我按照heroku 文档安装了一个 django 应用程序，起初它运行良好。一天后，我将一些更改推送到服务器。之后，我根本无法访问该应用程序：FATAL: password authentication failed for user "drjstoymyqyarj"

我什至不能再同步数据库了：

$ heroku run python manage.py syncdb
Running `python manage.py syncdb` attached to terminal... up, run.1
Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)

    utility.execute()

    cursor = connection.cursor()

    cursor = self.make_debug_cursor(self._cursor())
  File "/app/.heroku/venv/lib/python2.7/site-packages/django/db/backends/postgresql_psycopg2/base.py", line 177, in _cursor
    self.connection = Database.connect(**conn_params)
  File "/app/.heroku/venv/lib/python2.7/site-packages/psycopg2/__init__.py", line 179, in connect
    connection_factory=connection_factory, async=async)
psycopg2.OperationalError: FATAL:  password authentication failed for user "drjstoymyqyarj"
FATAL:  password authentication failed for user "drjstoymyqyarj"

我使用了 heroku 文档中推荐的数据库设置：

import dj_database_url
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}

当我将代码推送到服务器后检查日志时，有一个Process exited with status 143我以前没有注意到的可疑之处。也许这与它有关？

$ heroku logs
heroku[web.1]: State changed from up to starting
heroku[web.1]: Stopping all processes with SIGTERM

与heroku pg:psql. 但是，我可以使用 Django 打开一个 Django shell heroku run python manage.py shell，但我无法从其中访问任何数据（当然也是同样的错误）。

对此的任何帮助表示赞赏。

跑

heroku config

并查看是否配置了 2 个以上的 heroku dbs，并查看 DATABASE_URL 是否指向您配置的数据库。如果没有，那么您可以通过运行将您的数据库提升为默认的 DATABASE_URL：

heroku pg:promote HEROKU_POSTGRESQL_GREEN

其中 HEROKU_POSTGRESQL_GREEN 是您的数据库名称，您将在配置中看到 HEROKU_POSTGRESQL_GREEN_URL。

一旦您配置的数据库升级为默认数据库，您就可以开始了。
