Hi,
I've been trying to use the mongrel_upload_progress gem to implement a file upload progress indicator. The progress bar doesn't work properly: it starts at 0% and it jumps to 100%.
I realized this is because the progress() function in the controller (http://mongrel.rubyforge.org/attachment/wiki/UploadProgress/files_controller.rb) does get periodically called, but the @status object is nil. I think the @status object contains the current upload data. That is because nobody is calling the Mongrel::Uploads.add(upid, size) function at the start of the download. It is this function which initializes @status. I added that as a new AJAX call, however, I don't know where to get the size from (so I hard-coded it for now). Even like this, it doesn't work 100% well. Now I do see a new line that says "X bytes of XMB uploaded", but the progress bar is still not being incremented. You might say that the upload is too fast: not true; I tried different sizes with different connections.
My question is: did anyone manage to get this mongrel_upload_progress to work successfully? What kind of modifications to the sample files did you make? Is this really used in production by anyone?
Thanks, Tiberiu
