未定義的方法`異步=」對的ActionMailer :: Base的：類中軌4

Question

我嘗試使用新的軌道基於鋼軌4異步郵件指導here

在我的config/application.rb中我加

config.action_mailer.async = true 

，並在我的ActionMailer我加

class welcomeMailer < ActionMailer::Base 
    #self.async = true 
end 

這些結果undefined method async= for ActionMailer::Base:Class當我嘗試運行我的rails server。我試圖耙我的工人，但耙子也將因此而失敗。

謝謝你的幫助。

進一步更新：

顯然，他們拉了排隊功能，以及：

移至後臺作業的「工作」分支，直到完全成熟。沒有與Rails 4.0一起發貨。

'async'的唯一提及在active_record，action_view/actionpack或指南下。

./guides/source/form_helpers.md:Unlike other forms making an asynchronous file upload form is not as simple as providing `form_for` with `remote: true`. With an Ajax form the serialization is done by JavaScript running inside the browser and since JavaScript cannot read files from your hard drive the file cannot be uploaded. The most common workaround is to use an invisible iframe that serves as the target for the form submission.
