被調用的ID爲零

Question

我想在我的OS X機器上安裝Shapado。最終我想在Heroku上安裝它，所以如果有人有安裝指南，請讓我知道。

我相信所有的依賴都行，mongodb正在運行。我得到一個錯誤，當我運行：

$rake bootstrap RAILS_ENV=development

Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id 
/Users/sean/Dropbox/rails/shapado/app/models/group.rb:641:in `set_shapado_version' 

問題的代碼是這樣的：

def set_shapado_version 
    self.shapado_version_id = ShapadoVersion.where(:token => 'free').first.id 
end 

Answer 1

在app /型號

/group.rb改變

def set_shapado_version 
    self.shapado_version_id = ShapadoVersion.where(:token => 'free').first.id 
end 

到

def set_shapado_version 
    self.shapado_version_id = ShapadoVersion.where(:token => 'free').first.try(:id) 
end 

下面是相關的合併請求：https://gitorious.org/shapado/shapado/merge_requests/18

Answer 2

def set_shapado_version 
    self.shapado_version_id = ShapadoVersion.where(:token => 'free').first.id 
end 

你確定有一個ShapadoVersion的token ='free'嗎？我認爲Rails正在抱怨這個問題。

Answer 3

使用這個帖子：http://shapado.com/questions/rake-bootstrap-error-called-id-for-nil 我設法得到它過去耙引導通過執行以下操作：

改了行13 shapado.yml到真正

is_shapadocom: true 

添加config/payments.yml

secret: vtUQeOtUnYr7PGCLQ96Ul4zqpDUO4sOE 

添加了以下代碼破解。原始行被評論。可能不是最好的方法。

def self.reload! 
    #return unless AppConfig.is_shapadocom 
    unless AppConfig.is_shapadocom 
    ShapadoVersion.new(token: "free", price: 0).save! 
    return 
    end 
    . 
    . 
    . 

如果有人知道Shapado，請查找我的個人資料並與我聯繫。我有興趣分享經驗，特別是推動Heroku。它看起來像一個很好的應用程序，但我找不到很多文檔。
