Rails and background tasks/threads
I am just getting into web servers/web applications and rails as well so bear with me. I am trying to write a web app that, based on a users input from the browser, will perform some task, and update the browser (ala ajax style) as needed and/or provide a way for the user to control the background task. Now, I have more experience with java servlets, which makes this easy enough for a beginner.

Serialising multiple accesses to external web service
Hi all, I have an external web service that I need to log into at a specific part of my web app,. The problem is that I only have one login to this web service, and if another login attempt is made while an existing login session is still active, the existing session gets terminated.

Update
Folks- I just commited another revision of the plugin. Nothing huge in this update but some extra features. Acl lists are now configurable in the config file. So you will want to blow away and recreate your config file again. Thanks to Georg Friedrich for this. And I applied Gunter Ladwig''s patch for singleton worker classes. These are workers that only have one instance of

What is SpecServer?
I have looked through the docs, looked at the code, even gave a cursory (2 page) glance at google, and it is not clear to me what SpecServer is or what it is for. Is it meant to speed up the execution of specs in a rails environment by doing some magic on the database? Or I am thinking it keeps a copy of Rails running to avoid the rails reload delay... Is there any documentation on this so I

Worker-be-gone
Hello, Thank you so very much for Backgroundrb. Good Stuff. A general question: Do: - calling ''teminate'' within a worker - calling delete_worker through MiddleMan - letting the :ttl expire - calling MiddleMan.gc! (with an appropriate timestamp) All accomplish the same thing? And here''s a bonus feature request: It''d be cool if you could specify how many

Very strange after_save problem. Please help.
I have a very strange problem here. I do not get this. So any help is greatly appreciated. Basically I have a model that calls a method in the background process in the "after_save" method. Let''s call the model products. So what happens is this: 1. I create a new product. 2. Everything works and the product is saved with id 13. 3. A method is called in my background

Support for processing after the response has been transmitted?
Hi, Is there any interest in allowing controller methods to do post-response processing? This would be useful where some time-consuming statistic or index processing should be done after the response has been sent so as not to delay a response that does not depend on that processing. This could be implemented by allowing the action method to yield to the process method which in turn yields to a

Multiple backgroundrb servers?
What are people are doing when they need to deploy a new code base? You can''t just restart backgroundrb, because then you lose any long-running backgroundrb processes. But then you''d conceivably have to wait several hours for all your procs to complete before pushing out the new code base. I was originally thinking that during code deploys, we''d start up a second

Relationships question (?)
Hello there, Im currently taking a Senior Design Course at my college. We are developing an online document editor prototype with Rails. I am not well-versed in Rails. As a matter of fact, we chose it for the project in order to learn it. The problem we have is the following: We have a User model (id, username, password, email) and we have a Document model (id, name, content, owner_id). A

Tricky model situatione
I have two models Club and users. users are regular authenticated users and some of them might create a club. A club can also have members (essentially users) and there are attributes and models that apply to member but not to users. Here is what I have right now. Club => belongs_to :user User => has_many clubs (since a user can host multiple clubs). Now how do I fit this member model

Applicationwide BusinessObject/Hash
Hello, I''m a total newbie, so please forgive my ignorance. I am trying to port an application from java to ruby. In order to do that, I need to put the object containing all the business logic into something like application scope. The nicest solution would be just to have an application wide hash, where I can put all kinds in of objects. Where and how would I instantiate such an

drb problem? ringy-dingy won't answer...
The following code works fine as long as I don''t try to run it through the distributed server. It doesn''t get there... It runs fine out of delayed_job, runs fine if called directly. But if ''distrib'' is true (the default) it runs right up to the call to the server and right past it without getting to the server or raising any errors. Am using Ruby 1.8.6.26 ,

Adding to model (newbie)
Sorry if this is a really lame question, I''m sure it''s something fairly obvious, but I just can''t see it at the moment... I''m trying to add something simple to the model for a project management/todo list/thing. The DB has ''first_name'' and ''last_name'', and I''d like to have "full_name" available. So -
