【问题描述】：
我有一个通过使用扩展 AbstractBaseUser 的自定义模型来扩展用户模型的代码。我收到此错误消息
(ERRORS: : (admin.E108) 的值 'list_display[2]' 指的是 'first_name'，它不是可调用的， “UserAdmin”的属性，或“towns.MyUser”的属性或方法。 : (admin.E108) 的值 'list_display[3]' 指的是 'last_name'，它不是可调用的， 'UserAdmin' 的属性，或 'towns.MyUser' 的属性或方法。
模型文件：
from django.contrib.auth.models import (
BaseUserManager, AbstractBaseUser
)
class MyUserManager(BaseUserManager):
def create_user(self, username, email, password=None):
if not email:
raise ValueError('email address is required')
user = self.model(
username = username,
email = self.normalize_email(email)
)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, username, email, password=None):
user = self.create_user(
username, email, password=password
)
user.is_admin = True
user.is_staff = True
user.save(using=self._db)
return user
class MyUser (AbstractBaseUser):
username = models.CharField(
max_length=255,
unique=True
)
email = models.EmailField(
max_length=255,
unique=True,
verbose_name='email address'
)
is_admin = models.BooleanField(default=False)
is_staff = models.BooleanField(default=False)
objects = MyUserManager()
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email']
表格文件：
from django.contrib.auth import get_user_model
from django.db.models import Q
User = get_user_model()
from django import forms
class UserCreationForm(forms.ModelForm):
password1 = forms.CharField(label='password', widget=forms.PasswordInput)
password2 = forms.CharField(label='password confirmation', widget=forms.PasswordInput)
class Meta:
model = User
fields = ['username', 'email']
def clean_password(self):
password1 = self.cleaned_data.get('password1')
password2 = self.cleaned_data.get('password2')
if password1 and password2 and password1 != password2:
raise forms.ValidationError("passwords do not match")
return password2
def save(self, commit=True):
user = super(UserCreationForm, self).save(commit=False)
user.set_password(self.cleaned_data['password1'])
if commit:
user.save()
return user
class UserLoginForm(forms.Form):
query = forms.CharField(label='Username or Email')
password = forms.CharField(label='Password',widget=forms.PasswordInput)
def clean(self, *args, **kwargs):
query = self.cleaned_data.get('query')
password = self.cleaned_data.get('password')
user_qs_final = User.objects.filter(
Q(username__iexact=query) |
Q(email__iexact=query).distinct()
)
if not user_qs_final.exists() and user_qs_final.count != 1:
raise forms.ValidationError('Invalid credentials = user does not exist')
user_obj = user_qs_final.first()
if not user.obj.check_password(password):
raise forms.ValidationError(' password is not correct')
self.cleaned_data["user_obj"] = user_obj
return super(UserLoginForm, self).clean(*args, **kwargs)
管理文件：
from django.contrib import admin
from django.contrib.auth.models import Group
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from .forms import UserCreationForm
from .models import MyUser
class UserAdmin(BaseUserAdmin):
add_form = UserCreationForm
List_display = ('username', 'email', 'is_admin')
list_filter = ('is_admin',)
fieldsets = (
(None, {'fields': ('username', 'email','password')}),
('Permissions', {'fields': ('is_admin',)}),
)
search_fields = ('username', 'email')
ordering = ('username','email')
filter_horizontal = ()
admin.site.register(MyUser,UserAdmin)
admin.site.unregister(Group)
我也将设置文件中的 AUTH_USER_MODEL 更改为
AUTH_USER_MODEL = 'towns.MyUser'
任何线索如何解决这个错误
注意：我并不真正需要这些字段 (first_name), (last_name)
