如何在一個請求中放置或刪除多個對象？ 姜戈休息

Question

它允許我在 make def create 之后傳入 json 格式的數據來發布以創建記錄，以便像 [{data:data,data:data}] 這樣的 json 格式可以發布。我應該怎么做，以便我也可以 make put在一個請求中請求多個對象還是使用 post 方法更新？

下面是views.py。

from django.shortcuts import render

from .models import ListForm

# Create your views here.
from rest_framework import viewsets
from .serializers import ListFormSerializer
from rest_framework import filters
import django_filters.rest_framework

from rest_framework.response import Response
from rest_framework import status, viewsets

class ListFormViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows users to be viewed or edited.
    """
    queryset = ListForm.objects.all().order_by('group')
    serializer_class = ListFormSerializer
    filter_backends = (django_filters.rest_framework.DjangoFilterBackend, filters.SearchFilter, filters.OrderingFilter,)
    filterset_fields = ['group','key_description'] 
    search_fields = ['group']

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data, many=isinstance(request.data,list))
        serializer.is_valid(raise_exception=True)
        self.perform_create(serializer)
        headers = self.get_success_headers(serializer.data)

        queryset = self.filter_queryset(self.get_queryset()) 
        page = self.paginate_queryset(queryset) 
        if page is not None: 
            serializer = self.get_serializer(page, many=True)

            return self.get_paginated_response(serializer.data)

            serializer = self.get_serializer(queryset, many=True)

            return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)

        # return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)

也許你需要這樣的東西：

from rest_framework import viewsets
from rest_framework.response import Response
from rest_framework.decorators import action

import json
from .models import Post
from .serializers import PostSerializer

class PostViewSet(viewsets.ModelViewSet):
    
    queryset = Post.objects.none()
    serializer_class = serializers.PostSerializer

    @action(detail=False, methods=['post'])
    def update_this(self, request):

        try:
            data = json.loads(request.data)
        except:
            try:
                data = dict(request.data)
            except:
                data = request.data

        # You can do everything you want here with data

        return Response({'code': 0, 'desc': 'OK', 'more_data': {}})
