Используйте `email` как имя пользователя и избавитесь от поля` username '

Если вы хотите избавиться от поля username и использовать email качестве уникального идентификатора пользователя, вам нужно будет создать User модель, расширяющую AbstractBaseUser вместо AbstractUser . Действительно, username и email определены в AbstractUser и вы не можете их переопределить. Это означает, что вам также придется переопределять все поля, которые вы хотите определить в AbstractUser .

Расширить модель пользователя Django

Наш класс UserProfile

Создайте UserProfile модели UserProfile с отношением OneToOne к модели User по умолчанию:

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

class UserProfile(models.Model):
    user = models.OneToOneField(User, related_name='user')
    photo = FileField(verbose_name=_("Profile Picture"),
                      upload_to=upload_to("main.UserProfile.photo", "profiles"),
                      format="Image", max_length=255, null=True, blank=True)
    website = models.URLField(default='', blank=True)
    bio = models.TextField(default='', blank=True)
    phone = models.CharField(max_length=20, blank=True, default='')
    city = models.CharField(max_length=100, default='', blank=True)
    country = models.CharField(max_length=100, default='', blank=True)
    organization = models.CharField(max_length=100, default='', blank=True)

Django Сигналы на работе

Используя Django Signals, создайте новый UserProfile сразу же, UserProfile объект User . Эта функция может быть UserProfile под UserProfile модели UserProfile в том же файле или размещать ее там, где вам нравится. Меня не волнует, так же, как вы его правильно ссылаетесь.

def create_profile(sender, **kwargs):
    user = kwargs["instance"]
    if kwargs["created"]:
        user_profile = UserProfile(user=user)
        user_profile.save()
post_save.connect(create_profile, sender=User)

inlineformset_factory для спасения

Теперь для вашего views.py вы можете иметь что-то вроде этого:

from django.shortcuts import render, HttpResponseRedirect
from django.contrib.auth.decorators import login_required
from django.contrib.auth.models import User
from .models import UserProfile
from .forms import UserForm
from django.forms.models import inlineformset_factory
from django.core.exceptions import PermissionDenied
@login_required() # only logged in users should access this
def edit_user(request, pk):
    # querying the User object with pk from url
    user = User.objects.get(pk=pk)

    # prepopulate UserProfileForm with retrieved user values from above.
    user_form = UserForm(instance=user)

    # The sorcery begins from here, see explanation https://blog.khophi.co/extending-django-user-model-userprofile-like-a-pro/
    ProfileInlineFormset = inlineformset_factory(User, UserProfile, fields=('website', 'bio', 'phone', 'city', 'country', 'organization'))
    formset = ProfileInlineFormset(instance=user)

    if request.user.is_authenticated() and request.user.id == user.id:
        if request.method == "POST":
            user_form = UserForm(request.POST, request.FILES, instance=user)
            formset = ProfileInlineFormset(request.POST, request.FILES, instance=user)

            if user_form.is_valid():
                created_user = user_form.save(commit=False)
                formset = ProfileInlineFormset(request.POST, request.FILES, instance=created_user)

                if formset.is_valid():
                    created_user.save()
                    formset.save()
                    return HttpResponseRedirect('/accounts/profile/')

        return render(request, "account/account_update.html", {
            "noodle": pk,
            "noodle_form": user_form,
            "formset": formset,
        })
    else:
        raise PermissionDenied

Наш шаблон

Затем переместите все на свой шаблон account_update.html так:

{% load material_form %}
<!-- Material form is just a materialize thing for django forms -->
<div class="col s12 m8 offset-m2">
      <div class="card">
        <div class="card-content">
        <h2 class="flow-text">Update your information</h2>
          <form action="." method="POST" class="padding">
            {% csrf_token %} {{ noodle_form.as_p }}
            <div class="divider"></div>
            {{ formset.management_form }}
                {{ formset.as_p }}
            <button type="submit" class="btn-floating btn-large waves-light waves-effect"><i class="large material-icons">done</i></button>
            <a href="#" onclick="window.history.back(); return false;" title="Cancel" class="btn-floating waves-effect waves-light red"><i class="material-icons">history</i></a>
 
        </form>
        </div>
    </div>
</div>

Выделенный фрагмент из расширенного пользовательского файла Django, такого как Pro

Спецификация пользовательской модели пользователя

Встроенная User модель Django не всегда подходит для некоторых проектов. На некоторых сайтах может быть больше смысла использовать адрес электронной почты вместо имени пользователя.

Вы можете переопределить модель User по умолчанию, добавив вашу User модель User в параметр AUTH_USER_MODEL в файле настроек проектов:

AUTH_USER_MODEL = 'myapp.MyUser'

Обратите внимание, что настоятельно AUTH_USER_MODEL создать AUTH_USER_MODEL прежде чем создавать какие-либо миграции или запускать manage.py migrate в первый раз. Из-за ограничений функции динамической зависимости Django.

Например, в вашем блоге вы можете захотеть, чтобы другие авторы имели возможность входа в систему с адресом электронной почты вместо обычного имени пользователя, поэтому мы создаем User модель User с адресом электронной почты как USERNAME_FIELD :

from django.contrib.auth.models import AbstractBaseUser

class CustomUser(AbstractBaseUser):
     email = models.EmailField(unique=True)
     
     USERNAME_FIELD = 'email'

Наследуя AbstractBaseUser мы можем построить совместимую модель User . AbstractBaseUser обеспечивает основную реализацию модели User .

Чтобы команда Django manage.py createsuperuser знала, какие другие поля необходимы, мы можем указать REQUIRED_FIELDS . Это значение не влияет на другие части Django!

class CustomUser(AbstractBaseUser):
    ...
    first_name = models.CharField(max_length=254)
    last_name = models.CharField(max_length=254)
    ...
    REQUIRED_FIELDS = ['first_name', 'last_name']

Чтобы быть совместимым с другой частью Django, нам все равно нужно указать значение is_active , функции get_full_name() и get_short_name() :

class CustomUser(AbstractBaseUser):
    ...
    is_active = models.BooleanField(default=False)
    ...
    def get_full_name(self):
        full_name = "{0} {1}".format(self.first_name, self.last_name)
        return full_name.strip()

    def get_short_name(self):
        return self.first_name

Вы также должны создать пользовательский UserManager для своей модели User , который позволяет Django использовать функции create_user() и create_superuser() :

from django.contrib.auth.models import BaseUserManager

class CustomUserManager(BaseUserManager):
    def create_user(self, email, first_name, last_name, password=None):
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
        )

        user.set_password(password)
        user.first_name = first_name
        user.last_name = last_name
        user.save(using=self._db)
        return user

    def create_superuser(self, email, first_name, last_name, password):
        user = self.create_user(
            email=email,
            first_name=first_name,
            last_name=last_name,
            password=password,
        )

        user.is_admin = True
        user.is_active = True
        user.save(using=self.db)
        return user

Ссылка на модель пользователя

Ваш код не будет работать в проектах, где вы ссылаетесь на модель User ( и где значение AUTH_USER_MODEL было изменено ) напрямую.

Например: если вы хотите создать Post модель для блога с User моделью User , вы должны указать User модель User следующим образом:

from django.conf import settings
from django.db import models

class Post(models.Model):
    author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
