如何在導軌中播種照片

Question

我正在使用回形針，但不知道如何播種。

我有一個佔位符，在我的本地路徑（OSX）爲/Users/me/dev/APP/doc/seeding/300x220.jpg

我的種子文件是：

p = Photo.new({:description => 'one', :created_at => "Sun, 1 Jan 2012 01:01:01 -0500".to_datetime, :updated_at => "Sun, 1 Jan 2012 01:01:01 -0500".to_datetime }) 
p.image_file_name = File.open(Rails.root.join('doc', 'seeding', '300x220.jpg')) 
p.save! 

我的錯誤返回：

Searching the rdoc for paperclip，沒有返回。

其他文件，可能會有所幫助：

架構的照片：

create_table "photos", :force => true do |t| 
t.string "description" 
t.datetime "created_at",   :null => false 
t.datetime "updated_at",   :null => false 
t.string "image_file_name" 
t.string "image_content_type" 
t.integer "image_file_size" 
t.datetime "image_updated_at" 
end

photo.image = File.open(file_path) 
photo.save!
