Rails 3 - 嘗試創建/遷移空白數據庫名稱的Beta環境

我的應用程序適用於開發，我試圖將它部署到新的片。這個環境被稱爲'測試版'。一切似乎都工作正常，除了耙子試圖傳遞一個空白的數據庫名稱，無論是在capistrano中調用還是手動調用。我真的很感激任何幫助，因爲我不知道接下來要做什麼。谷歌搜索這沒有任何結果。Rails 3 - 嘗試創建/遷移空白數據庫名稱的Beta環境

我已經嘗試了明顯的東西像按摩我的database.yml和beta.rb文件，但沒有成功。 Mysql正常工作並創建了正確的用戶。

我剛剛切換到紅寶石1.9並發現相同的錯誤。我認爲這是來自YAML解析器的錯誤。擴展引用時似乎無法包含其他鍵。

考慮以下文件：test.yml

common: &default 
    user_name: 'test_user' 

failed: 
    <<: *default 
    database: 'ignored db name' 

success: 
    user_name: 'test_user' 
    database: 'db name'

現在看看你的紅寶石及時得到什麼：

puts YAML.load_file('test.yml').inspect 

{"common"=>{"user_name"=>"test_user"}, "failed"=>{"user_name"=>"test_user"}, 
"success"=>{"user_name"=>"test_user", "database"=>"db name"}}

爲了解決這個問題，確保的boot.rb選擇 'SYCK' ，我相信，已經有一段時間了。

require 'rubygems' 

# Set up gems listed in the Gemfile. 
ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__) 

require 'yaml' 
YAML::ENGINE.yamler= 'syck' 

require 'bundler/setup' if File.exists?(ENV['BUNDLE_GEMFILE'])
