我无法过滤订单的产品供应商

Question

我希望特殊用户（供应商）在他们的 django 管理中看到他们自己的订单。每当我尝试过滤掉订购产品的用户时。这是代码。我在我的产品模型中连接了供应商。我不知道如何将供应商与他们各自的订单联系起来。

class Order(models.Model):
    STATUS = (
        ('New', 'New'),
        ('Accepted', 'Accepted'),
        ('Preparing', 'Preparing'),
        ('OnShipping', 'OnShipping'),
        ('Completed', 'Completed'),
        ('Canceled', 'Canceled'),
    )
    user = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
    code = models.CharField(max_length=5, editable=False)
    first_name = models.CharField(max_length=10)
    last_name = models.CharField(max_length=10)
    phone = models.CharField(blank=True, max_length=20)
    address = models.CharField(blank=True, max_length=150)
    city = models.CharField(blank=True, max_length=20)
    country = models.CharField(blank=True, max_length=20)
    total = models.FloatField()
    status=models.CharField(max_length=10,choices=STATUS,default='New')
    ip = models.CharField(blank=True, max_length=20)
    adminnote = models.CharField(blank=True, max_length=100)
    create_at=models.DateTimeField(auto_now_add=True)
    update_at=models.DateTimeField(auto_now=True)

class OrderProduct(models.Model):
    STATUS = (
        ('New', 'New'),
        ('Accepted', 'Accepted'),
        ('Canceled', 'Canceled'),
    )
    order = models.ForeignKey(Order, on_delete=models.CASCADE)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    product = models.ForeignKey(Product, on_delete=models.CASCADE)
    variant = models.ForeignKey(Variants, on_delete=models.SET_NULL,blank=True, null=True) # relation with variant
    quantity = models.IntegerField()
    price = models.FloatField()
    amount = models.FloatField()
    status = models.CharField(max_length=10, choices=STATUS, default='New')
    create_at = models.DateTimeField(auto_now_add=True)
    update_at = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.product.title

class OrderAdmin(admin.ModelAdmin):
    list_display = ['first_name', 'last_name','phone','city','total','status','create_at']
    list_filter = ['status']
    readonly_fields = ('user','address','city','country','phone','first_name','ip', 'last_name','phone','city','total')
    can_delete = False
    inlines = [OrderProductline]

class OrderProductAdmin(admin.ModelAdmin):
    list_display = ['user', 'product','price','quantity','amount']
    list_filter = ['product']

    def get_queryset(self, request):
        qs = super().get_queryset(request)
        if request.user.is_superuser:
            return qs
        return qs.filter(product=request.product)```

更改您的 ModelAdmin 子类：

class OrderProductAdmin(admin.ModelAdmin):
    list_display = ['user', 'product','price','quantity','amount']
    list_filter = ['product']

    def get_queryset(self, request):
        return super().get_queryset(request).filter(product__user=request.user)
