耙分貝：種子抱怨的形式沒有被多編碼

Question

我有一個seeds.rb文件：

activity1 = Activity.create! :name => 'Football', :icon => File.read("#{Rails.root}/public/images/activity_icons/football.png") 

但是當我運行耙分貝：種子，過程失敗，我得到一個錯誤信息：

You tried to assign a String or a Pathname to an uploader, for security reasons, this is not allowed. 

If this is a file upload, please check that your upload form is multipart encoded. 

好，手工圖標上傳做的工作，因爲我的形式是多編碼，所以我猜測，耙正在使用它自己的運行形式seeds.rb。

我該做些什麼來完成這項工作？除了每次手動添加圖標我重新我的分貝

設法解決這得益於following question

就不得不修覆在我的種子代碼文件位。以下作品：

activity = Activity.create! :name => 'Football', :icon => File.open(File.join(Rails.root, '/public/images/activity_icons/soccer.png'))
