Tôi đang sử dụng mô hình người dùng tùy chỉnh ở Django. Mô hình hoạt động tốt và có thể tạo người dùng. Nhưng khi tôi cố gắng truy cập trang quản trị nó ném cho tôi những lỗiFieldError tại/admin/- (Các) trường không xác định (added_on) được chỉ định cho UserProfile
FieldError at /admin/
Unknown field(s) (added_on) specified for UserProfile
Các UserProfile có một thuộc tính added_on. Tôi không thể nghĩ ra bất kỳ lý do nào tại sao điều này lại hiển thị. Nếu tôi xóa thuộc tính added_on khỏi tệp admin.py, bảng quản trị sẽ hoạt động.
Đây là models.py tôi
from django.db import models
from django.contrib.auth.models import User, BaseUserManager, AbstractBaseUser
from django.conf import settings
class UserProfileManager(BaseUserManager):
def create_user(self, email, username, name, password=None):
if not email:
raise ValueError('Users must have an email address')
user = self.model(
username=username,
name=name,
email=self.normalize_email(email),
)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, email, username, name, password):
user = self.create_user(email=email,
password=password,
username=username,
name=name
)
user.is_admin = True
user.save(using=self._db)
return user
class UserProfile(AbstractBaseUser):
SHOPPER = 1
TECH_ENTHU = 2

class OldUser(models.Model):
old_user_id = models.BigIntegerField()
user = models.ForeignKey(settings.AUTH_USER_MODEL)
converted = models.BooleanField(default=False)
Đây là admin.py tôi

if password1 and password2 and password1 != password2:
raise forms.ValidationError("Passwords don't match")
return password2
def save(self, commit=True):
# Save the provided password in hashed format
user = super(UserCreationForm, self).save(commit=False)
user.set_password(self.cleaned_data["password1"])

'points', 'level', 'added_on', 'is_active', 'is_admin')
def clean_password(self):
# Regardless of what the user provides, return the initial value.
# This is done here, rather than on the field, because the
# field does not have access to the initial value
return self.initial["password"]

# The fields to be used in displaying the User model.

fieldsets = (

để hiển thị trường auto_now_add (chỉ đọc) trong quản trị viên, bạn phải thêm trường đó vào cả hai trường readnd của trường read_only_field. – wardk
