在Heroku上設置Firefly（ruby link shortener）2.0？

我在本地機器上安裝了一個工作，但在heroku上無法做到這一點。在Heroku上設置Firefly（ruby link shortener）2.0？

我所做的唯一變化：firefly.yml

改變主機名rxlcc.herokuapp.com
註釋掉的Gemfile其他DBS，只有控球后衛註釋掉

我回購在：https://github.com/hayksaakian/rxlcc

github上的changelog：https://github.com/hayksaakian/rxlcc/commit/d2e2f926b228372a9ff7861e918bdf193a3c3bca

我猜這是因爲有生產數據庫沒有任何連接，但我不能確定這裏我想補充他們

我的Heroku插件：

heroku-postgresql:dev HEROKU_POSTGRESQL_NAVY

更新：

我嘗試添加在LIB線/螢火蟲/ server.rb

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

這似乎並沒有改變任何東西

是的，你需要指定數據庫的URL中host:下的YML文件。您可以在Heroku站點的設置頁面中查看網址，也可以運行heroku config --app rxlcc並查找DATABASE_URL。

注意：說明會告訴您如果打算使用Heroku，請更改.gitignore並檢查.yml文件。如果你要保密密鑰在那裏，那麼我不會這樣做，但如果你這樣做，不要使回購公開一個！如果其他人知道一個祕密，您需要需要重新生成它。

個人而言，我將通過

heroku config:add SECRET_VARIABLE=blahblahblah --app rxlcc

添加任何祕密，然後將其讀入其中，它通過

my_secret_variable = ENV["SECRET_VARIABLE"]

我看到了應用程序設置配置爲https://github.com/hayksaakian/rxlcc/blob/master/lib/firefly/server.rb#L209，並在之前的塊所需要的應用程序在https://github.com/hayksaakian/rxlcc/blob/master/lib/firefly/server.rb#L109。在任一點你可以嘗試：

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

添加任何祕密變量。

我也認爲firefly.yml中的hostname變量應該指向公有領域而不是數據庫，儘管 –

是的，firefly.yml中的'hostname'是用於公共領域的url。 'host'是database.yml應該指向數據庫服務器。在這個例子中，這被假定爲localhost，但在生產中很少會如此。如果您運行'heroku config'並獲取HEROKU_POSTGRESQL_NAVY_URL的值並將其添加爲DATABASE_URL（如果它不存在），則它也將使其更容易移植。如果DATABASE_URL不存在，我可以使用我的所有應用程序。 – iain

感謝您的幫助。在與螢火蟲開發者交談後，似乎2.0尚未準備好生產。我現在順利使用https://github.com/ariejan/firefly-heroku。 –

在Heroku上設置Firefly（ruby link shortener）2.0？
