我需要在我的应用程序中只使用email
和password
字段创建一个用户帐户。因此,我的自定义用户模型模型.py是:
我定制了UserManager来创建用户
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:
^{pr2}$在我的设置中,我添加了:
AUTH_USER_MODEL = ‘my_app_name.User’
创建用户-UserCreationForm
预建类
要创建用户,我使用UserCreationForm
类pre-built in the django core.
在这个类中,用户名字段使用such as denoted here
根据以上所述,在我的表单.py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时管理.pymakemigrations,我得到这个回溯输出错误

当然,我使用的是UserCreationForm
django类核心,我强制使用django核心功能,其中username字段是必需的
如何删除用户名或修改此用户名?在
我知道不建议修改django核心,但是,如何使用UserCreationForm
django类核心来创建一个不包含用户名字段的用户呢?在
我尝试在创建用户的地方重写表单的save方法,但是我没有明确的过程,我认为我不方便的核心是使用UserCreationForm
django类核心。。在
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"
def save(self, commit=True):
user = super(UserCreateForm, self).save(commit=False)
user.email = self.cleaned_data["email"]
# Tell to Django that not check the username
if commit:
user.save()
return user
如果有人能为我指出正确的方向,我将不胜感激。:)
我找到了一个有效的解决办法。在
不管怎样,请随时提出更好的解决方案!在
就像我的不方便/错误与使用
UserCreationForm
类pre-built in the django core有关,后者是{a2},然后我继续做以下工作:在我的表单.py在我的类中,
CustomUserCreationForm
是类UserCreationForm
的子类,我使用email
字段而不是username
字段重写/添加到Meta
类中。 This question post帮我。在我的班级
CustomUserCreationForm
保持如下状态:然后,我继续进行迁移:
^{pr2}$这个错误告诉我
username
字段不是我的User
模型的属性。 这意味着Django继续尝试询问username字段,即使我用email
字段覆盖了fields
值。在当然,这是逻辑的,因为我仍然继承自
UserCreationForm
类pre-built in the django core然后,我将
username
字段添加到具有null=True属性的用户模型中,这样,在创建用户帐户时不需要用户名:这样,我执行迁移
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
类创建用户时,我可以只使用电子邮件和密码创建一个用户帐户我不知道这是否是解决这个麻烦的最好办法。 随时提出改进建议!在
