Django：没有这样的表：users_profile

Question

这里是 Django 菜鸟。每当我扩展基本用户模型并尝试访问或编辑新字段时，我都会收到以下错误 [... table not found]。

OperationalError at /admin/users/profile/
no such table: users_profile
Request Method: GET
Request URL:    http://127.0.0.1:8000/admin/users/profile/

我不确定为什么会发生这种情况，因为我已经运行了 makemigrations 并多次迁移。以下是我的迁移供参考

from django.conf import settings
from django.db import migrations, models
import django.db.models.deletion


class Migration(migrations.Migration):

    initial = True

    dependencies = [
        migrations.swappable_dependency(settings.AUTH_USER_MODEL),
    ]

    operations = [
        migrations.CreateModel(
            name='Profile',
            fields=[
                ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
                ('profile_picture', models.ImageField(default='default.jpg', upload_to='profile_pictures')),
                ('user', models.OneToOneField(on_delete=django.db.models.deletion.CASCADE, to=settings.AUTH_USER_MODEL)),
            ],
        ),
    ]

还有我的models.py供进一步参考

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

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    profile_picture = models.ImageField(default = 'default.jpg', upload_to = 'profile_pictures') 

    def __str__(self):
        return f'{self.user.username} Profile' 

另外值得注意的是，在尝试更改管理站点中的配置文件表时会出现此问题

如果您需要了解其他信息，请告诉我。

感谢您的帮助:)

尝试从您的应用中删除migrations 文件夹和db.sqilte3 文件，然后重试-：

python manage.py makemigrations

python manage.py migrate

python manage.py createsuperuser

然后重试你的错误必须解决
