Gebruik de `email` als gebruikersnaam en verwijder het veld` gebruikersnaam`

Als u wilt om zich te ontdoen van het krijgen username veld en het gebruik email als unieke gebruikers-ID, moet u een aangepaste maken User model uitbreiding van AbstractBaseUser plaats van AbstractUser . Inderdaad, username en email zijn gedefinieerd in AbstractUser en u kunt ze niet overschrijven. Dit betekent dat u ook alle velden die u wilt definiëren in AbstractUser opnieuw moet definiëren.

Onze UserProfile klasse

Maak een UserProfile model klas met de relatie van OneToOne naar de standaard User model:

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-signalen op het werk

Maak met behulp van Django-signalen een nieuw UserProfile onmiddellijk UserProfile een User object is gemaakt. Deze functie kan worden weggestopt onder de UserProfile in hetzelfde bestand, of worden geplaatst waar u maar wilt. Het kan me niet schelen, net zo goed als je er goed naar verwijst.

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 te hulp

Voor uw views.py heeft u misschien zoiets als dit:

from django.shortcuts import render, HttpResponseRedirect
from django.contrib.auth.decorators import login_required

from .models import UserProfile

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/')

Een aangepast gebruikersmodel specificeren

Het ingebouwde User Django is niet altijd geschikt voor sommige soorten projecten. Op sommige sites kan het logischer zijn om bijvoorbeeld een e-mailadres te gebruiken in plaats van een gebruikersnaam.

U kunt het standaard User overschrijven door uw aangepaste User toe te voegen aan de instelling AUTH_USER_MODEL in uw bestand met projectinstellingen:

AUTH_USER_MODEL = 'myapp.MyUser'

Houd er rekening mee dat het zeer raadzaam is om AUTH_USER_MODEL te maken voordat u migraties maakt of voor het eerst migraties met manage.py migrate . Vanwege beperkingen van de synamic afhankelijkheidsfunctie van Django.

Op uw blog wilt u bijvoorbeeld dat andere auteurs zich kunnen aanmelden met een e-mailadres in plaats van de gewone gebruikersnaam. Daarom maken we een aangepast User met een e-mailadres als USERNAME_FIELD :

from django.contrib.auth.models import AbstractBaseUser

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

Door de AbstractBaseUser erven, kunnen we een compatibel User . AbstractBaseUser biedt de kernimplementatie van een User .

Om de opdracht Django manage.py createsuperuser te laten weten welke andere velden vereist zijn, kunnen we een REQUIRED_FIELDS specificeren. Deze waarde heeft geen effect in andere delen van Django!

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

Om te voldoen aan andere delen van Django moeten we nog steeds de waarde is_active opgeven, de functies get_full_name() en 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

U moet ook een aangepaste UserManager voor uw User maken, waarmee Django de create_user() en create_superuser() kan gebruiken:

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

Verwijzen naar het gebruikersmodel

Uw code werkt niet in projecten waar u rechtstreeks naar het User verwijst ( en waar de instelling AUTH_USER_MODEL is gewijzigd ).

Bijvoorbeeld: als je wilt maken Post model voor een blog met een aangepaste User model, moet u de aangepaste opgeven User model als volgt uit:

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)
