Question

我使用Django rest框架和python3.5。之前我有另一个版本的python，一切都很顺利。当我想从带有URL的服务器获取一些信息时，例如：

“http://127.0.0.1:8000/api/companies”

我收到错误：

“OrderedDict在迭代期间发生变异”

在views.py中我有：

from django.shortcuts import render
from companies.models import Companies
from companies.serializers import CompaniesSerializer
from rest_framework import generics
from rest_framework.response import Response
from rest_framework.renderers import JSONRenderer
from rest_framework import status


class CompaniesList(generics.ListCreateAPIView):
    queryset = Companies.objects.all()
    serializer_class = CompaniesSerializer


class CompaniesDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Companies.objects.all()
    serializer_class = CompaniesSerializer

我该怎么做才能让它发挥作用？哪些东西会改变字典？

我不知道为什么使用ListCreateApiView改变dict，但是我将类更改为如下函数：

@api_view(['GET'])
    def CompaniesList(request):
        if request.method == 'GET':
            companies = Companies.objects.all()
            serializer = CompaniesSerializer(companies, many=True)
            return Response(serializer.data)

现在它正在运作......
