I''m writing an application where the user will be uploading many images
and user feedback is essential.
I''ve been trying to get the upload progress bar plug-in to work, but
thus far have not had any success.
I''ve downloaded Sean Treadway''s application code from his
site
http://sean.treadway.info/demo/upload/ and I followed the steps in his
Upload Progress Checklist.
I''ve tried this on both my Gentoo and WinXP boxes using the Rails 1.0.
def upload
case @request.method
when :post
@message = ''File uploaded: '' +
params[:document][:file].size.to_s
upload_progress.message = "Simulating some file processing
stage 1..."
session.update
# Dump information about uploads
@session[:uploads].each {|k,v| logger.debug("Debug:
#{k}----->#{v.completed_percent}")}
sleep(3)
upload_progress.message = "Continuing processing stage 2..."
session.update
sleep(3)
redirect_to :action => ''show''
finish_upload_status "Hello ''#{@message}''"
end
end
My problem is that no matter the file size by the time to debug
statement is reached the entire file has always been uploaded. So the
progress bar jumps from 1 to 100 with no in between steps. I can step
through with a debugger and see this session being updated with file
size, bit rate, etc. information as the file is being uploaded, but no
luck with the bar.
Should I resign myself to putting up a pretty swirly animated graphic
and telling the user "it won''t be long now" ? has anybody
had any
success with the getting the upload progress bar to work? can anybody
provide any sample application code or suggest alternatives to using the
progress bar? thanks for any help...

It seems you might be missing the upload_status. This is what I''ve
done:
***
Controller
***
class UploadController < ApplicationController
upload_status_for :upload_file, :status => :upload_status
def upload_file
if request.post?
# write the file to disk
write_file(params[:document][:file])
# redirect to the next page
redirect_to :home_url
# update the client
finish_upload_status "''#{@message}''"
end
end
def upload_status
# you can work with the various upload_progress components here...
render :inline => ''<%=
"#{upload_progress.completed_percent} %
complete" %>'', :layout => false
end
protected
def write_file(file)
f_name = sanitize_filename(file.original_filename)
File.open("#{RAILS_ROOT}/public/images/#{f_name}",
"wb") do |f|
f.write(file.read)
end # closes the file write
end
def sanitize_filename(file_name)
# get only the filename, not the whole path (from IE)
just_filename = File.basename(file_name)
# replace all none alphanumeric, underscore or perioids with
underscore
just_filename.sub(/[^\w\.\-]/,''_'')
end
end
***
View
***
<div id=''upload_form''>
<%= form_tag_with_upload_progress :action =>
''upload_file'' %>
<%= file_field "document", "file" %>
<%= submit_tag "Upload" %>
<%= upload_status_text_tag %>
<%= end_form_tag %>
</div>
***
HTH.

I also might depend on the weberserver you are using, I remember with older versions of lighttpd getting the same of what you described (but I don''t know about newer lightpd versions) On 1/6/06, Joshua Paul <joshpaul@mac.com> wrote:> > It seems you might be missing the upload_status.

Hi, I too have Rails 1.0 running under apache. But I am getting error message for form_tag_with_upload_progress, it seems it''s not identifying this tag. The same happens in Rails 1.1. It would be very kind of you if you can tell me something in this regard. cheers..

Daniel, I tried to get this working for a couple of days on Rails 1.0 and ended up at the exact same place. What I think that I observed was that the Ajax calls to do the updating would not start until the file upload was complete, then the intermediate status polling would begin. So it would go from 0% to 100% and then I would see the Ajax periodical updater calls happen. Unfortunately, I finally gave up. I did not get to debugging within the upload code - I did my debugging on the client side, but my results are consistent with yours. Because this was my very first experience with Ajax and Prototype I thought it best to get some other Ajax stuff working first before I came back to it. If you want to try and work through it together, perhaps we could do that. FWIW, you''re not alone ;). Thanks, Wes (Aside, As I said this was on Rails 1.0 - looks like all of these components moved or disappeared for 1.1 - if you have any insight into where they are in the 1.1 distribution, please advise...)
