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

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

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.

MySQL too many connections?
Does any have any idea why I would get:
Mysql::Error: Too many connections
I am creating new threads in my background process. I know
allow_concurrency is set to true. Does this create a new database
connection when a new thread is created? Because what I''m doing is
similar to this:
@threads[model.id] = Thread.new do
end
I also kill off these threads and over write some of the

how about the global data when multiple backgroundrbs ?
Ezra,
Suppose a chatroom application, a RailsApp + 2 backgroundrbs: MiddleMan1&
MiddleMan2, running in 2 machines.
When Chater1 login, RailsApp call MiddleMan1 to get something about
Chater1 from db to memory, like his contacts or other personal settings.
When Chater2 login, RailsApp call MiddleMan2 do the same thing.
But who is reponsible for the Global Data? like a Online Chaters

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

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.
Thank You,

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

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?

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

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 =

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

Best way to sort the emails in a mailing list?
I know this isn''t really rails related, but I was wondering if anyone
had a clever way to sort out which mailing list threads they''ve been
involved with and which ones they haven''t. That way when a new email
comes in and its in a thread you''ve been involved with, you could
move it to another folder.
