У меня проблемы с тем, как справляться с отношениями таблиц в laravel.У меня есть три таблицы Таблица заказов, таблица Order_product и таблица пользователей.Пользователь может быть описан как продавец или покупатель, в зависимости от того, что они перечислили или купили что-то.Теперь, когда пользователь отправляет форму заказа, я получаю сообщение об ошибке
"Общая ошибка: 1364 Поле 'seller_id' не имеет значения по умолчанию (SQL: вставить в order_product (order_id, product_id,quantity, `up ▶"
Вот как эти таблицы выглядят в phpmyAdmin

Ниже приведены модели
Пользователь.php
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use Notifiable;
/**

protected $fillable = [
'name', 'email', 'password', 'Seller'
];
/**

*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
//public function isSeller() {
// return $this->seller;
//}
public function products()
{
return $this->hasMany(Products_model::class);
}
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
public function orders()
{
return $this->hasManyThrough(Order::class, Products_model::class, 'buyer_id', 'seller_id', 'product_id');
}
public function orderFromBuyers()
{
return $this->hasManyThrough(OrderProduct::class, Products_model::class, 'buyer_id', 'product_id');
}
public function orderFromSellers()
{
return $this->hasManyThrough(OrderProduct::class, Products_model::class, 'seller_id', 'product_id');
}
}
Products_model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class products_model extends Model
{
protected $table='products';
protected $primaryKey='id';
protected $fillable= ['seller_id','pro_name','pro_price','pro_info','image','stock','category_id'];
}
OrderProduct.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class OrderProduct extends Model
{
protected $table = 'order_product';
protected $fillable = ['order_id', 'buyer_id', 'seller_id','product_id', 'quantity'];
public function products()
{
return $this->belongsTo('App\Products_model');
}
public function buyer()
{
return $this->belongsTo(User::class, 'id', 'buyer_id');
}
public function seller()
{
return $this->belongsTo(User::class, 'id', 'seller_id');
}
public function order()
{
return $this->belongsTo(Order::class);
}
}
Order.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Order extends Model
{
//protected $table = 'orders';
protected $fillable = [
'shipping_email', 'shipping_name', 'shipping_city', 'shipping_phone', 'billing_subtotal', 'billing_total',
];
public function user()
{
return $this->belongsTo('App\User');
}
public function products()
{
return $this->belongsToMany('App\Products_model')->withPivot('quantity');
}
public function orders(){
return $this->hasMany('App\OrderProduct', 'order_id');
}
}
Вот мой магазин функция
public function store(Request $request)
{
//Insert into orders table
$order = Order::create([
'buyer_id' => auth()->user() ? auth()->user()->id : null,
'shipping_email' => $request->email,
'shipping_name' => $request->name,
'shipping_city' => $request->city,
'shipping_phone' => $request->phone,
// 'error' => null,
]);
//Insert into order product table
if ($order) {
foreach(session('cart') as $productId =>$item) {
if (empty($item)) {
continue;
}
OrderProduct::create([
'order_id' => $order->id ?? null,
'product_id' => $productId,
// $products=DB::table('products')->where('id',$id)->get();
'quantity' => $item['quantity'],
//dd($item)
]);
}
}
//Empty Cart After order created
$cart = session()->remove('cart');
return redirect()->route('confirmation.index')->with('success_message', 'Thank you! Your payment has been successfully accepted!');
}
