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

How-to question: form creation / different table update
I could use some direction. I need a form to collect information on a user''s allergies. I want to present them with a form much like the one we fill out when we see a new doc where you just check-off the things you''re allergic to. When the form comes back to the controller I want to add a record to a table for each allergy they''ve checked. I was thinking I should

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

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

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, the Emrec

GLM FITTED VALUES TABLE
Hi all I have the following generalized linear problem. In a study of allergic responses, patients arriving at a clinic in Groote Schuur hospital were tested for sensitivity to a number of substances. Three of these were moulds: Cladosporium (C), Alternaria (F) and Aspergillius (T). Their level of sensitivity was measured on the Rast Scale as: 0: not allergic 1: mildly

trouble creating new records
Is it possible to create / save a new record from a controller other than the one I specified when I created the scaffolding? My situation is that I have two tables. Emrecs is the parent. Actors is the child and has a foreign key named emrec_id that references emrec.id. I scaffolded both, creating controllers and views for each. My app collects info from the user to fill in the two tables,

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! Bill -------------- next part -------------- An HTML attachment was

Pan in 6.2??
I can't seem to get a way to install Pan in CentOS, and I need it badly. I follow most busy lists, including this one, on Gmane using Pan (and, no, Gmane per Web is no use to me. I have some obscure allergy to webmail). Does anyone know an rpm (one of Fedora's, for instance) that I can install and not immerse myself in dependency hell?

Hi, This is an announcement for a package that has been up on CRAN since March 2006 but was never announced. The package is Mchtest - for Monte Carlo hypothesis tests allowing sequential stopping. The idea is to use the sequential probability ratio test boundaries to stop resampling for a Monte Carlo hypothesis test such as a bootstrap or permutation test. This means that you will take many
