Salesforce REST API: Databasedotcom gem to upload attachments
我正在使用 Heroku 的 Databasedotcom gem 在我的 Ruby on Rails 应用程序中与 Salesforce 的 REST API 进行交互。我可以通过 API 成功创建帐户，但我无法添加附件。我发现了这个建议 https://github.com/heroku/databasedotcom/issues/98 并做了以下事情：
1 2 3 4 5 6 7 8 | # 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，我收到以下错误：
1 2 3 4 5 6 7 8 9 10 11 12 | 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 /Users/oregontrail256/.rvm/gems/ruby-1.9.3-p545/gems/databasedotcom-1.3.2/lib/databasedotcom/client.rb:334:in `with_encoded_path_and_checked_response' from /Users/oregontrail256/.rvm/gems/ruby-1.9.3-p545/gems/databasedotcom-1.3.2/lib/databasedotcom/client.rb:307:in `http_post' from /Users/oregontrail256/.rvm/gems/ruby-1.9.3-p545/gems/databasedotcom-1.3.2/lib/databasedotcom/client.rb:234:in `create' from /Users/oregontrail256/.rvm/gems/ruby-1.9.3-p545/gems/databasedotcom-1.3.2/lib/databasedotcom/sobject/sobject.rb:115:in `save' from (irb):100 from /Users/oregontrail256/.rvm/gems/ruby-1.9.3-p545/gems/railties-3.2.17/lib/rails/commands/console.rb:47:in `start' from /Users/oregontrail256/.rvm/gems/ruby-1.9.3-p545/gems/railties-3.2.17/lib/rails/commands/console.rb:8:in `start' from /Users/oregontrail256/.rvm/gems/ruby-1.9.3-p545/gems/railties-3.2.17/lib/rails/commands.rb:41:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main>' |
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，但我不知道我做错了什么，因为所有资源，包括 Salesforce 的开发人员文档，都说对文件进行 base64 编码。此外，我没有超过他们的 5 Mb 限制。有什么建议吗？？？
好的，我想通了：当我设置附件的 ParentId 时，我使用的是实际的 Account 对象，而不是 Account 对象的 ID。即：
1 2 3 4 5 | # 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 |
