Can't host file upload sample app on heroku

Rails
1

Hi,
After hosting my sample app for file upload on heroku using the FREE
account, it does not work properly. However, everything works fine on
my local machine. Please help

FOR FILE UPLOAD::
// controller.rb
def uploadFile
if params[:upload] == nil
redirect_to(:action => :home, :notice => “File field must not
be empty”)
else
name = params[:upload].original_filename
directory = “keePass/public/data”
path = File.join(directory, name)
File.open(path, “wb”) { |f|
f.write(params[:upload].read) }
redirect_to(:action => :arrive, :notice => “File has been
uploaded successfully”)
end

end

// view.html.erb

File Upload

<% form_tag ({:action =>‘uploadFile’}, :multipart=>true) do %>

Select File :
<%= submit_tag "Upload" %> <% end %>

TWO::: FOR DELETING OF UPLOADED FILE(S)
//controller.rb
def cleanup
file = params[:file]
@numFiles = 0
dir = Dir.entries(‘keePass/public/data/’)
dirN = Array.new
dir.each{|x|
if File.exist?(x) == false
dirN << x
end
}
if dirN ==[]
redirect_to(:action =>:arrive, :notice =>
‘There are no files in this folder!’)
else
dirN.each{|c|
File.delete(File.join(‘keePass/
public/data/’,c))
@numFiles +=1
}
redirect_to(:action =>:arrive, :notice =>
" #{@numFiles} File(s) deleted!")
end
end

// view.html.erb
<%=link_to ‘Delete All Files’, :action => :cleanup%>

Heroku does not support file uploads. The filesystem is readonly. You’ll
have to host your files somewhere else.

S3 is a common choice: http://devcenter.heroku.com/articles/s3

Maybe you have reasons why not, but if you use the Paperclip gem, it has
easy integration with S3.
