Utilisez le `email` comme nom d'utilisateur et débarrassez-vous du champ` username`

Si vous voulez vous débarrasser du champ username et utiliser le email comme identifiant d'utilisateur unique, vous devrez créer un modèle d' User personnalisé étendant AbstractBaseUser au lieu de AbstractUser . En effet, le username et le email sont définis dans AbstractUser et vous ne pouvez pas les remplacer. Cela signifie que vous devrez également redéfinir tous les champs que vous souhaitez définir dans AbstractUser .

Notre classe UserProfile

Créez une classe de modèle UserProfile avec la relation de OneToOne avec le modèle d' User par défaut:

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 Signals at work

En utilisant les signaux Django, créez un nouveau UserProfile User immédiatement après la UserProfile un objet User . Cette fonction peut être UserProfile sous la classe de modèle UserProfile dans le même fichier ou la placer où vous le souhaitez. Je m'en fous, autant que vous le référencez correctement.

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 à la rescousse

Maintenant, pour vos views.py , vous pourriez avoir quelque chose comme ceci:

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

@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

Notre modèle

Ensuite, account_update.html tout dans votre template account_update.html comme account_update.html :

{% 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>

Spécification d'un modèle d'utilisateur personnalisé

Le modèle d' User intégré de Django n'est pas toujours adapté à certains types de projets. Sur certains sites, il peut être plus judicieux d'utiliser une adresse e-mail plutôt qu'un nom d'utilisateur, par exemple.

Vous pouvez remplacer le modèle d' User par défaut en ajoutant votre modèle d' User personnalisé au paramètre AUTH_USER_MODEL , dans le fichier de paramètres de vos projets:

AUTH_USER_MODEL = 'myapp.MyUser'

Notez qu'il est fortement recommandé de créer AUTH_USER_MODEL avant de créer des migrations ou d'exécuter manage.py migrate pour la première fois. En raison des limitations de la fonction de dépendance synamique de Django.

Par exemple, sur votre blog, vous voudrez peut-être que d'autres auteurs puissent se connecter avec une adresse e-mail au lieu du nom d'utilisateur habituel. Nous créons donc un modèle d' User personnalisé avec une adresse e-mail comme USERNAME_FIELD :

from django.contrib.auth.models import AbstractBaseUser

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

En héritant de AbstractBaseUser nous pouvons construire un modèle d' User conforme. AbstractBaseUser fournit l'implémentation principale d'un modèle d' User .

Pour que la commande Django manage.py createsuperuser sache quels autres champs sont nécessaires, nous pouvons spécifier un REQUIRED_FIELDS . Cette valeur n'a aucun effet dans d'autres parties de Django!

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

Pour être compatible avec une autre partie de Django, nous devons toujours spécifier la valeur is_active , les fonctions get_full_name() et 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

Vous devez également créer un UserManager personnalisé pour votre modèle User , ce qui permet à Django d'utiliser les fonctions create_user() et 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

Référencement du modèle d'utilisateur

Votre code ne fonctionnera pas dans les projets où vous référencez le modèle User ( et où le paramètre AUTH_USER_MODEL a été modifié ) directement.

Par exemple: si vous souhaitez créer Post modèle Post pour un blog avec un modèle d' User personnalisé, vous devez spécifier le modèle d' User personnalisé comme suit:

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)
