Looks like my first question a couple of days ago wasn?t very clever
asked, at least very sucessfull....
So, anyway...i will try it again:
I have to prefix that I am far away from fully understanding the overall
concept yet, and there?s no way to get some hints in the www so far, at
least my resaerches dont lead to any helpfull stuff.
image_controller.rb:
def create
MiddleMan.new_worker :class => :image_worker,
:job_key => :upload_img,
:args => { :image => params[:image]}
worker = ::MiddleMan.worker(:upload_img)
end
image_worker.rb
require ''RMagick''
class ImageWorker < BackgrounDRb::Worker::RailsBase
##attr_accessor :text
def do_work(args)
##@text = args[:text]
@image = Image.new(args[:image])
@image.dimensions
@image.save
end
def progress
results[:progress]
end
end
ImageWorker.register
image.rb
require ''RMagick''
class Image < ActiveRecord::Base
belongs_to :user
validates_filesize_of :image, :in => 15.kilobytes..1.megabyte
validates_file_format_of :image, :in => ["gif", "png",
"jpg"]
file_column :image, :magick => {:versions => {"thumb" =>
"150x100",
"picture" => "600x450>"}}
def dimensions
img = Magick::Image.read(self.image).first
if img.columns >= img.rows
ratio = img.columns.to_f / 600
else
ratio = img.rows.to_f / 450
end
self.width = ((img.columns / ratio)+10).to_i
self.height = ((img.rows / ratio)+10).to_i
end
end
So, this isn?t working...in fact I would be surprised if it would be
that easy, as I just shifet code away from the controller to the worker...
Ok:
when submitting the uploadform at least the worker get fired and passed
the args as expected, as I can see in the backgroundrb_server.log:
20070201-10:47:29 (53830) Starting worker: image_worker upload_img
(image_worker_upload_img)
(imagecreated_on(2i)2created_on(3i)1created_on(4i)00created_on(5i)18updated_on(1i)2007updated_on(2i)2image_tempdescriptionbackgrounDRb33updated_on(3i)1imgnum007updated_on(4i)00image#<File:0x8d13028>updated_on(5i)18created_on(1i)2007)
Now there are 2 questions:
the image isnt uploaded, that is probably due to the fact that the
file_columnPlugin isnt available for the backgrounDRbserver..
My research turned out, that for the earlier version of the backgrounDRb
you had to insert
//require File.dirname(__FILE__) + "/../../config/environment.rb"
//
in the scrip/backgroundrb/start script..there is no such script in the
actuall version and i cant see where to put that now.
So, anyway, also if the image isnt uploaded physically shouldnt i expect
at least an DB entry for the passed args as I call the save method on
@image ??
Further I think the dimension method should go also in the worker, but
step by step, and I am still totaly lost, so I just ask you kindly again
to provide some input to enlighten me and others, as I guess that a lot
of ppl are still missing some real world examples except of some
cronlike or outdated stuff
best regards

Hey there- I think you have a misconception of what backgroundrb can be used for. There is no way to use backgroundrb to do a progress bar for a file upload. Because the entire image will have to be uploaded before rails will pass it to backgroundrb. Looking at your code I think you are better off not using backgroundrb and just doing what you are doing all in rails. Is that your goal? TO have a progress bar for file uploads? If so you are barking up the wrong tree sorry. You can look at the mongrel_upload_progress gem to see about progress bars for file uploads.

Hi Ezra, thank you very much for your reply as it saves me another few hours if not stays just get back my old working code ... and don?t try further. First of I was coming around your plugin for cornjobstuff and it works great, so one time installed and reading through the www about it I came also across various blogentries about it, and one mentioned that backgrounDRb is for much more than jst cronjobs as imageprocessing, massmailing ..and conclued: for everything what takes a bit longer So maybe i was misinterpreting this, my fault The progressbar wasnt the reason i tried with backgrounDRb, it was just a wild guess that it would be somewhat faster that way But, you are right, progressbars are like the state of the art today for imageuploading, so I am better of from backgrounDRb for that and spending my time in the mongrel_upload_progress gem for such feature Once again, thanks for the reply and the great plugin matthias Ezra Zygmuntowicz schrieb:> Hey there- > > I think you have a misconception of what backgroundrb can be used > for.
