我收到以下OperationError当我尝试添加一个新的职位使用我的超级用户在管理网站。

OperationalError at /admin/blog/post/add/

table blog_post has no column named author_id

Request Method:     POST
Request URL:    http://127.0.0.1:8000/admin/blog/post/add/
Django Version:     4.2.1
Exception Type:     OperationalError
Exception Value:    

table blog_post has no column named author_id

我肯定我在我的www.example.com中做错了什么models.py这是我为这个表创建的类

class Post(models.Model):

    class Status(models.TextChoices):
        DRAFT = 'DF', 'Draft'
        PUBLISHED = 'PB', 'Published'

    title = models.CharField(max_length = 250)
    slug = models.SlugField(max_length=250)
    author = models.ForeignKey(User,
                               on_delete=models.CASCADE,
                               related_name='blog_posts')
    body = models.TextField()
    publish = models.DateTimeField(default=timezone.now)
    created = models.DateTimeField(auto_now_add = True)
    updated = models.DateTimeField(auto_now=True)
    status = models.CharField(max_length=2,
                              choices=Status.choices,
                              default=Status.DRAFT)

    class Meta:
        ordering = ['-publish']
        indexes = [
            models.Index(fields=['-publish']),
        ]

    def __str__(self) -> str:
        return self.title

我只是设置了admin.py和settings.py来识别这个类，数据库迁移完成了，但是错误仍然存在。
迁移文件：

from django.db import migrations, models
import django.utils.timezone

class Migration(migrations.Migration):

    initial = True

    dependencies = [
    ]

    operations = [
        migrations.CreateModel(
            name='Post',
            fields=[
                ('id', models.BigAutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
                ('title', models.CharField(max_length=250)),
                ('slug', models.SlugField(max_length=250)),
                ('body', models.TextField()),
                ('publish', models.DateTimeField(default=django.utils.timezone.now)),
                ('created', models.DateTimeField(auto_now_add=True)),
                ('updated', models.DateTimeField(auto_now=True)),
                ('status', models.CharField(choices=[('DF', 'Draft'), ('PB', 'Published')], default='DF', max_length=2)),
            ],
            options={
                'ordering': ['-publish'],
                'indexes': [models.Index(fields=['-publish'], name='blog_post_publish_bb7600_idx')],
            },
        ),
    ]

以下是python的结果manage.py showmigrations
