Question

我正在使用krajee bootstrap文件输入来在Rails中上传多个文件。点击上传按钮后，我得到了Paperclip :: AdapterRegistry :: NoHandlerError。任何人都可以帮助我。感谢

class WorkFilesController < ApplicationController

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

end

Started POST "/work_files/upload" for 192.168.0.5 at 2016-02-02 21:51:17 +0000

 SELECT CAST(Count(1) as VARCHAR(30)) AS SourceRowCount 
 FROM table 
 where countryid= '" +@[User::Id] +"'"+ " "+"
 AND locationid ="'+@[User::ID1]+'"

Answer 1

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

Paperclip :: AdapterRegistry :: NoHandlerError使用krajee bootstrap文件输入时
