Salesforce REST API：Databasedotcom gem上傳附件

我正在使用Heroku的Databasedotcom gem在我的Ruby on Rails應用程序中與Salesforce的REST API進行交互。我可以通過API成功創建帳戶，但是我無法添加附件。我發現這個建議https://github.com/heroku/databasedotcom/issues/98，也做了以下內容：Salesforce REST API：Databasedotcom gem上傳附件

# Upload to Salesforce attachment 
salesforce_attachment = Salesforce.client.materialize("Attachment").new 
salesforce_attachment.Body = Base64::encode64(File.read(temp_file_path)) # critical line 
salesforce_attachment.OwnerId = Salesforce::Sobjects::OWNER_IDS[:OWNER_ID] 
salesforce_attachment.ParentId = Salesforce.find_or_create_account_for_user(user) 
salesforce_attachment.Name = file_name 
salesforce_attachment.IsPrivate = false 
salesforce_attachment.save # this isn't saving for some reason

當我試圖挽救，但我得到以下錯誤：

Databasedotcom::SalesForceError: Cannot deserialize instance of reference from START_OBJECT value { at [line:1, column:2] 
from /Users/oregontrail256/.rvm/gems/ruby-1.9.3-p545/gems/databasedotcom-1.3.2/lib/databasedotcom/client.rb:376:in `ensure_expected_response'

from script/rails:6:in `<main>'

我已經嘗試了不同的文件，並仍然得到問題。我強烈懷疑這與設置附件的「Body」屬性有關，但我無法弄清楚我做錯了什麼，因爲包括Salesforces' developer docs在內的所有資源都會對base64進行編碼。而且我不超過他們的5Mb限制。有什麼建議麼？？？

好吧我想通了：當我設置附件的ParentId時，我使用的是實際的Account對象，而不是Account對象的ID。即：

# wrong 
salesforce_attachment.ParentId = Salesforce.find_or_create_account_for_user(user) 

# right 
salesforce_attachment.ParentId = Salesforce.find_or_create_account_for_user(user).Id
