我在我的本地机器上有一个工作安装，但无法在 heroku 上做同样的事情。

我所做的唯一更改：

  • 将 firefly.yml 中的主机名更改为 rxlcc.herokuapp.com
  • 注释掉 Gemfile 中的其他 dbs，只有 pg 未注释

我的回购地址：https ://github.com/hayksaakian/rxlcc

github变更日志：https ://github.com/hayksaakian/rxlcc/commit/d2e2f926b228372a9ff7861e918bdf193a3c3bca

我猜这是因为没有与生产数据库的连接，但我不确定我会在哪里添加它们

我的heroku插件：

heroku-postgresql:dev  HEROKU_POSTGRESQL_NAVY

更新：

我尝试在 lib/firefly/server.rb 中添加一行

  # suggested by iain on stackoverflow
  @config[:database_url] = ENV["DATABASE_URL"]

这似乎并没有改变任何东西

是的，您需要host:在 yml 文件的 under 中指定数据库 url。您可以在 Heroku 站点的设置页面中查看 url，也可以运行heroku config --app rxlcc并查找 DATABASE_URL。

注意：如果您要使用 Heroku，说明会告诉您更改 .gitignore 并签入 .yml 文件。如果您要在其中保留密钥，那么我不会这样做，但如果您这样做，请不要将回购公开！如果其他人知道秘密，您需要重新生成它。

我个人会通过添加任何秘密

heroku config:add SECRET_VARIABLE=blahblahblah --app rxlcc

然后将其读入需要通过的应用程序

my_secret_variable = ENV["SECRET_VARIABLE"]

我看到该应用程序在https://github.com/hayksaakian/rxlcc/blob/master/lib/firefly/server.rb#L209和https://github.com/hayksaakian/rxlcc的前块中设置了配置/blob/master/lib/firefly/server.rb#L109。在任何一点上，您都可以尝试：

@config[:database_url] = ENV["DATABASE_URL"]

添加任何秘密变量。
