Heroku 和 Django - 关系不存在

【中文标题】Heroku 和 Django - 关系不存在

【英文标题】：Heroku and Django - relation does not exist

【发布时间】：2018-07-16 14:50:02

【问题描述】：

我在 Heroku 上启动了一个应用程序，运行 Django 2.0.1，并提供了 Postgres 资源。我的 Procfile，经过几次迭代，看起来像这样：

过程文件

release: python manage.py migrate --noinput
web: gunicorn app.wsgi --log-file -

当我从 GitHub 部署时（不是从命令行部署...我之前没有从命令行部署，因为 GitHub 部署工作对我来说至关重要）一切正常。迁移按应有的方式运行，并且日志确认迁移时没有错误。事实上，部署到 Heroku 完全没有错误。

当我启动网站（强制它进入调试模式以查看错误）时，我在首页收到此错误：

ProgrammingError at /
relation "posts_post" does not exist
LINE 1: SELECT COUNT(*) AS "__count" FROM "posts_post" INNER JOIN "u...

尝试加载管理站点时存在类似错误：

ProgrammingError at /admin/login/
relation "django_site" does not exist
LINE 1: ..."django_site"."domain", "django_site"."name" FROM "django_si...
                                                             ^

我按照Django: relation "django_site" does not exist 中的建议先迁移sites，但没有任何效果。

另外，this issue on GitHub is related，但没有帮助。

为了澄清，该应用程序是可访问的。 Heroku 部署不会失败。该应用程序只是出错了。

Traceback:

The above exception (relation "posts_post" does not exist

                                          ^

为什么会出现这些错误？我该怎么做才能让我在 Heroku 上部署的 Django 正常工作？

【问题讨论】：

显示您的数据库设置。你在使用 Heroku Postgres 插件吗？

@DanielRoseman 添加了 settings.py sn-p

我也有同样的问题。每个迁移都在本地工作。但是，一旦我尝试在 heroku 上迁移某些东西，它就会由于我的“xyz_user”关系而失败。部署也有效。

你们是如何解决这个问题的？

【参考方案1】：

尝试运行

$Heroku run python manage.py migrate

在您的终端中。
