我在数据库中有三个表。 orders, products
和order_product
表。这就是他们在我的phpmyAdmin
https://imgur.com/a/Ud9e2Hh中的样子
我希望卖方能看到买方在他们看来(dashboard
所下的订单。此外,买家还可以在其视图中查看其订单。
这是我在模型中的关系
User.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;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'name', 'email', 'password', 'Seller'
];
/**
* The attributes that should be hidden for arrays.
*
* @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');
}
}
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');
}
}
卖方功能
// Seller Orders
public function viewOrders(User $user)
{
// $products = Products_model::where('seller_id', '=', $user->id)->get();
// all sells
$sells = $user->orderFromSellers();
dd($sells);
return view('orders')->with(compact('sells'));
}
买方功能
//Buyer Orders
public function myOrders()
{
$cart = session();
$orders = Auth::user()->orders;
$orders->transform(function($order, $key) {
dd($orders);
$order->cart = unserialize($order->cart);
return $order;
});
return view('myOrders', ['orders' => $orders]);
}
现在它什么也没显示。对于解决此问题的任何帮助将不胜感激。
Products_model
protected $table='products';
protected $primaryKey='id';
protected $fillable=['seller_id','pro_name','pro_price','pro_info','image','stock','category_id '];

尝试通过更改两个功能。
public function orderFromBuyers()
{
return $this->hasManyThrough(Products_model::class, OrderProduct::class, 'buyer_id', 'product_id');
}
public function orderFromSellers()
{
return $this->hasManyThrough(Products_model::class, OrderProduct::class, 'seller_id', 'product_id');
}
否则两者会更好。将这两个功能添加到用户模型。
public function allOrderFromBuyers()
{
return $this->hasMany(OrderProduct::class, 'buyer_id');
}
public function allOrderFromSellers()
{
return $this->hasMany(OrderProduct::class, 'seller_id');
}
然后将其更改为
// Seller Orders
public function viewOrders(User $user)
{
// all sells
$sells = $user->allOrderFromSellers();
dd($sells);
return view('orders')->with(compact('sells'));
}
