similar to: Question about how Mongrel process works with singletons

Hi, it would be nice to be able to specify workers as singletons. By this I mean that every call to the new_worker method returns the same instance of said worker. This can be done transparently either by adding a new argument to new_worker (something like :singleton => true) or adding a new method, like I did in my installation of BackgrounDrb: def get_worker_by_class(klass)

I have an app that requires me to define a class variable (actually an array) in a controller and then access it from within a view. It seems that the class variables aren''t working right. Here is an example of what I''m trying to do. class DisplayController < ApplicationController @@thumbnail_array = Array.new ... def some_method @@thumbnail_array = SomeModel.find_all

I''m a bit confused about how to get upload progress to work with mongrel.. I''ve installed the mongrel_upload_progress (0.1) gem, but have no idea what to do with it. According to the following page: http://technoweenie.backpackit.com/pub/602283 there''s a patch (mup.diff) which seems like it patches the mongrel_upload_progress plugin The following blog entry makes it

How can I safely mock a singleton without the mocked method living on outside the scope of the test method? I''ve run into this problem with mocking methods on globals (gasp!) in the past by doing something like def mock_my_global original = $my_global $my_global.expects(:foo).returns(''bar'') yield $my_global = original end Is there something similar I

I wanted to group some functions which I use in some models in one place. Controllers have application.rb and views have helpers but I couldn''t find anything about models. Using the /lib directory seemed to be the only way. Alright... so I have something like this: /lib/code.rb class ActiveRecord::Base def method_a(n) ....... end def method_b(n) ........ end end

Hello all, just started tinkering with Rails after reading all the hype about it. I''m a raw novice with Ruby and (obviously) Rails, but have extensive experience with serverside Java (J2EE stack, Tapestry, etc). Rails looks cool, though embedding Ruby code in HTML reminds me unpleasantly of JSP + Struts and I''m deeply suspicious of all the behind-the-scenes magic going on in

I found a tutorial for creating classes using generic functions ? S3 way ! It was short description so I couldn't grok in full its usage ... So far so good, what i currently do is something like this : Blah <- function(data,...) UseMethod('Blah') Blah.default <- function( ...... ) { self = .... class(self) <- 'Blah' self } Blah.some_method <-

I have a simple question when to the synchronize method in the Mutex class. Now that backgroundrb has allow_concurrency = true there is no need to synchronize database calls in threads. The question I have is lets say I have a simple method in my worker as follows: def some_method SomeModel.find_all each do |obj| obj.some_count += 1 obj.save! end end It accesses the database, but

I have a method in a controller that invokes a render :partial => ''some_partial_view'' In that view, I''m trying to access a method defined in a model, like this; <% for view in @an_array %> <% local_var = view.some_method() %> <% another_var = view.a_column_name %> etc.. I am getting an undefined method error but the model is accessible

Hi Folks, I''m sure tons of people are gonna ruin a whole drawer of their best panties over this one. Rick Olson worked on the mongrel_upload_progress gem, documentation and examples and has almost everything you need to do progress tracked file uploads using just Mongrel to handle the upload. This means that Rails (or any other framework) isn''t blocked while the upload

I have a simple question. Let''s say I do this in one of my models: after_save drb_conn.some_method(self) end When that object gets over to the background process is it the exact same as?.... Model.find some_id #in the background process As far as my background process is concerned passing the object is not any different than passing the id and using the find method? Because

Hi, I wonder if there''s an easy way to access the associated Model class from its Controller. Something that would allow me to write snippets like the following: class PeopleController < ApplicationController def some_method person_model_class = self.some_method_to_retrieve_the_person_model_class() end end Cheers, Marco -- Posted via

Hi all, I know it may not have much sense thinking about a Singleton Pattern in an R application which doesn't use any OOP facilities, however I'm curious to know if anybody faced the same issue. I've been googling but using "singleton pattern" as a key word leads to typical OOP languages like Java or C++ among others. So my problem is that I'd like to ensure some very

I''ve setup two models, 1 and 2, that are associated by has_and_belongs_to_many. I''m trying to get an attribute from model_1 to use in a method in model_2. When I use the code below, I get an error saying ''undefined method model_1_id''. What am I missing? Thanks! Model_2.rb Class Model_2 < ActiveRecord::Base ... has_and_belongs_to_many :model_1 def

Hello everyone, I am operating a migration of samba from 3.0.24 (mysql passdb backend) to 3.5.6 (openldap passdb), samba working as a domain controller (PDC) and file share. The main challenge is to provide a seamless migration for users. For this new version, I am using smbldap-tools 0.9.6, nss_ldap, openldap 2.4. Everything run on FreeBSD 8.2. To get used to samba, I have managed to make

Whenever I tried to start mongrel_rails with the upload progress script, it would die with the following error: /usr/local/lib/ruby/1.8/drb/drb.rb:837:in `getaddrinfo'': getaddrinfo: No address associated with nodename (SocketError) from /usr/local/lib/ruby/1.8/drb/drb.rb:837:in `open_server_inaddr_any'' from /usr/local/lib/ruby/1.8/drb/drb.rb:860:in

Dear R-Help, I have a clustering problem with hclust that I hope someone can help me with. Consider the classic hclust example: hc <- hclust(dist(USArrests), "ave") plot(hc) I would like to cut the tree up in such a way so as to avoid small clusters, so that we get a minimum number of items in each cluster, and therefore avoid singletons. e.g. in this example, you can see

I''ve seen this come up a few times before on this list but never felt it got a satisfactory answer. What is the best way to execute timed actions? Examples include sending an email each week, calculating interest each day, or cleaning up your database or server files. This wiki page has some ideas, but these seem a bit extreme.
