我有一个Profile模型，通过与User模型一对一的关系来定制User模型，该模型的代码如下
class Profile(models.Model):
user = models.OneToOneField(User, parent_link=True, on_delete=models.CASCADE)
bio = models.TextField()
slug = models.SlugField(unique=True, blank=True)
avatar_thumbnail = ProcessedImageField(upload_to='images/',
default='/images/default.png',
processors=[ResizeToFill(300, 300)],
format='JPEG',
options={'quality': 60})
location = models.TextField()
tags = models.ManyToManyField(Tag)
contact_information = models.TextField()
verified = models.BooleanField(default=False)
counter = models.IntegerField(default=0)
def __str__(self):
return self.user.username
def save(self, *args, **kwargs):
print('self.username')
print(self.user.username)
self.slug = self.user.username
super(Profile, self).save(*args, **kwargs)
def get_absolute_url(self):
return reverse('infrastructure:edit-user-profile', kwargs={'slug': self.slug})
每当我使用以下命令进入外壳时
python manage.py shell
并获取配置文件查询集
Profile.objects.all()
我得到了错误
AttributeError: 'Profile' object has no attribute 'password'
，每当我进入管理面板并单击“个人资料”部分时 我在说同样的事情时遇到同样的错误
怎么了？
我的admin.py代码
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import User
# Register your models here.
from . import models
class SubjectTagAdmin(admin.TabularInline):
model = models.SubjectTag.tags.through
class TagAdmin(admin.ModelAdmin):
inlines=[SubjectTagAdmin, ]
admin.site.register(models.Tag, TagAdmin)
admin.site.register(models.SubjectTag)
admin.site.register(models.Profile)
admin.site.register(models.Organization)
编辑
现在，只有在到达配置文件的UpdateView或从管理面板对其进行编辑时，我才会收到错误消息
