python - OperationalError：没有这样的列，但列在任何地方都不存在
问题描述
我正在建立一个 Django 网站，我是一个相对初学者。但是，这个错误让我感到困惑，所以请让我知道可能发生了什么。
我收到一个错误
django.db.utils.OperationalError: no such column: metadata.id
但是在我的代码中没有 metadata.id，也没有在我使用的数据库中。所以我真的很困惑这是从哪里来的。
大概我在不应该的地方进行了修补。
那么我的问题是，这条消息的开头是否表明我应该在哪里寻找错误？
我也有这个消息
In template .../kinbank2/templates/base.html, error at line 0
这使得很难找到要查看的行或文件。
谢谢，
山姆

** 编辑 **
在 Roy 的搜索和帮助下，我认为这与模型以及它们是如何创建的有关？
当我转到文件 language/migrations/0001_initial.py 时，我有以下与我的模型相关的代码：
migrations.CreateModel(
name='Metadata',
fields=[
('id', models.AutoField(auto_created=True,primary_key=True, serialize=False, verbose_name='ID')),
('kinbank_id', models.TextField(blank=True, null=True, unique=True)),
('preferred_name', models.TextField(blank=True, db_column='Preferred_name', null=True)),
('language_family', models.TextField(blank=True, db_column='Language_Family', null=True)),
('latitude', models.TextField(blank=True, db_column='Latitude', null=True)),
('longitude', models.TextField(blank=True, db_column='Longitude', null=True)),
('glottolog_id', models.TextField(blank=True, db_column='Glottolog_id', null=True)),
('dplace_id', models.TextField(blank=True, db_column='DPLACE_id', null=True)),
('iso_code', models.TextField(blank=True, db_column='ISO_code', null=True)),
('status', models.TextField(blank=True, db_column='Status', null=True)),
('notes', models.TextField(blank=True, db_column='Notes', null=True)),
('url', models.TextField(blank=True, null=True)),
],
options={
'managed': False,
'db_table': 'metadata',
},
哪个似乎添加了我没有的 id 列？我应该做些什么来阻止这种情况吗？
