Django Table已经存在

Question

这是我的Django迁移文件。当我跑步

python manage.py makemigrations/migrate 

我得到这个错误。

Error:-

    django.db.utils.OperationalError: (1050, "Table 'tickets_duration' already exists")

我删除了数据库并运行它，但仍然遇到相同的错误。

class Migration(migrations.Migration):

    dependencies = [
    ]

    operations = [
        migrations.CreateModel(
            name='Duration',
            fields=[
                ('Id', models.UUIDField(primary_key=True, db_column=b'duration_id', default=uuid.uuid4, serialize=False, editable=False)),
                ('duration', models.CharField(max_length=200, db_column=b'duration')),

Answer 1

尝试一下python manage.py migrate your_app --fake。这篇文章谈论它。Django South-table已经存在。

Answer 2

python manage.py migrate --fake-initial应该适用于 django 2.2
