if params[:attachment][:file].blank?
flash[:error] = "No file selected for upload"
redirect_to :action => 'new' and return
end
content = params[:attachment][:file].read
if content.blank?
flash[:error] = "Selected upload file was empty"
redirect_to :action => 'new' and return
end
# do something with content
@attachment.file = content

I just want this thread to go away and the answers you're getting are
paying attention to what you asked. Note that this code came from an
old project that was Rails 1.1.6 (yeah, *that old*) and my "do
something" was to hand off to a BackgrounDRb task to do the processing
not really put the content into the database. YMMV
