Hello,

I try to prepare a upload page and here’s my controller:

def new  
if request.post?  
begin  
@file = params[:img]  
if @file.original\_filename.length \> 0  
filename = “/images/userimg/” + @file.original\_filename  
File.open(filename, “wb”) { |f| f.write(@file.read) }  
end  
end  
end  
end

I want the file to be saved into the public/images/userimg folder. but i  
get error at runtime: “No such file or directory -  
/images/userimg/arrowd.gif”

what can i do for it?

You check if you have folder /images/userimg 🙂

I have it: “public/images/userimg”

Do I need to get the real path of that folder?

Try:  
filename = “#{RAILS\_ROOT}/public/images/userimg/” +  
@file.original\_filename

Be aware that this could be abused. It might be possible for someone  
to put …/ in the filename and do something malicious like add a  
controller to your application or overwrite your log files.
