Attachment_fu插件是慈祥的老人，但我必須修改舊的應用程序，我不能使用其他插件像回形針等，因此，這裏是事不宜遲代碼Attachment_fu文件保存問題
Submissions table structure
---------------------------
| content_type | varchar(255) | YES | | NULL
| filename | varchar(255) | YES | | NULL
app/models/submission.rb
------------------------
has_attachment :storage => :file_system,
:path_prefix => 'public/submissions',
:max_size => 2.megabytes,
:content_type => ['application/pdf', 'application/msword', 'text/plain']
app/models/user.rb
------------------
has_one :submission, :dependent => :destroy
app/views/user/some_action.html.erb
-----------------------------------
<% form_for :user, :url => { :action => "some_action" }, :html => {:multipart => true} do |f| %>
....
<%= file_field_tag "submission[uploaded_data]" %>
<%end%>
app/controllers/user_controller.rb
----------------------------------
@user = User.find_user(session[:user_id])
@submission = @user.submission
if request.post?
@submission.uploaded_data = params[:submission][:uploaded_data]
end
當表單提交後，數據庫字段「content_type」和「filename」得到更新並顯示正確的值，但該文件未出現在public/submissions/目錄中。我已檢查提交目錄上的權限。
我錯過了什麼？
非常感謝
