CAN'T HOST FILE UPLOAD SAMPLE APP ON HEROKU

2011-05-05 Thread ken bob 
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
h1File Upload/h1

% form_tag ({:action ='uploadFile'}, :multipart=true) do %
plabel for=upload_fileSelect File/label :
input type=file name=upload /br/
%= 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%

Re: CAN'T HOST FILE UPLOAD SAMPLE APP ON HEROKU

2011-05-05 Thread Ben Scofield 
Heroku applications run in a read-only filesystem -- you can't upload
files directly. Instead, you should be uploading them to an external
service like S3. Here's the relevant Dev Center article on the
limitation: http://devcenter.heroku.com/articles/read-only-filesystem
