Upload progress update bar question

Rails
1

I’m trying to follow these instructions to include the Javascript
progress bar on a page. However, I’m confused.

In my controller, when I try to access

update_upload_progress_bar_js

which is defined in

actionpack/lib/action_view/helpers/upload_progress_helper.rb

I get a “no such method” error.

Can I use helpers in my controller class and, if so, how do I access
them?

Thanks,
Wes

=========================================================

upload_progress_update_bar_js(percent=nil)

Javascript helper that will create a script that will change the width
of the background progress bar container. Include this in the script
portion of your view rendered by your upload_status action to
automatically find and update the progress bar.

Example (in controller):

def upload_status
render :inline => “”, :layout => false
end

OK I just realized a fundamental misunderstanding that I had - that the
controller was invoking the helper, which of course it isn’t.

So now I just have to figure out why the helper class can’t be found.

There’s an error in the documentation - the method name is

upload_progress_update_bar_js

How do I report a doc. error like this?
