在Django 3.0+版本中非常简单(如果你不是在项目中):

在models.py

from django.db import models
from django.contrib.auth.models import AbstractUser

class CustomUser(AbstractUser):
    extra_field=models.CharField(max_length=40)

在settings.py

首先，注册你的新应用，然后在AUTH_PASSWORD_VALIDATORS下面 添加

AUTH_USER_MODEL ='users.CustomUser'

最后，在管理中注册你的模型，运行makemigrations和migrate，它将成功完成。

官方文档:https://docs.djangoproject.com/en/3.2/topics/auth/customizing/#substituting-a-custom-user-model

像Pro一样扩展Django用户模型(UserProfile)

我发现这个非常有用:link

摘录:

from django.contrib.auth.models import User

class Employee(models.Model):
    user = models.OneToOneField(User)
    department = models.CharField(max_length=100)

>>> u = User.objects.get(username='fsmith')
>>> freds_department = u.employee.department

在这里，我试图解释如何用额外的字段来扩展Django的Default用户模型 很简单，就这么做。

Django允许使用AbstractUser扩展默认的用户模型

注意:-首先创建一个额外的字段模型，你想添加到用户模型，然后运行命令python manage.py makemigrations和python manage.py migrate

首先运行——> python manage.py makemigrationthen

第二步运行python manage.py migrate

步骤:-创建一个带有额外字段的模型，你想在Django默认用户模型中添加这些字段(在我的例子中，我创建了CustomUser

model.py

from django.db import models
from django.contrib.auth.models import AbstractUser
# Create your models here.


class CustomUser(AbstractUser):
    mobile_no = models.IntegerField(blank=True,null=True)
    date_of_birth = models.DateField(blank=True,null=True)

在settings.py中添加你创建的模型名称，在我的例子中CustomUser是用户模型。在settings .py中注册，使其成为默认用户模型，

#settings.py

AUTH_USER_MODEL = 'myapp.CustomUser'

最后在admin.py中注册CustomUser模型 # admin.py

@admin.register(CustomUser)
class CustomUserAdmin(admin.ModelAdmin):
    list_display = ("username","first_name","last_name","email","date_of_birth", "mobile_no")

然后执行命令python manage.py makemigrations

然后python manage.py migrate

然后python manage.py createsuperuser

现在你可以看到你的模型默认用户模型扩展了(mobile_no,date_of_birth)

关于存储用户的附加信息，有一个官方建议。 Django手册也在Profiles部分讨论了这个问题。

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()

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'),
]
