn btn-outline-dark">X</button>
</form>
#endsection
Or if you want to show all carts for the currently logged in user then you can do it as
public function index(Request $request)
{
return view('cart.index', [
'carts' => Cart::with('product')
->where('user_id', $request->user()->id)
->latest()
->get()
]);
}
The in the view loop over the carts and with each iteration - loop over the products
#extends('app')
#section('content')
#foreach($carts as $cart)
<form method="" action="{{ route('destroycart', ['id' => $cart->id]) }}">
#foreach ($cart->product as $product)
<p>{{ $product->name }}</p>
#endforeach
<button class="btn btn-outline-dark">X</button>
</form>
#endforeach
#endsection
