我在 Django 中設定了以下簡單的 rest api。呼叫urlhttp://127.0.0.1:8000/listheros/回傳
TypeError：英雄型別的物件不是 JSON 可序列化的
出于某種原因，我似乎無法弄清楚。
# views.py
from rest_framework.views import APIView
from rest_framework.response import Response
from .serializers import HeroSerializer
from .models import Hero
class ListHeros(APIView):
def get(self, request, format=None):
"""
Return a list of all users.
"""
queryset = Hero.objects.all().order_by('name')
serializer_class = HeroSerializer
print('get')
return Response(queryset)
# urls.py
from django.urls import include, path
from applications.api.views import ListHeros
urlpatterns = [
path('listheros/', ListHeros.as_view()),
path('api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]
# serializers.py
from rest_framework import serializers
from .models import Hero
class HeroSerializer(serializers.ModelSerializer):
class Meta:
model = Hero
fields = ('name', 'alias')
# models.py
from django.db import models
class Hero(models.Model):
name = models.CharField(max_length=60)
alias = models.CharField(max_length=60)
def __str__(self):
return self.name
uj5u.com熱心網友回復：
您不會序列化您的英雄查詢集。您的 ListHeroes api 視圖應如下所示：
class ListHeros(APIView):
def get(self, request, format=None):
"""
Return a list of all users.
"""
queryset = Hero.objects.all().order_by('name')
serializer = HeroSerializer(queryset, many=True)
return Response(serializer.data)
您還可以使用泛型 ListApiView 代替 APIView：
from rest_framework.generics import ListAPIView
class ListHeros(ListAPIView):
queryset = Hero.objects.all().order_by('name')
serializer_class = HeroSerializer
