Details about paperclip error: ‘Paperclip::AdapterRegistry::NoHandlerError’ when you use paperclip gem in Rails

When I was working with rails and paperclip I got this error. 

Paperclip::AdapterRegistry::NoHandlerError

 = form_tag my_path, :method => :post do
  -------
  = file_field_tag "attachment" 
  -----

I submitted a form and it was not saving. There I found that the form sending a file too. I missed 

:multipart => true

option in the ‘form_tag’ when submitting the form. The form really not sening a file and paperclip not getting an attachment. So it throws this error. 

 = form_tag my_path, :method => :post, :multipart => true do
  -------
  = file_field_tag "attachment"
