ProgrammingError：关系“account_account”不存在

Question

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

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makemigrations/migrate，它没有帮助。

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 也定义了：

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“account_account”存在！

但在此命令的输出中不是迁移“帐户”！

>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.

它看起来不像你的 makemigrations / migrate 运行，因为这告诉你该表不存在。

(1) 运行 makemigrations 和 migrate，并确保您使用正确的设置运行以在 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？
