Paperclip :: AdapterRegistry :: NoHandlerError使用krajee引導文件輸入時

我使用krajee引導文件輸入在Rails中上傳多個文件。我點擊上傳按鈕後，得到了這個Paperclip :: AdapterRegistry :: NoHandlerError。任何人都可以幫助我。由於Paperclip :: AdapterRegistry :: NoHandlerError使用krajee引導文件輸入時

class WorkFile < ActiveRecord::Base 
    has_attached_file :attachment, 
    :styles => { :small => "150x150#"}, 
    :url => "/assets/work_files/:id/:style/:basename.:extension", 
    :path => ":rails_root/app/assets/images/work_files/:id/:style/:basename.:extension" 

    validates_attachment_content_type :attachment, :content_type => ["image/jpg", "image/jpeg", "image/png", "image/gif"] 
    validates_attachment_size :attachment, :less_than => 1.megabytes 
end

class WorkFilesController < ApplicationController 

def upload 
    @wf = WorkFile.new 
    @wf.attachment = params[:pm_file_upload] 
    @wf.save 
end 

end

在你的表格，你將它作爲一個多部分的形式？ – lifeiscontent

變化@wf.attachment = params[:pm_file_upload] 到@wf.attachment = params[:pm_file_upload][0]
