Hi,<br><br>I'm new to BackgroundRB and am having some trouble figuring<br>out what must be a simple thing. I'm in time crunch where I<br>need my Rails app to generate PDF files on the fly for my website<br>users. But before I leap into that, I'm trying to get familiar with<br>the basics. So I have this worker in my rails app lib/worker folder:<br>==============<br>class PdfmakerWorker < BackgrounDRb::MetaWorker<br> set_worker_name :pdfmaker_worker<br> set_no_auto_load(true)<br> def create(args = nil)<br> # this method is called, when worker is loaded for the first time<br> register_status(:cnt => 0)<br> 1.upto 100000000 do |x|<br> if x % 1000 == 0<br> register_status(:cnt => x)<br> end<br>
end<br> #exit<br> end<br><br> def getres<br> res = "Just a test"<br> return res<br> end<br>end<br><br>============================================================<br><br>I've written a simple program to test that worker and it is as follows:<br><br>jk = MiddleMan.new_worker(:worker => :pdfmaker_worker, :job_key => "123", :data => nil)<br><br>sleep (5)<br><br>count = 0<br><br>while count < 1 <br> pct = MiddleMan.ask_status(:worker => :pdfmaker_worker, :job_key => jk)<br> sleep(2)<br> puts "Count is: " + (pct[:cnt]).to_s<br> <br> res = MiddleMan.worker(:pdfmaker_worker, jk).getres<br> puts "Res is: " + res.to_s<br>end<br>============================================================<br><br>I run script/console and load the above program. The worker counts up<br>to 10000000 and my little test program repeatedly queries the worker<br>and writes
"Count is <whatever>" to the screen as it should.<br><br>However, when it get to my custom method "getres" in the last<br>two lines of the test program, the return result for "res" is nil. The worker doesn't crash, it just appears not to return a result. I'm sure it's<br>something simple, but I don't see why. <br><br>Here is a sample output of one iteration of the simple program:<br>================<br>Count is: 970000000<br>{:type=>:do_work, :worker=>:pdfmaker_worker, :worker_method=>:getres, :job_key=>"123"}<br>Res is: <br>{:type=>:get_status, :worker=>:pdfmaker_worker, :job_key=>"123"}<br>================<br><br>It looks like the call to "getres" is being recognized, but I'm obviously<br>missing some critical link.<br><br>My setup:<br><br>Ubuntu 7.10<br>Ruby 1.8.6<br>Rails 2.0.2<br>BackgroundRB (been through several versions, latest of <br>which was retrieved via svn on 4/17/08 and I updated the<br>backgroundrb script
as per install guidelines)<br><br>Thanks in advance for your help.<br><br>Rogelio<br><br> <p>
