Laravel : How return nested JSON from models - php

Question

I have an app contain many tables :
products table , order table , order_items table.
I made models for all of them as below :
class Product extends Model
{
use HasFactory;
protected $fillable = [
'product_name',
'category_id',
'price',
'sale',
'counter',
'isfavore'
];
public function Order_item()
{
return $this->hasMany('App\Models\Order_item');
}
public function category()
{
return $this->belongsTo('App\Models\Category' ,'category_id');
}
}
class Order extends Model
{
use HasFactory;
protected $fillable = [
'user_id',
'status',
];
public function order_item()
{
return $this->hasMany('App\Models\Order_item');
}
public function user()
{
return $this->belongsTo('App\Models\User' ,'user_id');
}
}
class Order_item extends Model
{
use HasFactory;
protected $fillable = [
'order_id',
'product_id',
'quantity',
];
public function order()
{
return $this->belongsTo('App\Models\Order' ,'order_id');
}
public function product()
{
return $this->belongsTo('App\Models\Product' ,'product_id');
}
}
I want to display details like below depend on order_id :
{
"id": 7,
"user_id": 23,
"status": "ordered",
"order_item": [
{
"id": 30,
"order_id": 7,
"product_id": 5,
"quantity": 1,
"product_name" : "banana", //-----------------------want to add from product model
"price" : "2000" //-----------------------want to add from product model
},
{
"id": 31,
"order_id": 7,
"product_id": 1,
"quantity": 1,
"product_name" : "apple",
"price" : "1500"
}
]
}
I create this controller which show same result above without product name and price:
public function get_order($id){
$order=Order::find($id);
$order->order_item;
return $order;
}
Now just I need to add product name and price from product model ,How can I do that?

Answer 1

You have to load the relationships.
Try this:
public function get_order($id){
$order=Order::find($id);
$order_items = Order_item::with('product')->where('order_id',$id)->get();
return $order;
}

Answer 2

I get best answer from #Develope and #danish-khan-I ,just change controller to :
public function get_order($id){
$order=Order::with('order_item.product')->find($id);
return $order;
}
