Django FieldError：指定了未知字段（usable_password）

  • 772

我在管理面板中的用户中尝试添加用户时遇到了这个 FieldError。当我单击添加用户时，会弹出此错误。我从未在代码的任何地方使用过 usable_password，并尝试了多种方法来解决此问题，方法是删除 db.sqlite3、迁移，然后重新执行 makemirations。还有一件事是我更改了 models.py 中类的拼写（执行迁移后再次执行迁移，成功创建了迁移文件）。我想了解为什么会发生这种情况，还有一件事，不久前我在另一个项目中遇到过类似的错误，我不知道那次是如何解决的。 FieldError at /admin/accounts/customuser/add/ Unknown field(s) (usable_password) specified for CustomUser. Check fields/fieldsets/exclude attributes of class CustomUserAdmin. Request Method: GET Request URL: http://127.0.0.1:8000/admin/accounts/customuser/add/ Django Version: 5.1.4 Exception Type: FieldError Exception Value: Unknown field(s) (usable_password) specified for CustomUser. Check fields/fieldsets/exclude attributes of class CustomUserAdmin. Exception Location: C:\Users\Learning Django\blog-api\.venv\Lib\site-packages\django\contrib\admin\options.py, line 841, in get_form Raised during: django.contrib.auth.admin.add_view Python Executable: C:\Users\Learning Django\blog-api\.venv\Scripts\python.exe Python Version: 3.12.2 Python Path: ['C:\\Users\\Desktop\\Learning ' 'Django\\blog-api\\django_project', 'C:\\Python312\\python312.zip', 'C:\\Python312\\DLLs', 'C:\\Python312\\Lib', 'C:\\Python312', 'C:\\Users\\Learning ' 'Django\\blog-api\\.venv', 'C:\\Users\\Learning ' 'Django\\blog-api\\.venv\\Lib\\site-packages']

我附上了 models.py、forms.py 和 admin.py 的代码：models.py

from django.db import models

# Create your models here.
from django.contrib.auth.models import AbstractUser

class CustomUser(AbstractUser):
    name = models.CharField(null = True, blank = True, max_length = 255)

表单.py

from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from .models import CustomUser


class CustomUserCreationForm(UserCreationForm):
    class Meta(UserCreationForm):
        model = CustomUser
        fields = UserCreationForm.Meta.fields + ('name',)
        
class CustomUserChangeForm(UserChangeForm):
    class Meta:
        model = CustomUser
        fields = UserChangeForm.Meta.fields

管理工具

from django.contrib import admin

# Register your models here.
from django.contrib.auth.admin import UserAdmin

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

class CustomUserAdmin(UserAdmin):
    add_form = CustomUserCreationForm
    change = CustomUserChangeForm
    model = CustomUser
    list_display = [
        "email",
        "username",
        "name",
        "is_staff",
    ]
    fieldsets = UserAdmin.fieldsets + ((None, {"fields": ("name",)}),)
    add_fieldsets = UserAdmin.add_fieldsets + ((None, {"fields": ("name",)}),)
admin.site.register(CustomUser, CustomUserAdmin)

    Django 分别使用AdminUserCreationForm和AdminPasswordChangeForm表示add_form和change_password_form。

    这些表单允许将密码设置为不可用。例如，这样做是为了防止用户使用密码登录（但例如使用 OTP 或通过其他方式）。

    因此，您可以混合使用以下形式UserAdmin：

    from django.contrib.auth.forms import AdminUserCreationForm


class CustomUserCreationForm(AdminUserCreationForm):
    class Meta(UserCreationForm):
        model = CustomUser
        fields = AdminUserCreationForm.Meta.fields + ('name',)
