在 Django admin

如何解决在 Django admin

我创建了一个扩展 AbstractUser 的自定义模型，以便通过电子邮件代替用户名来验证用户（但不想删除用户名，因为它也会被使用）。

这是我在运行第一次迁移之前所做的第一件事，除了在 Django 管理员中，一切正常，当我创建一个新用户时，我希望填充这些字段 用户名 电子邮件 密码

管理员只问我用户名和密码。我怎样才能添加电子邮件？这是我的代码

models.py

from django.db import models
from django.contrib.auth.models import AbstractUser
from django.contrib.auth.base_user import BaseUserManager
from django.utils.translation import ugettext_lazy as _


class CustomUserManager(BaseUserManager):
    """
    Custom user model manager where email is the unique identifier for 
    authentication instead of username.
    """
    def create_user(self,email,password,**extra_fields):
        """
        Create and save a User with the given email and password.
        """
        if not email:
            raise ValueError(_('The Email must be set'))
        email = self.normalize_email(email)
        user = self.model(email=email,**extra_fields)
        user.set_password(password)
        user.save()
        return user
    
    def create_superuser(self,**extra_fields):
        """
        Create and save a SuperUser with the given email and password.
        """
        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,**extra_fields)


class User(AbstractUser):
    email = models.EmailField(_('email address'),unique=True)
    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []
    objects = CustomUserManager()

    def __str__(self):
        return self.email

admin.py

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .models import User as CustomUser


class CustomUserAdmin(UserAdmin):
    model = CustomUser
    list_display = ('email','is_staff','is_active',)
    list_filter = ('eamil',)
    fieldsets = (
        (None,{'fields': ('email','password')}),('Permissions',{'fields': ('is_staff','is_active')}),)
    add_fieldsets = (
        (None,{
            'classes': ('wide',),'fields': ('email','password1','password2','is_active')}
        ),)
    search_fields = ('email',)
    ordering = ('email',)

admin.site.register(CustomUser,UserAdmin)

我该怎么办？似乎一切都正确，但缺少所需的电子邮件字段。请注意，这仅在我使用管理员中的添加用户功能时发生。当我创建超级用户或登录管理员时，一切都按预期工作。

更新： 这是我的 forms.py 的内容

from django.contrib.auth.forms import UserCreationForm
# the user model was customized it should be invoked
from django.contrib.auth import get_user_model
from django.contrib.auth import forms as auth_forms
from .models import User as CustomUser


class UserChangeForm(auth_forms.UserChangeForm):
    class Meta(auth_forms.UserChangeForm.Meta):
        model = CustomUser

class UserCreationForm(auth_forms.UserCreationForm):
    class Meta(auth_forms.UserCreationForm.Meta):
        model = CustomUser
        fields = ("username","email")


class CustomUserCreationForm(UserCreationForm):
    class Meta(UserCreationForm.Meta):
        # the user model was customized it should be invoked
        model = get_user_model()
        fields = UserCreationForm.Meta.fields + ("email",)

这里是我的 admin.py 的内容（更新）

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

class CustomUserAdmin(UserAdmin):
    model = CustomUser
    list_display = ('email','username',)
    form = UserChangeForm
    add_form = UserCreationForm
    
    fieldsets = (
        (None,UserAdmin)

但是我还是有同样的问题，我仍然无法在/admin/users/user/add/中添加电子邮件字段

解决方法

UserAdmin 类具有属性 form 和 add_form，它们分别指向用于编辑和创建用户的表单类。您需要覆盖这些表单类并自己设置这些属性，因为这两个表单是为默认用户模型创建的。

首先定义这些自定义表单：

from django.contrib.auth import forms as auth_forms
from .models import User as CustomUser

class UserChangeForm(auth_forms.UserChangeForm):
    class Meta(auth_forms.UserChangeForm.Meta):
        model = CustomUser


class UserCreationForm(auth_forms.UserCreationForm):
    class Meta(auth_forms.UserCreationForm.Meta):
        model = CustomUser
        fields = ("username","email")

接下来在您的 CustomUserAdmin 中设置这些：

from .forms import UserChangeForm,UserCreationForm


class CustomUserAdmin(UserAdmin):
    # Your other attributes here
    form = UserChangeForm
    add_form = UserCreationForm
