Django：为用户指定的未知字段（头像）

Question

所以我有这个模型

from django.db import models
from django.conf import settings

# Create your models here.

class ProfileImage(models.Model):
    user = models.OneToOneField(
        settings.AUTH_USER_MODEL,
        on_delete=models.CASCADE,
        editable=False
    )
    avatar = models.ImageField()
    
    def user_avatar(self):
       return self.profileimage.avatar

还有我的 admin.py

from django.contrib import admin

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

UserAdmin.fieldsets += ('Custom fields set', {'fields': ('avatar',)}),

我正在使用 User 模型，并向其中添加了一个图像字段，但我想在管理页面中查看图像字段，因此在 admin.py 中执行了该操作，但是当我进入用户管理员时出现此错误：

Unknown field(s) (avatar) specified for User. Check fields/fieldsets/exclude attributes of class UserAdmin.

Answer 1

您应该尝试更改您的管理代码，并进行一些建模，试试这个： 模型.py

class Profile(models.Model):
    user = models.OneToOneField(
        verbose_name=_('User'),
        to=settings.AUTH_USER_MODEL,
        related_name='profile',
        on_delete=models.CASCADE
    )
    avatar = models.ImageField()

和 admin.py

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

from accounts.models import ProfileImage

User = get_user_model()


class ProfileInline(admin.StackedInline):
    model = ProfileImage
    max_num = 1
    can_delete = False

class MyUserAdmin(UserAdmin):
    inlines = [ProfileInline]

# unregister old user admin
admin.site.unregister(User)
admin.site.unregister(Group)

# register new user admin that includes a UserProfile
admin.site.register(User, MyUserAdmin)

您的代码应如下所示 更新 模型.py

from django.contrib.auth.models import User
from django.db import models

class ProfileImage(models.Model):
      user = models.OneToOneField(User,
      on_delete=models.CASCADE,
      editable=False)
      avatar = models.ImageField()

     def user_avatar(self):
            return self.profileimage.avatar

User.add_to_class('user_avatar', user_avatar)

admin.py

UserAdmin.fieldsets += ('Custom fields set', {'fields': ('user_avatar',)}),
