ProgrammingError:关系"account_account“不存在

Question

我使用django-user-account==2.1.0改进了注册表。在我的本地服务器上一切正常，但在heroku服务器上我看到了以下错误：

Django Version: 2.2.6
Exception Type: ProgrammingError
Exception Value:    
relation "account_account" does not exist
LINE 1: ...nt"."timezone", "account_account"."language" FROM "account_a...
Exception Location: /app/.heroku/python/lib/python3.6/site-packages/django/db/backends/utils.py in _execute, line 84

我删除了数据库并再次进行了移民/迁移，但没有任何帮助。

我的settings.py的相关部分：

import dj_database_url
db_config = dj_database_url.config()
if db_config:
    DATABASES['default'] =  db_config

迁移命令的输出：

Operations to perform:
  Apply all migrations: account, admin, auth, contenttypes, sessions, my_apps, sites
Running migrations:
  No migrations to apply.

DATABASE_URL还定义了：

heroku config
=== Config Vars
DATABASE_URL:        postgres://bvki...longrul

这里我尝试获取表"account_account"：

>manage.py dbshell
SQLite version 3.30.1 2019-10-10 20:19:45
sqlite> SELECT * FROM "account_account";
1||1|lt
2||2|en

在sqlite中存在"account_account“！

但在此命令的输出中不是迁移"account"！

>heroku run python manage.py migrate
Running python manage.py migrate on ⬢ my-app... up, run.5012 (Free)
Operations to perform:
  Apply all migrations: admin, auth, contenttypes, sessions, my_app
Running migrations:
  No migrations to apply.
  Your models have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

看起来您的makemigrations / migrate并没有运行，因为它告诉您该表不存在。

(1)运行makemigrations和migrate，并确保您使用正确的设置在Heroku服务器上运行它。(2)使用您对Heroku服务器的设置运行python manage.py dbshell，并查看存在的表(PostgreSQL中的\dt)。account_account存在吗？
