Because, when I saw error at: http://pastie.caboo.se/150225 It clearly says thats start_worker is failing on 114 line. Generally this happens, when bdrb is not able to load a particular worker file. Also, you see empty string "gem_original_require': no such file to load -- (LoadError)" because bdrb is not able to get name of worker file to load correctly. > > ===== controller that instantiates worker ===== > class Admin::BatchController < Admin::ApplicationController > > def initialize > super > @formats = GW::BatchListing::ListingRow.formats > @part_of = :admin > end > > def get_progress > if request.xhr? > progress_percent = MiddleMan.get_worker(session[:job_key]).progress > render :update do |page| > page.call('progressPercent', 'progressbar', progress_percent) > page.redirect_to( :action => 'done') if progress_percent >= 100 > end > else > redirect_to :action => 'index' > end > end > > def done > errors = "DONE " + MiddleMan.get_worker(session[:job_key]).errors > if errors.size > 0 > flash[:notice] = errors.join("<br/>") > else > flash[:notice] = "Successful load." > end > MiddleMan.delete_worker(session[:job_key]) > end > > def add > @user = User.find(params[:id]) > @cats = Category.find(:all, :conditions=>"parent_id is null") > if request.post? > listings = params[:listings] > content_type = listings.content_type.chomp > if "application/zip"!=content_type and > "application/x-zip-compressed"!=content_type > flash[:notice] = > "Only files of type application/zip " + > "and application/x-zip-compressed " + > "can be used.

To get an idea about, which methods are defined for MiddleMan, have a look at, http://backgroundrb.rubyforge.org/classes/BackgrounDRb/WorkerProxy.html Also, you should read README file that comes with plugin. > ===== and the worker itself ===== > class BatchImportWorker < BackgrounDRb::MetaWorker > attr_reader :progress > attr_reader :errors > set_worker_name :batch_import_worker > > def create(args = nil) > # this method is called, when worker is loaded for the first time > end > > def do_work(parser) > @progress = 0 > @errors = parser.process(tmpfile) > end > end Well, I find no problems with above worker code, and it should load. Create a fresh rails app and see if bdrb works there. -- Let them talk of their oriental summer climes of everlasting conservatories; give me the privilege of making my own summer with my own coals. http://gnufied.org _______________________________________________ Backgroundrb-devel mailing list [email protected] http://rubyforge.org/mailman/listinfo/backgroundrb-devel
