=> ShopProduct 모델의 category는 foreign key이기 때문에 ShopCategory의 인스턴스여야 한다는 

 

해당 부분 수정하고 다시 돌렸음

 - cls.product_data = {'product_name':"test111", 'product_desc':"ddd", 'category':cls.category.id} 추가

또 에러났던 원인.. 

    def get_absolute_url(self):
        return reverse('product_view', kwargs={"category_id": self.id})

해당 absolute_url을 잘 못 주고 있었다
