☄️ 현재까지 프로젝트 진행 순서(Backend)
- Django 초기세팅
- ERD
- models.py 작성후 migration (User, Product)
- views.py (Signup, Login, Productlist, Productdetail)
signup, login view는 instagram clone project에서 해봤기 때문에 수월하게 진행 되었는데, Product 관련 view는 처음이다보니 시간도 걸리고 모델링 수정도 많이 하게 되었다.
🙋♀️ Productlist, Productdetail
첫 번째 도전의! 코드!

(통신만을 위한 코드 / 주석처리하고 FE와 통신만 맞춰보았다.)

status = 200)🤔 product category 카테고리
필요한 페이지라고 생각해 view를 짰는데 .. 착각했던 페이지였다.
FE 와의 소통이 매우 중요하다는 것을 다시 한 번 느꼈다.
class MainCategoryListView(View):
def get(self, request, product_id):
try:
product = Product.objects.select_related('category', 'alcohol_type').get(id=product_id)
category = Category.objects.all()

category_image = CategoryImage.objects.all()
products_image = ProductImage.objects.all()
category_list = [{
'category_image' : category_image.image_url,
'category' : category.name
}]
product_list = [{
'id' : products.id,
'name' : products.name,
'price' : products.price,

}]
except ValueError:
return JsonResponse({'message': 'VALUE_ERROR'}, status = 400)
return JsonResponse({

닫혀 있어서 벽인 줄 알고 있지만, 사실은 문이다.
