似乎无法找到明确回答我问题的回复。
如果使用以下基本代码扩展Django用户模型：
employee这对创建新用户有何影响？创建新用户时是否自动创建department类对象？如果需要merge into字段，如何同时创建用户对象和员工对象？

如果您希望在创建应用实例或创建用户时，可以使用django信号，这将在创建新用户时自动创建实例。
from django.db.models.signals import *
from __future__ import unicode_literals
class Employee(models.Model):
userName = models.OneToOneField(User, related_name='profile')
department = models.CharField(max_length=100, null=True)
def __unicode__(self): # __str__
return unicode(self.userName)
def create_user_profile(sender, instance, created, **kwargs):
if created:
Employee.objects.create(userName=instance)
post_save.connect(create_user_profile, sender=User)
这将在创建新用户时自动创建员工实例（之后可以添加空白实例数据）。
如果您希望扩展用户模型并希望在创建用户时添加更多信息，可以使用django-betterforms（http://django-betterforms.readthedocs.io/en/latest/multiform.html）
from django.db.models.signals import *
from __future__ import unicode_literals
class Employee(models.Model):
userName = models.OneToOneField(User, related_name='profile')
department = models.CharField(max_length=100)
def __unicode__(self): # __str__
return unicode(self.userName)
from django import forms
from django.forms import ModelForm
from betterforms.multiform import MultiModelForm
from django.contrib.auth.forms import UserCreationForm
from .models import *
class EmployeeForm(ModelForm):
class Meta:
model = Employee
exclude = ('userName',)
class addEmployeeMultiForm(MultiModelForm):
form_classes = {
'user':UserCreationForm,
'profile':EmployeeForm,
}
from django.views.generic import CreateView
from django.shortcuts import redirect
from .models import *
from .forms import *
class addEmployee(CreateView):
form_class = addEmployeeMultiForm
template_name = "addEmployee.html"
success_url = '/your url after user created'
def form_valid(self, form):
user = form['user'].save()
profile = form['profile'].save(commit=False)
profile.userName = User.objects.get(username= user.username)
profile.save()
return redirect(self.success_url)
from .views import *
urlpatterns = [
url(r'^addemp/$', addEmployee.as_view(), name='addemp'),
]

不会自动创建mediaPlaybackRequiresUserAction对象。要同时创建employee对象和user对象，可以使用employee实例
user
