Python 仅使用电子邮件和密码创建Django用户-UserCreationForm
我需要在我的应用程序中仅使用Python 仅使用电子邮件和密码创建Django用户-UserCreationForm,python,django,django-users,Python,Django,Django Users,我需要在我的应用程序中仅使用电子邮件和密码字段创建一个用户帐户。因此,my models.py中的自定义用户模型为: 我自定义UserManager以创建用户 from django.contrib.auth.models import BaseUserManager class UserManager(BaseUserManager): def _create_user(self, email, password, **extra_fields): """
电子邮件
和密码
字段创建一个用户帐户。因此,my models.py中的自定义用户模型为:
我自定义UserManager以创建用户
from django.contrib.auth.models import BaseUserManager
class UserManager(BaseUserManager):
def _create_user(self, email, password, **extra_fields):
"""
Creates and saves a User with the given email and password.
"""
if not email:
raise ValueError("Users must have an email address")
email = self.normalize_email(email)
user = self.model(email = email, **extra_fields)
user.set_password(password)
user.save()
return user
def create_superuser(self, email, password, **extra_fields):
extra_fields.setdefault('is_staff', True)
extra_fields.setdefault('is_superuser', True)
extra_fields.setdefault('is_active', True)
if extra_fields.get('is_staff') is not True:
raise ValueError('Superuser must have is_staff=True.')
if extra_fields.get('is_superuser') is not True:
raise ValueError('Superuser must have is_superuser=True.')
return self._create_user(email, password, **extra_fields)
我的用户模型是:
from django.contrib.auth.models import AbstractBaseUser
from django.contrib.auth.models import PermissionsMixin
from django.utils.translation import ugettext_lazy as _
class User(AbstractBaseUser, PermissionsMixin):
email = models.EmailField(unique=True, null=True,
help_text=_('Required. Letters, digits and ''@/./+/-/_ only.'),
validators=[RegexValidator(r'^[\w.@+-]+$', _('Enter a valid email address.'), 'invalid')
])
is_staff = models.BooleanField(
_('staff status'),
default=False,
help_text=_('Designates whether the user can log into this site.'),
)
is_active = models.BooleanField(
_('active'),
default=True,
help_text=_(
'Designates whether this user should be treated as active. '
'Unselect this instead of deleting accounts.'
),
)
objects = UserManager()
USERNAME_FIELD = "email"
class Meta:
db_table = 'auth_user'
verbose_name_plural = 'Usuarios en la plataforma'
def __str__(self):
return "@{}".format(self.email)
在我的设置中,我添加了:
AUTH_USER_MODEL = ‘my_app_name.User’
创建用户-
用户创建表单
预构建类
要创建用户,我使用UserCreationForm
类
在这个类中使用username字段
根据上述内容,在我的forms.py中,我有:
from django.contrib.auth.forms import UserChangeForm, UserCreationForm
class CustomUserChangeForm(UserChangeForm):
class Meta(UserChangeForm.Meta):
model = get_user_model()
class CustomUserCreationForm(UserCreationForm):
class Meta(UserCreationForm.Meta):
model = get_user_model()
class UserCreateForm(UserCreationForm):
class Meta:
fields = ("email", "password1", "password2",)
model = get_user_model()
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields["email"].label = "Email address"
当我尝试执行python manage.py makemigrations时,我得到了这个回溯输出错误

如果有人能给我指出正确的方向,我将不胜感激。:) 我找到了一个有效的解决方案 无论如何,请随时提出更好的解决方案 比如,我的不便/错误与使用
UserCreationForm
类有关,然后我继续做以下工作:
在我的类CustomUserCreationForm
中的my forms.py是类UserCreationForm
的子类,我使用email
字段而不是username
字段,覆盖/添加到Meta
类的属性字段。
帮帮我
我的班级CustomUserCreationForm
停留如下:
class CustomUserCreationForm(UserCreationForm):
class Meta(UserCreationForm.Meta):
model = get_user_model()
fields = ('email',)
然后,我继续执行迁移:
[1] % python manage.py makemigrations accounts
SystemCheckError: System check identified some issues:
ERRORS:
<class 'accounts.admin.UserAdmin'>: (admin.E033) The value of 'ordering[0]' refers to 'username', which is not an attribute of 'accounts.User'.
通过这种方式,我执行迁移
bgarcial@elpug ‹ testing ●● › : ~/workspace/ihost_project
[1] % python manage.py makemigrations accounts
Migrations for 'accounts':
accounts/migrations/0001_initial.py:
- Create model User
(ihost)
bgarcial@elpug ‹ testing ●● › : ~/workspace/ihost_project
python manage.py migrate accounts ...
而且我的用户名字段仍然保留在我的自定义用户模式中,只是这不是必需的,当我从继承自UserCreationForm
的UserCreateForm
类中创建用户时,我可以创建一个仅使用电子邮件和密码的用户帐户
我不知道这是否是解决这一不便的最好办法。
