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
<h1>File Upload</h1>
<% form_tag ({:action =>''uploadFile''},
:multipart=>true) do %>
<p><label for="upload_file">Select 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%>

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 -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
