部署Publify博客Heroku導致應用程序錯誤

我試圖部署一個新的安裝Publify博客Heroku。一切工作正常我的本地計算機上。部署Publify博客Heroku導致應用程序錯誤

而且git push heroku master不說有關問題的任何東西：

但在那之後我看到這個應用頁面：

應用程序錯誤
應用程序中發生錯誤，您的頁面可能不被服務。請稍後重試。

如果您是應用程序所有者，請查看您的日誌以瞭解詳細信息。

和Heroku的日誌顯示此：

我做錯了什麼？我想我需要在部署到Heroku之前設置它。

database.yml文件是：

login: &login 
    adapter: postgresql 
    host: localhost 
    username: ***** 
    password: ***** 

development: 
    database: typo_dev 
    <<: *login 

test: 
    database: typo_tests 
    <<: *login 

production: 
    database: typo 
    <<: *login

Heroku的運行耙分貝：遷移輸出是：

你配置了你的數據庫嗎？如果是這樣，你可以發佈你的配置嗎？您運行的是 –

：heroku rake db：migrate？ –

請注意，在Heroku中，您的'database.url'被替換 - '寫入config/database.yml以從DATABASE_URL中讀取。請參閱[Ruby buildpack]（https://github.com/heroku/heroku-buildpack-ruby/blob/v42/lib/language_pack/ruby.rb#L441-504）。 – matt

當Rails的加載database.yml文件，它實際上filters it through ERB before loading it as a Yaml file。這樣可以使用Ruby動態創建配置，例如將密碼保存在存儲庫中。

當您將Rails應用程序推送到Heroku時，a new database.yml file is created, replacing the original。這個新的database.yml使用ERB從DATABASE_URL環境變量構建配置，所以實際上它不是一個「純粹的」Yaml文件 - 你可以認爲它是類似database.yml.erb的東西。

錯字的Gemfile loads the database.yml file然後parses it as Yaml，但不是通過ERB先餵它。您看到的錯誤是由Yaml解析器讀取文件引起的，但由於它是ERB而無法正常工作，所以Yaml無效。

要修復它，您需要確保database.yml文件在被讀爲Yaml之前通過ERB。在您的Gemfile更改的行

conf = YAML.load(File.read(dbfile))

到

require 'erb' 
conf = YAML.load(ERB.new(File.read(dbfile)).result)

你可能想打開的bug報告錯字，甚至發送pull請求。

有一個錯字：不是Rakefile，而是Gemfile。除此之外，這爲我工作。謝謝。 –

@JanWrobel謝謝！固定。 – matt
