Python &引用；django.db.utils.ProgrammingError:x字段不存在；在我删除模型字段后显示

我从我的

Post

模型中删除了

total_comments

字段。我在本地服务器上执行了

migrate

和

makemigrations

，将迁移文件推送到远程服务器，然后在那里也执行了

migrate

和

makemigrations

。但是，我现在在远程服务器终端中看到此错误：

我在

myapp/post/migrations

中查看了我的迁移文件夹，它显示迁移文件肯定在那里：

class Migration(migrations.Migration):

    dependencies = [
        ('post', '0031_auto_20180804_0724'),
    ]

    operations = [
        migrations.RemoveField(
            model_name='post',
            name='total_comments',
        ),
    ]

那么，为什么我仍然会遇到这个错误……有什么想法吗？

错误发生在我的芹菜任务上，该任务涉及处理我的

Post

模型（尽管芹菜任务文件没有处理

总注释

）

我重新启动了芹菜服务器，现在错误消失了
