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%
