在Django 1.11中使用email登錄，我使用cookiecutter-django with allauth

Question

我開始使用 cookiecutter-django，因為它似乎比 django-admin 更先進來啟動我的項目。 所以我創建了一個電子商務網站，它只需要電子郵件即可登錄，而不需要用戶名。

因此，我嘗試按照文檔並像這樣更改我的 settings.py：

ACCOUNT_USER_MODEL_USERNAME_FIELD = None
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_USERNAME_REQUIRED = False
ACCOUNT_AUTHENTICATION_METHOD = 'email'
ACCOUNT_EMAIL_VERIFICATION = 'mandatory'

AUTH_USER_MODEL = 'accounts.User'
LOGIN_REDIRECT_URL = 'users:redirect'
LOGIN_URL = 'account_login'

這是我的帳戶。用戶模型：

from django.db import models
from django.contrib.auth.models import (
    AbstractBaseUser, BaseUserManager
)

class UserManager(BaseUserManager):
    def create_user(self, email, full_name, password=None, is_active=True, is_staff=False, is_admin=False):
        if not email:
            raise ValueError("Users must have an email address")
        if not password:
            raise ValueError("Users must have a password")
        if not full_name:
            raise ValueError("Users must have a fullname")

        user_obj = self.model(
            email = self.normalize_email(email),
            full_name = full_name
        )
        user_obj.set_password(password)
        user_obj.staff = is_staff
        user_obj.admin = is_admin
        user_obj.active = is_active
        user_obj.save(using=self._db)
        return user_obj

    def create_staffuser(self, email, full_name, password=None):
        user = self.create_user(
            email,
            full_name,
            password=password,
            is_staff=True
        )
        return user

    def create_superuser(self, email, full_name, password=None):
        user = self.create_user(
            email,
            full_name,
            password=password,
            is_staff=True,
            is_admin=True
        )
        return user


class User(AbstractBaseUser):
    email       = models.EmailField(max_length=255, unique=True)
    full_name   = models.CharField(max_length=255, blank=True, null=True)
    active      = models.BooleanField(default=True)
    staff       = models.BooleanField(default=False)
    admin       = models.BooleanField(default=False)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELD = ['full_name']

    objects = UserManager()

    def __str__(self):
        return self.email

    def get_full_name(self):
        return self.full_name

    def get_short_name(self):
        return self.email

    def has_perm(self, perm, obj=None):
        return True

    def has_module_perms(self, app_label):
        return True

    @property
    def is_staff(self):
        return self.staff

    @property
    def is_admin(self):
        return self.admin

    @property
    def is_active(self):
        return self.active

有默認users目錄，它有自己的 models.py、views.py 和 urls.py，但我不知道修改它。

網址.py：

from django.conf.urls import url

from . import views

urlpatterns = [
    url(
        regex=r'^$',
        view=views.UserListView.as_view(),
        name='list'
    ),
    url(
        regex=r'^~redirect/$',
        view=views.UserRedirectView.as_view(),
        name='redirect'
    ),
    url(
        regex=r'^(?P<username>[\w.@+-]+)/$',
        view=views.UserDetailView.as_view(),
        name='detail'
    ),
    url(
        regex=r'^~update/$',
        view=views.UserUpdateView.as_view(),
        name='update'
    ),
]

模型.py：

from django.contrib.auth.models import AbstractUser
from django.core.urlresolvers import reverse
from django.db import models
from django.utils.encoding import python_2_unicode_compatible
from django.utils.translation import ugettext_lazy as _


@python_2_unicode_compatible
class User(AbstractUser):

    # First Name and Last Name do not cover name patterns
    # around the globe.
    name = models.CharField(_('Name of User'), blank=True, max_length=255)

    def __str__(self):
        return self.username

    def get_absolute_url(self):
        return reverse('users:detail', kwargs={'username': self.username})

視圖.py：

from django.core.urlresolvers import reverse
from django.views.generic import DetailView, ListView, RedirectView, UpdateView

from django.contrib.auth.mixins import LoginRequiredMixin

from .models import User
from enrolments.models import Enrolment


class UserDetailView(LoginRequiredMixin, DetailView):
    model = User
    # These next two lines tell the view to index lookups by username
    slug_field = 'username'
    slug_url_kwarg = 'username'


class UserRedirectView(LoginRequiredMixin, RedirectView):
    permanent = False

    def get_redirect_url(self):
        return reverse('users:detail',
                       kwargs={'username': self.request.user.username})


class UserUpdateView(LoginRequiredMixin, UpdateView):

    fields = ['name', ]

    # we already imported User in the view code above, remember?
    model = User

    # send the user back to their own page after a successful update
    def get_success_url(self):
        return reverse('users:detail',
                       kwargs={'username': self.request.user.username})

    def get_object(self):
        # Only get the User record for the user making the request
        return User.objects.get(username=self.request.user.username)


class UserListView(LoginRequiredMixin, ListView):
    model = User
    # These next two lines tell the view to index lookups by username
    slug_field = 'username'
    slug_url_kwarg = 'username'

這是我登錄時的錯誤，盡管它讓我在進入主頁時登錄。 但是當我點擊“登錄”按鈕時，它會提示我這個錯誤。 請指導我完成它。

提前謝謝你。

Answer 1

截至目前（2020 年 6 月），有一種更簡單的方法可以使用 Django Cookie 切割器執行此操作。

首先在 Django 設置config/settings/base.py我們需要調整 AllAuth 設置，以便首先使用電子郵件作為主要標識符而不是用戶名，其次使用戶名字段隱藏在注冊頁面中

ACCOUNT_AUTHENTICATION_METHOD = "email"
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_USERNAME_REQUIRED = False
ACCOUNT_EMAIL_VERIFICATION = "mandatory"

可以在此處找到 Django AllAuth 文檔

然后在 User 模型中，我們添加一個信號，該信號將在用戶實例更新時觸發，並將電子郵件地址復制到 username 字段。 這樣他們就保持同步。 如果有沖突的電子郵件地址（它們不應該是），while 循環只處理這種情況：

@receiver(pre_save, sender=User)
def update_username_from_email(sender, instance, **kwargs):
    user_email = instance.email
    username = user_email[:130]
    n = 1
    while User.objects.exclude(pk=instance.pk).filter(username=username).exists():
        n += 1
        username = user_email[: (129 - len(str(n)))] + "-" + str(n)
    instance.username = username

這個用戶模型更新是由@ferrangb 在這里提出的

最后，我設法找到了方法。 這是我的新models.py：

from django.db import models
from django.contrib.auth.models import (
    AbstractBaseUser, BaseUserManager
)

class UserManager(BaseUserManager):

    def create_user(self, email, username, full_name, password=None, is_active=True, is_staff=False, is_admin=False):
        if not email:
            raise ValueError("Users must have an email address")
        if not password:
            raise ValueError("Users must have a password")
        if not full_name:
            raise ValueError("Users must have a fullname")

        user_obj = self.model(
            email = self.normalize_email(email),
            full_name = full_name,
            username = new_username
        )
        user_obj.set_password(password)
        user_obj.staff = is_staff
        user_obj.admin = is_admin
        user_obj.active = is_active
        user_obj.save(using=self._db)
        return user_obj

    def create_staffuser(self, username, email, full_name, password=None):
        user = self.create_user(
            email,
            full_name,
            username=username,
            password=password,
            is_staff=True
        )
        return user

    def create_superuser(self, username, email, full_name, password=None):
        user = self.create_user(
            email,
            full_name,
            username=username,
            password=password,
            is_staff=True,
            is_admin=True
        )
        return user




class User(AbstractBaseUser):
    email       = models.EmailField(max_length=255, unique=True)
    full_name   = models.CharField(max_length=255, blank=True, null=True)
    username    = models.CharField(max_length=255, blank=True, null=True)
    active      = models.BooleanField(default=True)
    staff       = models.BooleanField(default=False)
    admin       = models.BooleanField(default=False)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELD = ['full_name']

    objects = UserManager()

    def __str__(self):
        return self.email

    def get_full_name(self):
        return self.full_name

    def get_short_name(self):
        return self.email

    def get_username(self):
        return self.username

    def has_perm(self, perm, obj=None):
        return True

    def has_module_perms(self, app_label):
        return True

    @property
    def is_staff(self):
        return self.staff

    @property
    def is_admin(self):
        return self.admin

    @property
    def is_active(self):
        return self.active

這是我在“用戶”目錄中的 views.py 文件：

from django.core.urlresolvers import reverse
from django.views.generic import DetailView, ListView, RedirectView, UpdateView

from django.contrib.auth.mixins import LoginRequiredMixin

from accounts.models import User
from enrolments.models import Enrolment


class UserDetailView(LoginRequiredMixin, DetailView):
    model = User
    # These next two lines tell the view to index lookups by username
    slug_field = 'username'
    slug_url_kwarg = 'username'


class UserRedirectView(LoginRequiredMixin, RedirectView):
    permanent = False

    def get_redirect_url(self):
        return reverse('users:detail',
                       kwargs={'username': self.request.user.username})


class UserUpdateView(LoginRequiredMixin, UpdateView):

    fields = ['full_name', ]

    # we already imported User in the view code above, remember?
    model = User

    # send the user back to their own page after a successful update
    def get_success_url(self):
        return reverse('users:detail',
                       kwargs={'username': self.request.user.username})

    def get_object(self):
        # Only get the User record for the user making the request
        return User.objects.get(username=self.request.user.username)


class UserListView(LoginRequiredMixin, ListView):
    model = User
    # These next two lines tell the view to index lookups by username
    slug_field = 'username'
    slug_url_kwarg = 'username'

和我的 settings.py 文件：

# ACCOUNT_USER_MODEL_USERNAME_FIELD = None
ACCOUNT_EMAIL_REQUIRED = True
# ACCOUNT_USERNAME_REQUIRED = False
ACCOUNT_AUTHENTICATION_METHOD = 'email'
ACCOUNT_EMAIL_VERIFICATION = 'mandatory'

AUTH_USER_MODEL = 'accounts.User'
LOGIN_REDIRECT_URL = 'users:redirect'
LOGIN_URL = 'account_login'

雖然，我只需要在注冊時有用戶名，但在那之后，它就可以工作了。 我不需要更改任何其他文件。 我希望這會有所幫助。 謝謝。
