Django 经理是'；t可用'；授权用户'；已替换为'；成员。CustomUser'；

当我想要注册时，我的代码有问题。错误出现

管理器不可用；'“auth.User”已被“members.CustomUser”替换为“members.CustomUser”

，我尝试解决其他类似的问题，但所有问题都要求替换

User=User=get\u User\u model（）

，但我的代码中没有使用任何

User

，或者我不知道我在哪里使用了它。我是django、python、js等的新手，所以如果我的问题很傻，请原谅我

更多信息：1）我使用创建注册方法。首先，这很好，但在我扩展我的家庭作业项目后，我得到了错误。2）在其他应用程序（“产品”和“搜索”）中没有，我不导入用户，甚至我也不使用CustomUser。bez不需要在这个应用程序中与用户一起工作。只需

memebers

与用户和CustomUser一起工作即可

model.py：

from django.contrib.auth.models import AbstractUser



class CustomUser(AbstractUser):

    def __str__(self):
        return self.email

    class Meta:
        verbose_name = "member"
        verbose_name_plural = "members"

setting.py：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'card.apps.CardConfig',
    'members.apps.MembersConfig',
    'search.apps.SearchConfig',
    'products.apps.ProductsConfig',
    'rest_framework',
]

AUTH_USER_MODEL = 'members.CustomUser'

admin.py：

from django.contrib import admin
from django.contrib.auth import get_user_model
from django.contrib.auth.admin import UserAdmin

from .forms import CustomUserCreationForm, CustomUserChangeForm
from .models import CustomUser



class CustomUserAdmin(UserAdmin):
    add_form = CustomUserCreationForm
    form = CustomUserChangeForm
    model = CustomUser
    list_display = ['email', 'username']


admin.site.register(CustomUser, CustomUserAdmin)

form.py：

# users/forms.py
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from .models import CustomUser


class CustomUserCreationForm(UserCreationForm):
    class Meta(UserCreationForm):
        model = CustomUser
        fields = ('username', 'email')


class CustomUserChangeForm(UserChangeForm):
    class Meta:
        model = CustomUser
        fields = ('username', 'email')

在您的forms.py中进行以下更改：

from django.contrib.auth import get_user_model

class CustomUserChangeForm(UserChangeForm):
    class Meta:
        model = get_user_model()
        fields = ('username', 'email')

class CustomUserCreationForm(UserCreationForm):
    class Meta:
        model = get_user_model()
        fields = ('username', 'email')

还要将此脚本添加到您的members/init.py文件中：

    default_app_config = 'members.apps.MembersConfig'

修改视图.py

from django.contrib.auth.forms import UserCreationForm
from django.urls import reverse_lazy
from django.views import generic


class SignUp(generic.CreateView):
    form_class = UserCreationForm
    success_url = reverse_lazy('login')
    template_name = 'signup.html'

到

---

members

是您的应用程序名称吗？是

从django.apps导入AppConfig类MembersConfig（AppConfig）：name='members'

是否在

members/\uuuuu init\uuuuuu.py

中设置了

default\u app\u config

？不，我一生中从未在init.py中编辑任何内容。我检查它是否为空。获取错误：name'UserChangeForm'未定义。然后我从django.contrib.auth.forms导入UserCreationForm，UserChangeForm和旧问题仍然存在。您能在admin.py文件中添加这些表单并删除admin.py文件中这些表单的导入吗？正如您告诉我的，我更改了form.py和members/init.py，但仍然存在错误。关于“您能在admin.py文件中添加这些表单并删除admin.py文件中这些表单的导入吗”我不知道明白你的意思。你能给我留下代码吗？这是我在github上的作业。我认为这是发现问题的简单方法。。tnxI会看一看。

from .forms import CustomUserCreationForm
from django.urls import reverse_lazy
from django.views import generic


class SignUp(generic.CreateView):
    form_class = CustomUserCreationForm
    success_url = reverse_lazy('login')
    template_name = 'signup.html'
