Parsing xlsx file in ruby using gem roo

Question

My HTML code, here am passing xslx file for parsing,

<form method="post" action="/home/parse_xlsx" enctype="multipart/form-data">
   Upload XSLX File <input type="file" name="xlsx_file" id="xlsx_file"  />
   <input type="submit" value="Post"/>
</form>

My Controller code,

def parse_xlsx
    xlsxFile = params[:xlsx_file]
    prefix_tmp_path = xlsxFile.path
    filename = xlsxFile.original_filename
    fullname = File.join(prefix_tmp_path,filename) 

    require 'roo'
    s = Roo::Excelx.new(fullname)

    for i in 1..14
      puts s.cell(i,3) 
    end
end

Giving me error ,

file /tmp/RackMultipart20130910-10043-u4nqsc/CMS.xlsx does not exist

When I run the following code on console am keeping my 'CMS.xlsx' file in rails root folder & it is running without any errors.

require 'roo'
s = Roo::Excelx.new("CMS.xlsx")
for i in 1..14
  puts s.cell(i,3) 
end

Please explain where I am going wrong.

Answer 1

xlsxFile.path is the file's location, you shouldn't have to join in the filename. If you need to save the file, you can rename it the original filename when you move it to it's file location

try

 s = Roo::Excelx.new(xlsxFile.path)
