Junior User 继承自自定义 User model

class ListCreateUserProfile(generics.ListCreateAPIView):
    queryset = JuniorUser.objects.all()
    serializer_class = JuniorProfileSerializer

    location = LocationSerializer(read_only=True, many=True)
    language = serializers.MultipleChoiceField(choices=LANGUAGE)
    work_experience = ExperienceSerializer(read_only=True, many=True)
    education = EducationSerializer(read_only=True, many=True)
    course = CourseSerializer(read_only=True, many=True)

    class Meta:
        model = JuniorUser
        fields = ['id', 'terms_is_accepted', 'first_name', 'last_name',
                  'phone_number', 'telegram_nick', 'linkedin', 'location',
