Hi, As I understand, composite primary keys aren''t supported in ActiveRecord yet. May I ask if there are plans for this feature? Better yet, if this feature is under development, how''s the progress going? I''m not trying to use legacy databases. I tend to think that using multiple integer column id''s (composite primary key) are often natural way to

Hi friends, i am using csv export on my application. in my view file code is <%- headers = ["Transaction ID", "Activity ID", "Product Name","Customer Name", "Ticket code"] -%> <%= CSV.generate_line(headers).strip %> <%if !@trans.nil? && @trans.length > 0 %> <% @trans.each do |tran|%> <% if

Hi, I''m wondering if it is possible to pass an extra value (which I will use to further restrict my query) using text_field_with_auto_complete? Any suggestions would be appreciated! -Mike

Hello, I have an application that access two different DBMS - Firebird and Postgres. So far, that''s ok. The problem is, depending on the customer logged, a different database (Firebird) must be selected. To make the things clearer: Postgres: 1 database shared by all customers with these tables: - user - vehicle - driver Firebird: several databases with different names and identical

Dear R, Short verse of the question: Is there R code which will calculate surrogate splits and/or delta impurity for decision trees at each node? Long Version: I have local, legacy code which I use to calculate my decision trees. I would like to switch to R, but as I understand it surrogate splits are not implemented. Surrogate splits and feature ranking are described in Breiman et al

Hey guys, I''ve been trying out ferret 0.9.3 on my powerbook this weekend and I''ve been triggering ''bus errors'' when using the Query API. If I programmatically build up strings, it works just fine. There''s some more information available in the trac ticket http://ferret.davebalmain.com/trac/ticket/62 Is anyone successfully using the Query API on

Filter chaining appears to behave in differently than Rails 1.2.x. It seems that I''m getting a lot of errors along the lines of: ActionController::ActionControllerError: filter #<ActionController::Filters::ClassMethods::BeforeFilterProxy:0x322f468 @filter=#<ActionController::Filters::ClassMethods::SymbolFilter: 0x322f4b8 @filter=:login_required>> was in the wrong place!

I''ve upgraded to mySQL 5.0, and it''s gone pretty smoothly except that on DateTime.now doesn''t seem to return a value that mySQL likes any more, as seen in the following exception: Incorrect datetime value: ''2005-11-20T15:33:12-0800'' for column ''logged_at'' at row 1: UPDATE notes SET `due_on` = ''2005-11-20'',

Yesterday I answered a question regarding polymorphic URL helpers on Core ML and noticed that the module has no documentation. I''ve documented it and rewritten unit tests using Mocha. I also optimized some of the code slightly (nothing major, though). The patch also includes two fixes by Geoff Buesing, who has done awesome work in this area in the past.

Hello all, I am working on building a web store with RoR. The company has many locations. All the stock/order information is processed through the same site. Here is my question. How would you handle the multiple warehouse problem with Rails? How would you keep track of the information in multiple warehouses? Thank you for your help, PV -- Posted via http://www.ruby-forum.com/.

I''m having a wee bit of trouble building documentation for Edge Rails (rev 7187). When I attempt to run the doc:rails taask (or any doc:* task), I get the following error: -- BEGIN -- rake aborted! uninitialized constant RubyToken::AlreadyDefinedToken /Users/jherdman/Projects/crosslisting/vendor/rails/activerecord/ lib/../../activesupport/lib/active_support/dependencies.rb:263:in

I know why SQLite3 is broken. This code: Topic.transaction do |transaction| transaction.rollback! end results in the following database commands: BEGIN; ROLLBACK; COMMIT; In other words, there is a COMMIT when no transaction is in flight. MySQL and Postgres are coll with it, but SQLite3 blows up with indignation. Recorded as a ticket: http://dev.rubyonrails.org/ticket/8030

I just noticed I frequently encounter patches that need to be updated because of applied changes. Maybe this can be automated? Not automating the "updating of the patch" part, but the part where a comment is posted to the ticket so the submitter is informed. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups

Hi everyone. This is a real noob question that I''m hoping someone out there can help me with. I have followed the tutorial How to Ad created_by and updated_b<http://wiki.rubyonrails.com/rails/show/Howto%20Add%20created_by%20and%20updated_by>y and it works ok for retrieving the data. I''m using the Login_Generator. I cannot get it to work on create or update. I think

It seems odd to me that the layout is processesed after the view. When I set a variable inside the view it does not have an impact on the layout file. But when I set it in the controller it does. Is this the way it works or is it possible that I am doing something wrong?

I was working with acts_as_taggable earlier and thought I could make it a bit friendlier. I submitted a ticket and patch #8279. Basically, there are three differences. 1. Fixed the deprecated :dependent => true 2. Added migration generator (it has really specific requirements on table layout, so might as well generate it). 3. Expanded the README to explain using the migration and to include

Dear R-help, I would like to compute the variance for the proportion of treatment effect by a surrogate in a survival model (Lin, Fleming, and De Gruttola 1997 in Statistics in Medicine). The paper mentioned that the covariance matrix matches that of the covariance matrix estimator for the marginal hazard modelling of multiple events data (Wei, Lin, and Weissfeld 1989 JASA), and is implemented
