我在我的 Ruby on Rails 应用程序中使用 Heroku 的 Databasedotcom gem 与 Salesforce 的 REST API 进行交互。我可以通过 API 成功创建帐户，但添加附件时遇到问题。我找到了这个建议 https://github.com/heroku/databasedotcom/issues/98并做了以下事情:
# 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
但是，当我尝试保存时，出现以下错误:
Databasedotcom::SalesForceError: Cannot deserialize instance of reference from START_OBJECT value { at [line:1, column:2]

我尝试了不同的文件，但仍然遇到问题。我强烈怀疑这与设置附件的“正文”属性有关，但我无法弄清楚我做错了什么，因为所有资源，包括 Salesforces' developer docs ，说要 base64 编码文件。此外，我没有超过他们的 5 Mb 限制。有什么建议吗？？？
最佳答案
好的，我明白了:当我设置附件的 ParentId 时，我使用的是实际的帐户对象，而不是帐户对象的 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
