无法删除django中的超级用户并导致错误django.db.utils.OperationalError：无此类列：Infrastructure_profile.slug [英] Can not delete superuser in django and a resulting error django.db.utils.OperationalError: no such column: infrastructure_profile.slug

问题描述

我想在创建了多个配置文件后向我的模型配置文件（扩展用户模型）添加一个子段字段，然后进入配置文件页面时出现错误，URL中的子段显示：

I wanted to add a slug field to my model Profile (that extends the User model) after I had several profiles created, then an error appeared when reaching the profile page with the slug in the url saying :

Django OperationalError: no such column: infrastructure_profile.slug

所以我在这里看到了此答案

so I looked here and saw this answer

，它建议我删除所有迁移文件以重新启动数据库，所以我做了

and it suggested I delete all my migrations files to restart the database , so I did

，然后出现了同样的错误，所以我认为我应该删除我已经拥有的所有没有超级用户字段的用户。

and then I got the same error , so I thought I should delete all the users I already have that didn't had the slug field already including the superuser.

所以我关注了这个答案

我遇到了这个错误

django.db.utils.OperationalError: no such column: infrastructure_profile.slug

任何想法

编辑

我的models.py包含模型配置文件像这样

My models.py contains the model Profile like so

class Profile(User):
    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})

推荐答案

我不应该从User模型继承Profile，而是应该按照此答案将用户自定义为

I shouldn't have inherited Profile from the User model and I should have customized the user to following this answer instead
