django - 'User' 类型的 DRF 对象不是 JSON 可序列化的

Question

我试图通过以下方式返回当前登录用户的详细信息:

from .serializers import UserSerializer

class UserDetailsView(RetrieveAPIView):                                                                                                                                                                           
    model = User                                                                                                                                                                                                  
    queryset = User.objects.all()                                                                                                                                                                                 
    permission_classes = [permissions.IsAuthenticated]                                                                                                                                                            
    serializer_class = UserSerializer                                                                                                                                                                             

    def get(self, request, *args, **kwargs):                                                                                                                                                                      
        user = User.objects.get(id=request.user.id)                                                                                                                                                               
        print(user)                                                                                                                                                                                               
        return Response(user)

在 serializers.py 中我使用了 ModelSerializer

class UserSerializer(serializers.ModelSerializer):                                                                                                                                                                
      password = serializers.CharField(write_only=True)                                                                                                                                                             

      def create(self, validated_data):                                                                                                                                                                             
          user = UserModel.objects.create(username=validated_data['username'])                                                                                                                                      
          user.set_password(validated_data['password'])                                                                                                                                                             
          user.save()                                                                                                                                                                                               
          return user                                                                                                                                                                                               

      class Meta:                                                                                                                                                                                                   
          model = UserModel                                                                                                                                                                                         
          fields = ('id', 'username', 'password')                                                                                                                                                                   
          write_only_fields = ('password',)

我收到一个错误 Object of type 'User' is not JSON serializable .我的用例有什么问题？

你需要返回

return Response(serializer.data)

在 UserDetailsView 下的 get 函数中。更多详情here .
