Когда я создаю нового пользователя, соответствующий BaseUser не создается. Сигнал работает правильно, так как я проверил без атрибутов department и user_type как мне прописать BaseUser?
# models.py
from django.db import models
from django.conf import settings
from django.contrib.auth.models import User
class BaseUser(models.Model):
# TODO: Add a class with static method to return the list of departments(choices)
# TODO: (REMINDER) To add placeholder that username is rollnumber
USER_TYPES = (
(0, 'Student'),
(1, 'Professor'),
(2, 'Guest'),
)
user = models.OneToOneField(User, primary_key=True,
related_name='user')
department = models.CharField(max_length=3, default='CSE')
user_type = models.IntegerField(choices=USER_TYPES, default=0)
REQUIRED_FIELDS = [
'department',
'email',
'first_name',
'user_type'
]
def get_user_type(self):
return self.USER_TYPES[self.user_type][1]
def __unicode__(self):
return str(
dict((
self.user.user_name,
self.get_user_type(),
))
)
# serializers.py
from django.contrib.auth.models import User
from rest_framework import serializers
from authentication.models import BaseUser

class Meta:
model = User
fields = (
'id',
'username',
'first_name',
'email'
)
class BaseUserSerializer(serializers.ModelSerializer):
user = UserSerializer()
user_type = serializers.SerializerMethodField()
class Meta:
model = BaseUser
fields = (
'user',

def get_user_type(self, obj):

class UserViewSet(viewsets.ModelViewSet):

EDIT: я пытался следовать этому подход, но я получил сообщение об ошибке, что у пользователя нет этих атрибутов (т.е. 'Some fields are empty!'

# I have another signal in signals.py and it is working fine.
