如何使用simple_form在rails 4中获取此文件（回形针）对象的文件属性？

Question

Im uploading a file into my rails 4 app using paperclip and simple_form with the following code.

What Id like to do in the following code is substitute the word "file" for the actual file name and extension in the dailogue box. Id also like to customize the message in the dialogue box. I wonder how to accomplish that.

views/uploads/_form.html.erb

 <%= simple_form_for task.uploads.build, :html=> {:multipart => true} do |f| %>
     <%= f.hidden_field :task_id, :value => task.id %>

     <%= f.error_notification %>
     <%= f.file_field :sourcedata %>
     <%= f.button :submit, "Upload this file \nto server" ,:confirm => "Upload File",:class=> "upload_tasks_button"%>

 <% end %>

I appreciate any suggestions to customize the dialogue box.

Thanks
