getting images from array

Hi

I have this kind of code source for uplaodin an image.
from controller:
def uploadFile
    @text = "File has been uploaded successfully"

    post = DataFile.save(params[:upload])
    render :text => @text

end

from model:
def self.save(upload)
    name = upload['datafile'].original_filename
    directory = "public/data"
    #Creating the file path
    path = File.join(directory, name)
    #write the file
    File.open(path,"wb"){ |f| f.write(upload['datafile'].read) }
end

But variable upload should be sent on array in new version. If i wan't
to go through that array what is the easist way.
Do i have to do just loop. I am newbie on rails so i am lit bit
confused about the dynamic variables.

http://clarkware.com/cgi/blosxom/2007/02/24, this might help.

and yes, if you want to accept an array instead of a variable, then
you would need to loop through it so that you can save many images;

== controller

def upload_file # please don't camel case
   images = params[:images]
   #do your stuff
   Model.save images
end

=== model

def self.save images
  images.each do |image|
    # save files
  end
end

But i strongly suggest you do it the rails way, as the files will be
much easier to manage.

Thanks for replay. I have to tried it by rails way.
