python - 在django中将序列化数据转换为字典

Question

我尝试在 Django 中序列化用户数据，但后来我想将其作为字典打印在控制台中，它给了我一个空字典，我该如何处理。

序列化器.py

from rest_framework import routers, serializers, viewsets
from accounts.models import User



class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = 'username', 'email', 'first_name', 'last_name', 'date_joined'

View .py

from django.shortcuts import render
from rest_framework.generics import  ListAPIView
from rest_framework.response import Response
from .serialize import UserSerializer




import json



class userApi(ListAPIView):
    def get(self, request):
        queryset = User.objects.all()
        serializer_class = UserSerializer(queryset, many=True)
        return Response(serializer_class.data)

apiuser=userApi()
point = json.dumps(apiuser.__dict__)


print(point)

控制台

Watching for file changes with StatReloader

**{}**#This is what it is printing

Serializers默认返回字典，所以如果要在控制台打印序列化后的数据，必须在view的get方法中打印。像这样:

class userApi(ListAPIView):
    def get(self, request):
        queryset = User.objects.all()
        serializer_class = UserSerializer(queryset, many=True)
        print(serializer_class.data)
        return Response(serializer_class.data)

然后像这样为 View 设置一个 url:

path('users/', userApi.as_view())

当您在浏览器中打开此 url 或向其发送 get 请求时，序列化数据将打印在控制台中。
