image upload problem. Uploaded file size 0 bytes

Question

I am trying to upload an Image.

The image file gets created but the size of the file is 0 bytes.

Here is the code in controller

name =  params[:comparison][:image1].original_filename
name_content_type = params[:comparison][:image1].content_type
directory = "public/images"
path = File.join(directory, name)
file = File.open(path, "wb") { |f|
         content = params[:comparison][:image1].read
         f.write(content)
       }
# also tried the below but doesn't work
# file = File.new(path, "wb") { |f| f.write(params[:comparison][:image1].read) }
# RAILS_DEFAULT_LOGGER.info(file) is showing 0

Can anyone point me to working demo with code? I know this is such a simple stuff! not sure why its not working...!!!!

Answer 1

Are you using <form enctype="multipart/form-data"... ?
