Django Rest框架- ListCreateAPIView不打印任何内容
Django Rest框架- ListCreateAPIView不打印任何内容
提问于 2019-03-14 15:58:10
我使用django rest框架创建了一个API for list和create。但是它不能打印Web browsable api中的任何内容。我不知道问题出在哪里。当我打印queryset和serializer变量时，它给出了作为QuerySet的正确输出。为什么会发生这种情况？
Views.py
from rest_framework.response import Response
from rest_framework import generics
from .serializers import MovieSerializer
from movie.models import Movie
from rest_framework.permissions import IsAuthenticated
class MovieList(generics.ListCreateAPIView):
queryset = Movie.objects.all()[:10]
serializer_class = MovieSerializer
permission_classes = (IsAuthenticated,)
def list(self, request):
# Note the use of `get_queryset()` instead of `self.queryset`
queryset = self.get_queryset()
# print(queryset)
serializer = MovieSerializer(queryset, many=True)
# print(serializer.data)
return Response(serializer.data)Serializers.py
from rest_framework import serializers
from movie.models import Movie
class MovieSerializer(serializers.Serializer):
class Meta:
model = Movie
fields = [
'popularity',
'director',
'genre',
'imdb_score',
'name',
]请参阅图片以供参考。

问题出在您的serializers.py中。您必须使用ModelSerializer而不是Serializer。
from rest_framework import serializers
from movie.models import Movie
class MovieSerializer(serializers.ModelSerializer): # <-
class Meta:
model = Movie
fields = [
'popularity',
'director',
'genre',
'imdb_score',
'name',
