Django를 사용하지만 0에서 프로젝트를 시작하는 방법을 모르겠습니다. 다음은 내 코드입니다.
view.py :
from django.shortcuts import render
from django.http import HttpResponse
from rest_framework import viewsets
from rest_framework.response import Response
from .models import Product
from .serializers import ProductListSerializer
class ProductViewSet(viewsets.ModelViewSet):
lookup_field = 'pk'
model = Product
queryset = Product.objects.all()
serializer_class = ProductListSerializer
urls.py
from django.urls import path
from . import views
import product.views as v
product_detail = v.ProductViewSet.as_view({'get': 'retrieve',
'delete': 'destroy',
'patch': 'partial_update'})
product_list = v.ProductViewSet.as_view({'post': 'create', 'get': 'list'})
urlpatterns = [
path('products/<int:pk>', product_detail),
path('products', product_list),
]
models.py
from django.db import models
# Create your models here.
class Product(models.Model):
class Meta:
app_label = 'product'
index_together = [
['title'],
]
title = models.CharField(max_length=150)
def __str__(self):
return '(Product)%s' % self.title
serializers.py
from .models import Product
class ProductListSerializer():
class Meta:
model = Product
fields = ['title']
이미 마이그레이션을 수행하고 마이그레이션합니다. 내 DB에 데이터가 없지만 요청 URL의 응답은 항목이 0 인 응답이어야합니다. 내가 뭔가 잘못했거나 중요한 것을 잊었습니까?
직렬 변환기 클래스가 누락되었습니다.
이 시도
from .models import Product
from rest_framework import serializers
class ProductListSerializer(serializers.ModelSerializer):
