Как исправить ошибочный поиск ключа при разрешении метода доступа в проекте django

Я изменил на python 3.5.2. Я использую django_tables2 и сталкиваюсь с проблемой Failed lookup for key [wholesale_product] in {'wholesale_product__code': '11500356', 'quantity': Decimal('1.00'), 'wholesale_product__description': 'ΜΕΤΡΟΤΑΙΝΙΑ IRWIN 5M SHORT', 'wholesale_product__id': 76970}, when resolving the accessor wholesale_product__id

Проблема связана с полем оптового продукта, которое является FK для моей модели Warehouse_Order_Backorder.

моя модель 

class Warehouse_Order_Backorder(models.Model):
    woo_order = models.ForeignKey(Woo_Orders,verbose_name="Παραγγελία Χοντρικής",null=True,on_delete=models.CASCADE)
    wholesale_product=models.ForeignKey(Product,null=True,on_delete=models.CASCADE)
    warehouse=models.ForeignKey(Warehouse,verbose_name=u'Αποθήκη',blank=True, null=True,on_delete=models.CASCADE)
    quantity = models.DecimalField("Ποσότητα", max_digits=7, decimal_places=2, default=0)
    date = models.DateTimeField("Ημ/νία",null=True, blank=True, default=datetime.datetime.now)



    def __str__(self):
        return self.woo_order.oid+" "+self.wholesale_product.description

мой стол 

class BackOrderTable(tables.Table):

    #description
    wholesale_product_name = tables.Column(accessor='wholesale_product__description',verbose_name= 'Προϊόν που έχει backorder')
    #sku
    wholesale_product_code = tables.Column(accessor='wholesale_product__code',verbose_name= 'Sku Προϊόντος')
    #product_id
    wholesale_product_id = tables.Column(accessor='wholesale_product__id',verbose_name= 'ID Προϊόντος')
    #details button
    details=tables.LinkColumn('backorder_details_list',args=[A('wholesale_product__id')],accessor='Backorder Details',orderable=False,empty_values=(),verbose_name = 'Λεπτομέρειες backorder')



    class Meta:
        #define the model
        model = Warehouse_Order_Backorder
        template_name = 'django_tables2/bootstrap4.html'
        exclude = ('id','date',"warehouse","woo_order",'wholesale_product')
        sequence = ('wholesale_product_name','wholesale_product_code', 'wholesale_product_id',"quantity",'details')


    def render_wholesale_product_id(self,record):
        return '%s' % (record.wholesale_product.id)


    def render_wholesale_product_name(self,record):
        return '%s' % (record.wholesale_product.description)


    def render_wholesale_product_code(self,record):
        return '%s' % (record.wholesale_product.code)

    def render_details(self,record):
        return format_html('<a href="/backorder_details/{}/"><button class="btn btn-primary btn-sm" type="">Details</button></a>',record['wholesale_product__id'])

вот мой Traceback

Есть идеи, что может вызвать ошибку?

Дело в том, что я передал словарь в таблицу, а не набор запросов, поэтому в моей таблице мне пришлось отобразить значение wholesale_product со ссылкой на словарь, как показано ниже: 

def render_wholesale_product_id(self,record):
    return '%s' % (record['wholesale_product_id'])

Вы определяете поле wholesale_product_id в своем классе BackOrderTable. Можете ли вы попробовать переименовать это поле, например, wholesale_productid. Мне интересно, совпадает ли это имя с сгенерированными именами django. См. Этот другой ответ SO: Django запрос одиночного подчеркивания, ведущий себя как двойное подчеркивание? для получения дополнительной информации.
