excel - Rails send file xlsx didn't work -


i use axlsx generate excel, confused how let user download it.

i wrote in download controller, , excel file's path public/excel/timestamp.xlsx.

def code_generator   if request.post?     #generate xlsx......     excel_path = "#{rails.root}/public/excel/" + datetime.now.strftime('%q') + '.xlsx'     send_file excel_path, :disposition => "attachment"   end end

when post data controller, browser didn't create download action.

however, in terminal, displayed

2016-11-08 17:01:56.971 [info] sent file /users/username/desktop/project_name/public/excel/1478595716963.xlsx (0.1ms)

update

i found out there's nothing send_file.

here original code 

# code_generator.html.erb <%= form_tag('/admin/code_generator', method: 'post', remote: true) %>

i change 

<%= form_tag('/admin/code_download') %>

add new controller method code_download, same thing original code_generator.

but time, works. i'm not sure, guess problem causes remote: true?
