确保您拥有生产数据库的方法是使用，它应作为Heroku应用程序仪表板中的标准配置
如果需要将Heroku postgres db添加到仪表板中，只需
db进入仪表板后，单击它&它应该会出现Postgres界面。你可以看到；您应该在应用程序的仪表板中使用Postgress插件提供的详细信息
通常，与Heroku兼容的数据库.yml
如下所示：
#config/database.yml
production:
adapter: postgresql
encoding: utf8
database: *********
pool: 5
username: ********* #-> *** data from heroku's postgres user details page
password: ******
host: ******
你必须修改你的文件
您可以随时查看。尝试重新启动Heroku应用程序Heroku restart-a App\u name
，以供参考。通常情况下，您不必在heroku上进一步配置PG数据库（到目前为止都是OMR）。检查迁移情况，如果需要，因为您正在进行一个过程，您可以删除并再次创建数据库。已经尝试了，但仍然得到相同的错误页面。您可以将您要推送到heroku的github repo发布吗？是的，这里是：您的gemfile未更新！我不确定应该如何修改config/database.yml文件。你能在这方面再进一步吗？Zauzaj已经发布了你需要包含在文件中的内容；关于内容，您可以从Heroku获得您的数据库详细信息。如果你具体的话，我可以多写一点？好的，@zauzaj写道产品：适配器：postgresql编码：utf8数据库：你的数据库\u名称池：5用户名：postgres\u用户名密码：postgres\u密码主机：127.0.0.1
。但是，我不知道我的数据库名称和用户名/密码。我正在关注一个在线教程，我们还没有玩过任何db。好吧，我的道歉-我的意思是你在制作部分的结构是他写的。就实际数据而言，最好的方法是获取Heroku Postgres DB并使用它。如果你愿意，我可以指导你完成这个过程？太棒了。我使用git push heroku master推送我的rails应用程序，现在它可以工作了。我再也看不到“应用程序错误”页面了。谢谢你，伙计！！
