在Django中接受电子邮件地址作为用户名

如果有人想这么做,我建议你看看 django-email-as-username 这是一个非常全面的解决方案,包括修补管理员和 createsuperuser 管理命令,以及其他零碎信息。

编辑 :从Django 1.5开始,您应该考虑使用 custom user model 而不是 django电子邮件用户名 .

这是我们要做的。这不是一个“完整”的解决方案,但它能满足你的大部分需求。

from django import forms
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import User

class UserForm(forms.ModelForm):
    class Meta:
        model = User
        exclude = ('email',)
    username = forms.EmailField(max_length=64,
                                help_text="The person's email address.")
    def clean_email(self):
        email = self.cleaned_data['username']
        return email

class UserAdmin(UserAdmin):
    form = UserForm
    list_display = ('email', 'first_name', 'last_name', 'is_staff')
    list_filter = ('is_staff',)
    search_fields = ('email',)

admin.site.unregister(User)
admin.site.register(User, UserAdmin)

有一种方法可以同时接受用户名和电子邮件:

from django.contrib.auth.forms import AuthenticationForm
from django.contrib.auth.models import User
from django.core.exceptions import ObjectDoesNotExist
from django.forms import ValidationError

class EmailAuthenticationForm(AuthenticationForm):
    def clean_username(self):
        username = self.data['username']
        if '@' in username:
            try:
                username = User.objects.get(email=username).username
            except ObjectDoesNotExist:
                raise ValidationError(
                    self.error_messages['invalid_login'],
                    code='invalid_login',
                    params={'username':self.username_field.verbose_name},
                )
        return username

不知道是否有设置来设置默认身份验证表单,但也可以重写url.py中的url

url(r'^accounts/login/$', 'django.contrib.auth.views.login', { 'authentication_form': EmailAuthenticationForm }, name='login'),

当提交无效电子邮件时,提升ValidationError将防止500个错误。使用super对“invalid_login”的定义会使错误消息保持不明确(与特定的“未找到该电子邮件的用户”相比),这将是防止泄露电子邮件地址是否已注册到您服务的帐户所必需的。如果该信息在您的体系结构中不安全,那么可能会有一个更具信息性的错误消息。

Django现在提供了一个扩展身份验证系统的完整示例,其中包含管理和表单: https://docs.djangoproject.com/en/stable/topics/auth/customizing/#a-full-example

你基本上可以复制/粘贴它并适应(我不需要 date_of_birth 就我而言)。

它实际上是从Django 1.5开始提供的,现在仍然可以使用(django1.7)。

如果要扩展用户模型,无论如何都必须实现自定义用户模型。

这里是Django 1.8的一个例子。Django 1.7需要更多的工作,主要是更改默认表单(只需看看 UserChangeForm &安培; UserCreationForm 在里面 django.contrib.auth.forms -这就是你在1.7中需要的。

用户管理器.py:

from django.contrib.auth.models import BaseUserManager
from django.utils import timezone

class SiteUserManager(BaseUserManager):
    def create_user(self, email, password=None, **extra_fields):
        today = timezone.now()

        if not email:
            raise ValueError('The given email address must be set')

        email = SiteUserManager.normalize_email(email)
        user  = self.model(email=email,
                          is_staff=False, is_active=True, **extra_fields)

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

    def create_superuser(self, email, password, **extra_fields):
        u = self.create_user(email, password, **extra_fields)
        u.is_staff = True
        u.is_active = True
        u.is_superuser = True
        u.save(using=self._db)
        return u

型号.py:

from mainsite.user_manager import SiteUserManager

from django.contrib.auth.models import AbstractBaseUser
from django.contrib.auth.models import PermissionsMixin

class SiteUser(AbstractBaseUser, PermissionsMixin):
    email    = models.EmailField(unique=True, blank=False)

    is_active   = models.BooleanField(default=True)
    is_admin    = models.BooleanField(default=False)
    is_staff    = models.BooleanField(default=False)

    USERNAME_FIELD = 'email'

    objects = SiteUserManager()

    def get_full_name(self):
        return self.email

    def get_short_name(self):
        return self.email

forms.py格式:

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.forms import UserChangeForm, UserCreationForm
from mainsite.models import SiteUser

class MyUserCreationForm(UserCreationForm):
    class Meta(UserCreationForm.Meta):
        model = SiteUser
        fields = ("email",)


class MyUserChangeForm(UserChangeForm):
    class Meta(UserChangeForm.Meta):
        model = SiteUser


class MyUserAdmin(UserAdmin):
    form = MyUserChangeForm
    add_form = MyUserCreationForm

    fieldsets = (
        (None,              {'fields': ('email', 'password',)}),
        ('Permissions',     {'fields': ('is_active', 'is_staff', 'is_superuser',)}),  
        ('Groups',          {'fields': ('groups', 'user_permissions',)}),
    )

    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('email', 'password1', 'password2')}
        ),
    )

    list_display = ('email', )       
    list_filter = ('is_active', )    
    search_fields = ('email',)       
    ordering = ('email',)


admin.site.register(SiteUser, MyUserAdmin)

设置.py:

AUTH_USER_MODEL = 'mainsite.SiteUser'

其他替代方案对我来说太复杂了,所以我编写了一个代码片段,允许使用用户名、电子邮件或两者进行身份验证,还允许启用或禁用区分大小写。我把它作为 django-dual-authentication .

                # difference between an existing and a non-existing user.
                UserModel().set_password(password)
                return None

最新版本的django注册允许一些很好的定制,可以在这里完成工作文档 https://bitbucket.org/ubernostrum/django-registration/src/fad7080fe769/docs/backend-api.rst

     if user_form.is_valid():
        # Save the user's form data to a user object without committing.
        user = user_form.save(commit=False)
        user.set_password(user.password)
        #Set username of user as the email
        user.username = user.email
        #commit
        user.save()

工作完美。。。对于django 1.11.4

最简单的方法是根据登录视图中的电子邮件查找用户名。这样你就可以不去管其他事情了:

from django.contrib.auth import authenticate, login as auth_login

def _is_valid_email(email):
    from django.core.validators import validate_email
    from django.core.exceptions import ValidationError
    try:
        validate_email(email)
        return True
    except ValidationError:
        return False

def login(request):

    next = request.GET.get('next', '/')

    if request.method == 'POST':
        username = request.POST['username'].lower()  # case insensitivity
        password = request.POST['password']

    if _is_valid_email(username):
        try:
            username = User.objects.filter(email=username).values_list('username', flat=True)
        except User.DoesNotExist:
            username = None
    kwargs = {'username': username, 'password': password}
    user = authenticate(**kwargs)

        if user is not None:
            if user.is_active:
                auth_login(request, user)
                return redirect(next or '/')
            else:
                messages.info(request, "<stvrong>Error</strong> User account has not been activated..")
        else:
            messages.info(request, "<strong>Error</strong> Username or password was incorrect.")

    return render_to_response('accounts/login.html', {}, context_instance=RequestContext(request))

在模板中相应地设置下一个变量,即。

<form method="post" class="form-login" action="{% url 'login' %}?next={{ request.GET.next }}" accept-charset="UTF-8">

并输入正确的用户名/密码,即用户名、密码。

更新 :

或者,如果“是有效的”电子邮件(电子邮件):可以用用户名中的if“@”替换呼叫。这样您就可以删除有效的电子邮件功能。这真的取决于你如何定义你的用户名。如果您允许用户名中有“@”字符,它将不起作用。

我认为最快的方法是创建一个继承自 UserCreateForm ,然后重写 username 字段 forms.EmailField . 然后,对于每个新的注册用户,他们需要用他们的电子邮件地址登录。

例如:

网址.py

...
urlpatterns += url(r'^signon/$', SignonView.as_view(), name="signon")

视图.py

from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
from django import forms

class UserSignonForm(UserCreationForm):
    username = forms.EmailField()


class SignonView(CreateView):
    template_name = "registration/signon.html"
    model = User
    form_class = UserSignonForm

signon.html网站

...
<form action="#" method="post">
    ...
    <input type="email" name="username" />
    ...
</form>
...

不确定人们是否正在尝试完成这一点,但我找到了一个很好的(干净的)方法,只要求电子邮件,然后在保存之前将用户名设置为视图中的电子邮件。

我的用户表单只需要电子邮件和密码:

class UserForm(forms.ModelForm):
    password = forms.CharField(widget=forms.PasswordInput())

    class Meta:
        model = User
        fields = ('email', 'password')

然后在我看来,我添加了以下逻辑:

if user_form.is_valid():
            # Save the user's form data to a user object without committing.
            user = user_form.save(commit=False)

            user.set_password(user.password)
            #Set username of user as the email
            user.username = user.email
            #commit
            user.save()
