Django JWT - 向用户添加自定义字段

Question

我想向 JWT 用户模型添加一个自定义字段，例如传记并使用 API 获取。我无法处理它，我很困惑。我收到此错误“django.core.exceptions.ImproperlyConfigured: Field name bio is not valid for model User.”

我的models.py如下：

from django.core.validators import MinValueValidator, MaxValueValidator
from django.db import models
from django.db.models.signals import post_save
from rest_framework_jwt.serializers import User
from tinymce.models import HTMLField



class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    bio = models.TextField(max_length=500, blank=True)

Views.py

from rest_framework import viewsets, status, permissions
from rest_framework.response import Response
from rest_framework.authentication import TokenAuthentication
from rest_framework.views import APIView
from rest_framework.permissions import IsAuthenticated, AllowAny
from django.contrib.auth.models import User
from rest_framework.decorators import action, api_view
from .serializers import UserSerializer, UserSerializerWithToken


@api_view(['GET'])
def current_user(request):
    """
    Determine the current user by their token, and return their data
    """

    serializer = UserSerializer(request.user)
    return Response(serializer.data)


class UserList(APIView):
    """
    Create a new user. It's called 'UserList' because normally we'd have a get
    method here too, for retrieving a list of all User objects.
    """

    permission_classes = (permissions.AllowAny,)

    def post(self, request, format=None):
        serializer = UserSerializerWithToken(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

Serializers.py

from rest_framework_jwt.serializers import User

from .models import Content, Rating
from rest_framework import serializers
from rest_framework_jwt.settings import api_settings


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


class UserSerializerWithToken(serializers.ModelSerializer):

    token = serializers.SerializerMethodField()
    password = serializers.CharField(write_only=True)

    def get_token(self, obj):
        jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER
        jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER

        payload = jwt_payload_handler(obj)
        token = jwt_encode_handler(payload)
        return token

    def create(self, validated_data):
        password = validated_data.pop('password', None)
        instance = self.Meta.model(**validated_data)
        if password is not None:
            instance.set_password(password)
        instance.save()
        return instance

    class Meta:
        model = User
        fields = ('token', 'username', 'password', 'bio')
