Catch 22 with after_save. Please help.
I have a pretty strange problem. Here is basically what I have to

def after_create
AnotherClass.find_event(id)

def self.find_event(event_id)
e = Event.find event_id
end

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

undefined method `'' for #<DRb::DRbUnknown:0x2501bd4>
I tried installing BackgrounDRb today. Followed the readme, made a
little worker for myself and executed it within the code. But I keep
getting this error. I must''ve gone over the README a zillion times.
Any idea what it is?

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

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

''m having trouble with BackgrounDrb
Hi. I thought that BackgrounDrb was the perfect solution for my long
running report production tasks.
But I can''t seem to get anything useful back out of it.
I set up a simple test worker that just does

"include DRbUndumped" error
Hi,
I am getting my hands on trying the cool BackgrounDrb plugin.
Following various discussions and suggestsion, I included "include DRbUndumped"
in my ActiveRecord model. However, the following exception occurs
after I tried this and hit the page that uses this model. Does anyone
know why this is so? Is it possible that an object cannot be

Cannot invoke ActiveRecord subclass accessors in DRb worker
Hi there,
I''m trying to create a worker to do some asynchronous web client work
and update the data model with its results. It seems, however, that
every call I make to an ActiveRecord subclass causes the whole thing
to block. At least I think it''s blocked. Right now I''m just using
debug log output.
Is there a decent way to debug/test workers I can try?
Is there any

Thanks for your help.

A couple of problems
Hi Ezra,
Thanks for the great work on BackgrounDRb. I have come across a
couple of problems.
1. I wanted to define a simple class in the worker file to wrap up and
pass back some data to my controller. It seems that if I create the
class either inside or outside of my worker class (in the same file)
it gets wrapper by a DRb::DRbUknown object and therefore cannot be
accessed from my controller.

Problems with ActiveRecord in workers
Hi *,
are there some special settings except of "load_rails: true" to make
ActiveRecord models accessible within my workers?

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 ,

after_save deletes is an exception is raised?
Does after_save in a model delete if an exception is raised in there?
I simply did
def after_save
raise ''hmmm''
end
and it raised the exception but there was nothing in the database. I
removed that entire method and its in the database. Is this correct?

Testing worker classes
Hi,
Does it make sense to test a worker class by calling
Middleman.new_worker? Or should I just be testing the functionality in
the do_work method, with, say, a mock object. This seems like a really
ugly DRY violation: you''d need to keep the code in the mock and the
real worker in sync.
That''s the philosophical half of my question. In fact, until someone

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 =
