自動一個 User class

python manager startapp user

繼承 user class 可以自行擴展

# vim user.models

from django.contrib.auth.models import AbstractUser

#Createyourmodelshere.
classUser(AbstractUser):
  pass

建立 signals.py

# vim user.signals

from django.dispatch import receiver
from django.db.models.signals import post_save
from django.conf import settings
from django.contrib.auth.models import Group

@receiver(post_save, sender=settings.AUTH_USER_MODEL)
def auto_grant_group(sender, **kwargs):
   user = kwargs['instance']
   if kwargs["created"]:
       if not user.is_superuser:
           user.is_staff = True
           try:
               g = Group.objects.get(name='view_only')
               g.user_set.add(user)
           except Group.DoesNotExist:
               # print info
               print("group 不存在")
           user.save()

註冊 signals

# vim user.apps

from django.apps import AppConfig
from django.db.models.signals import post_save
from django.conf import settings

class UserConfig(AppConfig):
   name = 'user'

   def ready(self):
       # signals are imported, so that they are defined and can be used
       from user.signals import auto_grant_group

在 settings 註冊新的 user class

# vim settings

INSTALLED_APPS = [
   'django.contrib.admin',
   'django.contrib.auth',
   'django.contrib.contenttypes',
   'django.contrib.sessions',
   'django.contrib.messages',
   'django.contrib.staticfiles',
   'django.contrib.sites',
   'user.apps.UserConfig',
]

AUTH_USER_MODEL = 'user.User'
