从Django 1.5开始，你可以很容易地扩展用户模型，在数据库中只保留一个表。

from django.contrib.auth.models import AbstractUser
from django.db import models
from django.utils.translation import ugettext_lazy as _

class UserProfile(AbstractUser):
    age = models.PositiveIntegerField(_("age"))

您还必须在设置文件中将其配置为当前用户类

# supposing you put it in apps/profiles/models.py
AUTH_USER_MODEL = "profiles.UserProfile"

如果你想添加很多用户的首选项，OneToOneField选项可能是一个更好的选择。

给开发第三方库的人一个提示:如果您需要访问用户类，请记住人们可以更改它。使用官方帮助获取正确的类

from django.contrib.auth import get_user_model

User = get_user_model()

现在已经太迟了，但我的答案是给那些用最新版本的Django寻找解决方案的人的。

models.py:

from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver


class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    extra_Field_1 = models.CharField(max_length=25, blank=True)
    extra_Field_2 = models.CharField(max_length=25, blank=True)


@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)

@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
    instance.profile.save()

你可以在这样的模板中使用它:

<h2>{{ user.get_full_name }}</h2>
<ul>
  <li>Username: {{ user.username }}</li>
  <li>Location: {{ user.profile.extra_Field_1 }}</li>
  <li>Birth Date: {{ user.profile.extra_Field_2 }}</li>
</ul>

在views.py中是这样的:

def update_profile(request, user_id):
    user = User.objects.get(pk=user_id)
    user.profile.extra_Field_1 = 'Lorem ipsum dolor sit amet, consectetur adipisicing elit...'
    user.save()

试试这个:

创建一个名为Profile的模型，并使用OneToOneField引用用户，并提供一个related_name选项。

models.py

from django.db import models
from django.contrib.auth.models import *
from django.dispatch import receiver
from django.db.models.signals import post_save

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='user_profile')

    def __str__(self):
        return self.user.username

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    try:
        if created:
            Profile.objects.create(user=instance).save()
    except Exception as err:
        print('Error creating user profile!')

现在要使用User对象直接访问配置文件，可以使用related_name。

views.py

from django.http import HttpResponse

def home(request):
    profile = f'profile of {request.user.user_profile}'
    return HttpResponse(profile)

这是Django 1.5中的新功能，现在你可以创建自己的自定义用户模型(在上述情况下，这似乎是一件好事)。参考“在Django中自定义身份验证”

这可能是1.5版本中最酷的新功能。

简单而有效的方法是 models.py

from django.contrib.auth.models import User
class CustomUser(User):
     profile_pic = models.ImageField(upload_to='...')
     other_field = models.CharField()

你可以通过每次使用Django post save信号创建用户时创建一个新条目来扩展用户配置文件

models.py

from django.db.models.signals import *
from __future__ import unicode_literals

class UserProfile(models.Model):

    user_name = models.OneToOneField(User, related_name='profile')
    city = models.CharField(max_length=100, null=True)

    def __unicode__(self):  # __str__
        return unicode(self.user_name)

def create_user_profile(sender, instance, created, **kwargs):
    if created:
        userProfile.objects.create(user_name=instance)

post_save.connect(create_user_profile, sender=User)

这将在创建新用户时自动创建一个雇员实例。

如果你想扩展用户模型，并在创建用户时添加更多信息，你可以使用django-betterforms (http://django-betterforms.readthedocs.io/en/latest/multiform.html)。这将创建一个包含UserProfile模型中定义的所有字段的用户添加表单。

models.py

from django.db.models.signals import *
from __future__ import unicode_literals

class UserProfile(models.Model):

    user_name = models.OneToOneField(User)
    city = models.CharField(max_length=100)

    def __unicode__(self):  # __str__
        return unicode(self.user_name)

forms.py

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 ProfileForm(ModelForm):

    class Meta:
        model = Employee
        exclude = ('user_name',)


class addUserMultiForm(MultiModelForm):
    form_classes = {
        'user':UserCreationForm,
        'profile':ProfileForm,
    }

views.py

from django.shortcuts import redirect
from .models import *
from .forms import *
from django.views.generic import CreateView

class AddUser(CreateView):
    form_class = AddUserMultiForm
    template_name = "add-user.html"
    success_url = '/your-url-after-user-created'

    def form_valid(self, form):
        user = form['user'].save()
        profile = form['profile'].save(commit=False)
        profile.user_name = User.objects.get(username= user.username)
        profile.save()
        return redirect(self.success_url)

addUser.html

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
        <form action="." method="post">
            {% csrf_token %}
            {{ form }}     
            <button type="submit">Add</button>
        </form>
     </body>
</html>

urls . py

from django.conf.urls import url, include
from appName.views import *
urlpatterns = [
    url(r'^add-user/$', AddUser.as_view(), name='add-user'),
]
