Session access interfers with other model access
Sorry to be such a bother but I''m not getting this.
I have two models: Emrec and Session (I''m using AR for session mgmt.) In my
worker I can access the Emrec model and delete a record, AS LONG AS I don''t
try to access the Session model. With the Session model access commented
out as below, the Emrec record gets deleted. If I uncomment those lines,

error message for record not found ?
I''m using backgroundrb for session management and deletion of visitor-entered information when a session is abandoned. The visitor can either click a button to end their session and remove their data, or backgroundrb will do it for them after 5 minutes of inactivity.
Everything''s working fine, I think. If the visitor explicitly logs out, then when the worker checks for their

Need help understanding Rails magic!
Hi,
I''ve just been pleasantly surprised, again, by how much Rails does for me, but I am *really* surprised. Surprised as in "how the heck did that happen?" I''d really like to understand this and would appreciate any help.
Big picture... the user is presented with a form that allows them to select one or more check boxes to record their allergies. The form uses the

accessing args in worker
If, in the controller, I start a worker and pass in an argument like this:
session[:job_key] = MiddleMan.new_worker(:class => :foo_worker,
:args => {:emrec_id => @emrec.id})
How do I access the value in the worker? I can''t seem to figure it out ;-p
Thanks!

Server-side session management for short session expirations?
I need to effectively log a user out if their session is inactive for more than a short period of time, like 5 minutes. I need some help understanding how to approach session expiration and cleanup in Rails.
When the user explicitly logs out of my app, I delete all the data they''ve entered/that''s been created during their session. The data includes files, database records, and

Need help PLEASE!!! - updating collection from form
Greetings!
I''m trying to update a set of records from the same model on one form. The AWD book gives an example on p.356 but I guess I''m not understanding it.
I can see from the error message I''m getting that the controller is receiving a hash of hashes back from the view, and that it''s got the stuff I expected (two values per record that was sent to the

assignment of parent ID in child''s fk field
When I create a child record I''m not automagically getting the parent ID put into the fk field. Does object.new take parameters that allows me to do that as part of the AR record creation? Or do I need to do it separately? Or am I missing the boat altogether ;-)
Thanks,
Bill

Session magic question
Greetings!
I could really use some help understanding what Rails puts into the session store related to the objects it creates. I''ve found documentation on how _I_ can put / get info into it, but can''t find the docs on what _Rails_ puts into it.
I''ve got a simple app that collects some data from the user, stores it in a db record, allows the user to edit it, display

Using indexing to manipulate data
I know one of R's advantages is it's ability to index, eliminating the need
for control loops to select relevant data, so I thought this problem would
be easy. I can't crack it. I have looked through past postings, but
nothing seems to match this problem
I have a data set with one column of actors and one column of acts. I need
a list that will give me a pair of actors in each row,

RSpec view spec writing problem (unable to generate url_for in RESTful resource link_to)
Thanks, first, to everyone who''s asked and answered questions on this list,
and to the creators of RSpec - it is all very helpful. I''ve searched the

find an answer.

has_many :through and scopes: how to mutate the set of associated objects?
I have a model layer containing Movie, Person, Role, and RoleType,
making it possible to express facts such as "Clint Easterbunny is
director of the movie Gran Milano".
The relevant model and associations look like this
class Movie < ActiveRecord::Base
has_many :roles, :include => :role_type, :dependent => :destroy
has_many :participants, :through => :roles, :source

[LLVMdev] LLVM and coroutines/microthreads
I saw this was mentioned briefly last year, but there seemed to be
some confusion as to what coroutines entailed and the thread died out.
This technique has an unfortunate number of names, but it does get a
lot of use, including popular languages like Ruby.
I'm currently working on a programming language called Minnow
(http://www.minnow-lang.org). It's an actor-based language, where

accessing session data in worker
Is there something special I need to do to access session data in a worker?
I''m using an AR session store. I''ve been working with Ezra''s tutorial, modifying it a little here and there to figure it out. So I changed the progress bar to a simple count-down in the worker which sends back the count to display in the view. No big deal. But if I try to access session

n-way joins
Hi,
I''m somewhat of a Rails newbie and am trying to understand how to
formulate n-way (3 or 4 way) joins in Rails (where the join tables
contain extra data as well.)
Let me give you my basic entities:
foos
id - pk
name - unique
bars
id - pk
name - unique
bazs
id - pk
name - unique
frozs
id - pk
name - unique
then i have two separate join tables:
foos_bars_bazs - 3 way join

Mongrel says it works, but it doesn''t

webrick never worked and instantrails for rails was very slow. the problem
with webrick is/was is that it says just this:
