我创建了一个新的 Django 项目,我做的第一件事就是在 Django 文档的帮助下创建一个自定义用户:https://docs.djangoproject.com/en/2.0/topics/auth/customizing/

在我为自定义用户编写了所有代码之后,并且在这个 Django 项目中第一次执行 ma​​kemigrationsmigrate 之后,我尝试创建一个 super 用户当我的虚拟环境通过以下方式处于事件状态时:

python manage.py createsuperuser

但它给了我这个错误:

TypeError: hasattr(): attribute name must be string

我在名为帐户的应用程序中编写了所有自定义用户代码。

设置文件中,我将“帐户”添加到 INSTALLED_APPS 列表中,并在底部添加了这一行:

AUTH_USER_MODEL = 'accounts.CustomUser'

这是我的所有源代码,从 models.py 开始:

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, PermissionsMixin


class CustomUserManager(BaseUserManager):

def create_user(self, email, password=None):

if not email:
raise ValueError("Users must have an email address")
if not password:
raise ValueError("Users must have a password")

user = self.model(
email = self.normalize_email(email)
)

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

return user


def create_staffuser(self, email, password, first_name, last_name):

if not first_name:
raise ValueError("Staff and superusers must have a first name")
if not last_name:
raise ValueError("Staff and superusers must have a last name")

user = self.create_user(
email,
password=password
)

user.first_name = first_name
user.last_name = last_name
user.is_staff = True
user.save(using=self._db)

return user


def create_superuser(self, email, password, first_name, last_name):

user = self.create_staffuser(
email,
password=password,
first_name=first_name,
last_name=last_name
)

user.is_admin = True
user.is_superuser = True
user.save(using=self._db)

return user


class CustomUser(AbstractBaseUser, PermissionsMixin):

email = models.EmailField(null=True, max_length=80, unique=True)
USERNAME_FIELD = 'email'
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
is_staff = models.BooleanField(default=False)
first_name = models.CharField(max_length=25, blank=True, null=True)
last_name = models.CharField(max_length=25, blank=True, null=True)
date_joined = models.DateField(auto_now_add=True, null=True)
REQUIRED_FIELDS = [first_name, last_name]

objects = CustomUserManager()

def __str__(self):
return self.email

def get_short_name():
return first_name

def get_full_name():
return first_name + ' ' + last_name

然后我在 forms.py 中写了这个:

from django import forms
from django.contrib.auth.forms import ReadOnlyPasswordHashField
from .models import CustomUser


class UserCreationForm(forms.ModelForm):
"""A form for creating new users. Includes all the required
fields, plus a repeated password."""
password1 = forms.CharField(label='Password', widget=forms.PasswordInput)
password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput)

class Meta:
model = CustomUser
fields = ('email', 'first_name', 'last_name')

def clean_password2(self):
# Check that the two password entries match
password1 = self.cleaned_data.get("password1")
password2 = self.cleaned_data.get("password2")
if password1 and password2 and password1 != password2:
raise forms.ValidationError("Passwords don't match")
return password2

def save(self, commit=True):
# Save the provided password in hashed format
user = super().save(commit=False)
user.set_password(self.cleaned_data["password1"])
if commit:
user.save()
return user


class UserChangeForm(forms.ModelForm):
"""A form for updating users. Includes all the fields on
the user, but replaces the password field with admin's
password hash display field.
"""
password = ReadOnlyPasswordHashField()

class Meta:
model = CustomUser
fields = ('email', 'password', 'first_name', 'last_name', 'is_active', 'is_admin')

def clean_password(self):
# Regardless of what the user provides, return the initial value.
# This is done here, rather than on the field, because the
# field does not have access to the initial value
return self.initial["password"]

在 admin.py 中:

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from .models import CustomUser
from .forms import UserCreationForm, UserChangeForm


class UserAdmin(BaseUserAdmin):
# The forms to add and change user instances
form = UserChangeForm
add_form = UserCreationForm

# The fields to be used in displaying the User model.
# These override the definitions on the base UserAdmin
# that reference specific fields on auth.User.
list_display = ('email', 'first_name', 'last_name', 'is_admin')
list_filter = ('is_admin',)
fieldsets = (
(None, {'fields': ('email', 'password')}),
('Personal info', {'fields': ('first_name', 'last_name',)}),
('Meta', {'fields': ('date_joined', 'last_login', 'is_active',)}),
('Permissions', {'fields': ('is_admin', 'is_staff',)}),
)
# add_fieldsets is not a standard ModelAdmin attribute. UserAdmin
# overrides get_fieldsets to use this attribute when creating a user.
add_fieldsets = (
(None, {
'classes': ('wide',),
'fields': ('email', 'first_name', 'last_name' 'password1', 'password2')}
),
)
search_fields = ('email', 'first_name')
ordering = ('email',)
filter_horizontal = ()

admin.site.register(CustomUser, UserAdmin)

这是整个错误回溯:

Traceback (most recent call last):
File "manage.py", line 15, in <module>
execute_from_command_line(sys.argv)
File "/home/howdidthishappen/Projects/project-root/project_env/lib/python3.6/site-packages/django/core/management/__init__.py", line 371, in execute_from_command_line

File "/usr/lib/python3.6/argparse.py", line 1760, in parse_known_args
if not hasattr(namespace, action.dest):
TypeError: hasattr(): attribute name must be string

最佳答案

此行不正确:

REQUIRED_FIELDS     = [first_name, last_name]

应该是:

REQUIRED_FIELDS     = ['first_name', 'last_name']

这就是为什么我有一个 TypeError 说“属性名称必须是字符串”。
