当我展开我的用户管理员时，我在管理面板中收到一个错误(__init__() 有一个意外的关键字参数"区域")

Question

我正在按照教程 https://codingwithmitch.com/courses/building-a-website-django-python/构建一个使用 Django 2.2 的用户注册应用程序。 当我想在管理面板中添加新用户或修改一个用户时，我的网站运行良好。 这是我得到的回溯：

这是我 models.py：

from django.db import models
from phonenumber_field.modelfields import PhoneNumberField
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager

class MyAccountManager(BaseUserManager):
def create_user(self, username, email, first_name, last_name, password=None):
if not username:
return ValueError("وارد نمودن شماره تلفن همراه الزامیست")
if not email:
return ValueError("وارد نمودن ایمیل الزامیست")
if not first_name:
return ValueError("وارد نمودن نام الزامیست")
if not last_name:
return ValueError("وارد نمودن نام خانوادگی الزامیست")
user = self.model(
email=self.normalize_email(email),
username=username,
first_name=first_name,
last_name=last_name,
)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, username, email, first_name, last_name, password):
user = self.create_user(
email=self.normalize_email(email),
password=password,
username=username,
first_name=first_name,
last_name=last_name,
)
user.is_admin = True
user.is_staff = True
user.is_superuser = True
user.save(using=self._db)
return user

class Account(AbstractBaseUser):
username = PhoneNumberField(verbose_name='شماره تلفن همراه', max_length=15, blank=False, unique=True, region='IR')
first_name = models.CharField(verbose_name='نام', max_length=15)
last_name = models.CharField(verbose_name='نام خانوادگی', max_length=40)
email = models.EmailField(verbose_name='ایمیل', max_length=60, unique=True)
date_joined = models.DateTimeField(verbose_name='تاریخ ملحق شدن', auto_now_add=True)
last_login = models.DateTimeField(verbose_name='آخرین بازدید', auto_now=True)
is_admin = models.BooleanField(default=False)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
is_superuser = models.BooleanField(default=False)
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email', 'first_name', 'last_name', ]
objects = MyAccountManager()
def __str__(self):
return str(self.username) + ', ' + self.email
def has_perm(self, perm, obj=None):
return self.is_admin
def has_module_perms(self, app_label):
return True

我 admin.py：

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from account.models import Account

class AccountAdmin(UserAdmin):
list_display = ('username', 'email', 'date_joined', 'last_login', 'is_admin', 'is_staff')
search_fields = ('username', 'email',)
readonly_fields = ('date_joined', 'last_login')
filter_horizontal = ()
list_filter = ('is_staff',)
fieldsets = ()

admin.site.register(Account, AccountAdmin)

我 forms.py：

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth import authenticate
from phonenumber_field.formfields import PhoneNumberField
from phonenumber_field.widgets import PhoneNumberInternationalFallbackWidget
from account.models import Account

class RegistrationForm(UserCreationForm):
username = PhoneNumberField(help_text='این بخش الزامیست. لطفا شماره تلفن همراهتان را وارر نمایید',
label='شماره تلفن همراه', region='IR')
email = forms.EmailField(max_length=60, help_text='این بخش الزامیست. لطفا ایمیاتان را وارر نمایید', label='ایمیل')
class Meta:
model = Account
fields = ('username', 'email', 'first_name', 'last_name', 'password1', 'password2')

class AccountAuthenticationForm(forms.ModelForm):
username = PhoneNumberField(label='شماره تلفن همراه', widget=PhoneNumberInternationalFallbackWidget, region='IR')
password = forms.CharField(label='گذرواؤه', widget=forms.PasswordInput)
class Meta:
model = Account
fields = ('username', 'password')
def clean(self):
username = self.cleaned_data['username']
password = self.cleaned_data['password']
if not authenticate(username=username, password=password):
raise forms.ValidationError('اطلاعات وارد شده صحیح نمیباشد')

当我将 admin.py 更改为：

from django.contrib import admin
from account.models import Account

admin.site.register(Account)

它工作得很好，但是当我将其更改回原来的样子时，它会给我这个错误。 问题出在我的管理员或模型中吗？

Answer 1

我必须升级到django-phonenumber-field==3.0.1才能修复它。

Answer 2

我知道现在回答这个问题为时已晚，但以防万一以后有人可能会遇到同样的问题。

当我尝试使用PhoneNumberField作为默认用户名时，我遇到了同样的问题。

在admin.py中，AccountAdmin类继承了UserAdmin的属性。

当你运行http://127.0.0.1:8000/admin/account/account/1/change/时，UserAdmin类实现一个表单django.contrib.auth.forms.UserChangeForm。

此窗体包含一个内置的自定义模型字段UsernameField。最好将此字段替换为UserChangeForm中的phonenumber_field.formfields.PhoneNumberField.

同样，UserCreationForm中也有UsernameField。您还需要替换它。

为此，您必须实现您的自定义UsernameField.

将您的admin.py替换为以下代码：

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from account.models import Account
import phonenumber_field
from django.contrib.auth.forms import UserChangeForm, UserCreationForm
from django.contrib.auth.admin import UserAdmin
# Overriding inbuilt forms.UsernameField with formfields.PhoneNumberField
class UsernameField(phonenumber_field.formfields.PhoneNumberField):
def widget_attrs(self, widget):
return {
**super().widget_attrs(widget),
"autocapitalize": "none",
"autocomplete": "username",
}


class AccountAdmin(UserAdmin):
form = UserChangeForm
# Overriding UsernameField with Custom field
form.Meta.field_classes['username'] = UsernameField
add_form = UserCreationForm
# Overriding UsernameField with Custom field
add_form.Meta.field_classes['username'] = UsernameField
list_display = ('username', 'email', 'date_joined', 'last_login', 'is_admin', 'is_staff')
search_fields = ('username', 'email',)
readonly_fields = ('date_joined', 'last_login')
filter_horizontal = ()
list_filter = ('is_staff',)
fieldsets = ()

admin.site.register(Account, AccountAdmin)

现在它会正常工作。
