Ezra....allow_concurrency = false?
In a previous email you wrote this: Glad you''re getting some use out of the plugin ;) ActiveRecord does have some issues with threading and concurrency that can sometimes cause that error you are seeing. Open up your script/backgroundrb/ start file and comment out the following line: ActiveRecord::Base.allow_concurrency = true Make sure you do that up in your main app script folder

When to use Mutex::synchronize?
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

Impossible to get stable?
I have concluded that it is impossible to get this background process stable. I am out of ideas and could really use some help. Here is what I have: 50 workers, just running an infinite loop that constantly calls save! on a model. Keep in mind this is just for testing purposes. I catch all exceptions and put them in the log. I am tried setting allow_concurrency to true and false. Neither

Creating workers from workers?
Since MiddleMan is an uninitialized constant in a worker how do you create new workers inside a worker?

delete_worker doesn''t kill the thread?
I made a worker that run an infinite loop and does the following: while true @logger << "logging #{Time.now}" sleep 2 end In my secong console I did: tail log/backgroundrb.log -f This is so I could see the line getting added to the log every 2 seconds. Then in my other console I started script/console and created a new worker. Then killed it with

Please help, if @jobs[key].respond_to? :thread is returning false
I noticed in the BackgroundRB class in the delete_worker method there is a line: if @jobs[key].respond_to? :thread For some reason this is returning false for me, it gets down to this line and returns false, not killing the thread. Any idea why this is returning false? Thanks for your help. Thank You, Ben Johnson E: bjohnson at contuitive.com -------------- next part -------------- An

Debugging a worker?
If there is an exception raised in my worker I rescue it and throw it into the log. This is decent, but it would really help to find out more information. Like the line number, the stack trace, etc. Is this possible? Thanks for your help.

ActionMailer doesn''t work in backgroundrb
I am pretty confident that mailers do not work in backgroundrb. Can anyone confirm this? Because when I try to do Notifier.deliver_some_method I get an error saying it cant find the templates for my email. The funny thing is that when I run script/ runner Notifier.deliver_some_method it works just fine. Any ideas? Thank You, Ben Johnson E: bjohnson at contuitive.com O: 800-341-6826 M:

Accessing the controller name in your views?
I need to know what controller and action the user is currently in to do various things in my layouts/application.rhtml file. Isn''t there is a better way than: <% if params[:controller] == "whatever" && params[:action] == "whatever" %>some html<% end %> I know in the controllers you can just use controller_name, but that is not provided

Just a tip
I figured instead of asking a question I would share some useful knowledge I learned this week. Maybe you already know this, maybe you dont. If you use backgroundrb to run an "infinite" loop, or create many threads, or do quite a bit of processor intensive tasks, and you notice that its running kind of slow, it might not be a bad idea to have multiple backgroundrb processes

Passing objects to drb, does it keep the existing db connection?
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

How to add validation to in_place_editor
I have a simple question, but can''t seem to figure this out. I added an in place editor field and didn''t like how it didn''t use the save method. It uses the update_attribute method which does not run validation, etc. So I just added the method in my controller myself: def set_event_url begin @event = Event.find params[:id] @event.url =

Catch 22 with after_save. Please help.
I have a pretty strange problem. Here is basically what I have to demonstrate my problem: class Event < ActiveRecord::Base def after_create AnotherClass.find_event(id) end end class AnotherClass < ActiveRecord::Base def self.find_event(event_id) e = Event.find event_id end end Here is the catch 22 and it''s quite annoying.

Problem with drbundumped?
I''m not sure if this is a problem or not, but it definitely henders the way one would use the passing of objects to the drb server. Isn''t the point of passing objects to the drb server to act like its passing to just another local method? When I pass an object to the drb server a lot of the useful methods are gone. Such as id() or class () or inspect(), etc. I spent a

How to use variables in your layout views?
Let''s say I wanted to find 3 products from my database and put them in the layouts/application.rhtml view. Where do I find these 3 products? Do I just do it in application.rhtml? <% for product in Product.find(:all, :limit => 3) %> Because I was under the impression that you really don''t want to do this in your views. You should do this in your controllers and
