similar to: accessing controller methods from backgreoundrb

Hi, I''ve started to implement page caches but I''ve hit a brick wall getting a sweeper to clear the cache when needed. It seems that any models that I tell it to observe aren''t being observed properly. If I add the sweeper to a controller the initialize method runs, but no matter what I do the after_save/after_update callbacks aren''t running. Also if I try to

Hi, it probably is a noob question but I''m confused by this error message: active_support/dependencies.rb:478:in `const_missing'': uninitialized constant Invoice::ApplicationController Situation: I have an InvoicesController with a create method that in turn calls upon a MiddleMan.worker(:billing_worker), which in turn finds an Invoice and calls upon @invoice.print_invoice

Hi, I am trying to generate a PDF from within a worker using PDF::Writer. In my controller I use render_to_string to create the pdf file however from what I understand render_to_string can only be used from a controller. Does anybody have any suggestions how I might be able to replicate this functionality in a worker? -- thanks, Felix -------------- next part -------------- An HTML attachment

Hi, I''m trying to use sweepers for the first time and got a problem - I get "undefined method `merge'' for "/signature/ f2d7c7c66450b169.html":String". The "/signature/f2d7c7c66450b169.html" part of the error message is the cached page. Here''s my sweeper: class FooSweeper < ActionController::Caching::Sweeper observe Foo def

Sorry if this comes through twice. I already sent this once, before joining the mailing list. I''m attempting to use Backgroundrb to handle asynchronous pdf creation, but in doing so, I''ve run into a very strange problem. Below is a method that''s called from the controller which creates a new worker, then grabs the worker and calls the ''build_pdf''

Is it possible to call render_to_string from with in a brb worker? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://rubyforge.org/pipermail/backgroundrb-devel/attachments/20070611/21c1821a/attachment.html

Hi all, I''m using the older win32 happy backgroundrb in combination with the ''acts_as_ferret'' install as a plugin. Since I''ve installed acts_as_ferret, I haven''t been able to get backgroundrb to start. It keeps failing at the ''acts_as_ferret'' method call in one of my models. Here''s a code snippet of the model: class Book

Hi, I have a long running task which generates JavaScript to files and I am hoping to move this to a backgroundrb worker. The javascript is currently generated with call to render_to_string: File.open(File.join(target_folder, ''all.js''), "w") do |file| file.puts(render_to_string :partial => ''partials/shared/javascript/tags'', :locals => {

I created a script that I call by ''./script/runner -e production UpdateItems.get_new_items()'', which basically calls the model Item: Item.create(attributes...) I''ve set up a cache sweeper which removes caches after each create/destroy/update on Item, and it works fine when accessing controllers via the web server, but apparently doesn''t work via runner.

I''m using a cache sweeper class [1] to take care of some pretty complex sweeping. However, there is a problem with the current implementation. Namely, the sweeper gets called only when an action named in cache_sweeper is called using GET. As many methods where sweeper would be useful are using postback to send the form to the same action, this causes the cache to get swept when

I''m working on an app that''s basically forms and that makes fairly heavy use of Ajax. As a result of the Ajax usage, if the visitor uses the back button they get the page as it was originally loaded, not as they left it. I''ve looked at the Sweeper documentation and can not tell for sure that it''ll do what I want, which is to force an unconditional reload from

Hi everyone, I am trying to extend an active record model using obj.extend(module). The aim is to overwrite some of the model methods depending on what''s in the object. For example, the base class would be "file", with objects such as "image", and "text". The aim is to be able to something like this: file = File.new() file.extend(Image) file.process

Hi, I''ve been playing with backgroundrb to batch process a bunch of images on a rails server. The process is working fine when backgroundrb is started from the command line, but seems to choke occasionally (well, quite often) when running as a service. It seems to get stuck on the following line when moving files: FileUtils.move(src, dest, :verbose => true) with the error: Bad

Hello, I''m running Mongrel 0.3.13.3, cluster 0.2.0, and Rails 1.1.6 and I have a problem with a sweeper not having access to the controller instance.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, i''m trying desperately to schedule some worker methods within rails 2.0.2.

I noticed a lot of repetition across different Sweeper models in my app expiring the same fragments and so have been trying to move all the expire_fragment calls into another model which the sweepers can then use but it''s not working as I''d hoped.. I''ve created a CacheDestroyer model and want to be able to call something to the effect of:

First let me say that Rails caching is very very cool. The traffic (and responsiveness) I''ve saved by added 10 lines of ruby code would be enourmous, if I actually had traffic... ;) Sweepers as observers are great, btw. Since every page of my side is dynamic, once I did some DB optimization I''m caching the content of the index page which was taking the bulk of the time to load

Hi, I''m a long time backgroundrb user, still stuck using the very ancient original version from Ezra (not even Ezra''s 2.0 version, I''m using the one that didn''t really have a version number). The 2.0 version did very little but crash for me. Anyway I finally got some time set aside to try out this new version you all have been developing.
