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](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.
