similar to: redhat being sued over use of ORM/ActiveRecord Pattern in hibernate...could RoR be next?

For those haven''t seen it yet, Patrick Peak has an interesting article at the Server Side (www.theserverside.com) discussing the differences between the Hibernate (www.hibernate.org) peristence framework and ActiveRecord.  The article can be found here: http://www.theserverside.com/articles/article.tss?l=RailsHibernate .  Patrick Peak is the author of _Hibernate Quickly_ (Manning), which

Hi I have this "old" database mainly modeled for Hibernate. The java model has something called Asset. Asset is inherited by SomeAsset and AnotherAsset and the similar stuff is in the asset table and the specific data for SomeAsset is in table some_asset and for AnotherAsset in another_asset. This is then reflected in hibernate using a <joined-subclass/> element. What would

For a company study I am trying to come up with what would one need to replicate *grosso modo and at the functional level* what we get in Rails. This does not need to be an "equivalent" solution, just what a Java programmer would build upon, the canonical aggregation of components, the usual tools. My first fraft is: Struts -> C layer Hibernate -> M

Hi guys, can''t get RoR updated after 0.10.0 also rails -v gives "version unknown". Any hints? Lorenzo rails (0.10.0) Web-application framework with template engine, control-flow layer, and ORM. rails_analyzer_tools (1.1.0) Tools for analyzing the performance of web sites.

I''m new to RoR and going through the tutorials trying to learn as much as possible. I have actually two questions: 1. What is a proper way to deploy an app into the PROD environment? Here is what I''m trying to avoid: when writing/testing application (ie. new user signs ups) on my local machine, I don''t want these users to be deployed into the PROD environment along

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Everyone, Want to let you know that I''ll be syncing over all the aspects of RoR''s mailing lists and it''s site onto a new dedicated server that''ll just be for RubyOnRails.org/.com. It''ll all be seemless and kept in sync until David flips the DNS switch, but there will be a couple of times where the

We''ve all seen the productivity benefits of RoR. It would be worthwhile to figure out where they come from. For me, I''d say the following: 1. The number one benefit isn''t from Rails per se, but from Ruby, or any other dynamic OO language (like Python). They avoid the weaknesses of loosely typed, procedural languages like Perl & PHP, but have the swiftness

Hi, Does anyone know of an R ORM (Object Relational Mapper)? I'm thinking of something similar to sqlalchemy (http://www.sqlalchemy.org/). Alternatively or additionally, can people offer suggestions about managing relational databases from R. I'm currently using postgresql, but would like a flexible solution that works across different databases, hence the enquiry about ORMs. Please

Quick question on this query: @item.entries = Entry.find_recent(@td.id, 10) || [] My development log file shows that rails makes 2 calls to database! Is rails ORM not smart enough to know to not load the lvalue of assignment thus causing another expensive db call? Below are the stubbed models and a log snip. class Entry < ActiveRecord::Base belongs_to :tracking_definition def

I''m a Django/Catalyst user that''s evaluating Rails ... I need a Ruby framework, and I''m trying to see if learning Rails is worth it or I should just go for Sinatra + various libs available. Django has a couple of things I like ... 1) the Forms API In Django I like that it''s being decoupled from models ... form objects have fields with validation rules that

[Apologies for cross-posting] Hi everybody, I am part of the Spatial Information Systems Group in University College Dublin.

Hi everyone, I am attempting to connect an already existing mysql database with Rails. For This I can''t use the traditional "generate scaffold" and "rake db:migrate" because (I think), I''ll loose the data already existing in that database table. So what I did was, I generated a scaffold for my table, and instead of running db:migrate, I added a

I''m curious -- how many of us came to Rails from other branches of the OO world -- Java, C# -- and how many of us came from the design or non-OO scripting worlds? Reason I ask is that I''m finding Rails a blast and very productive, but I think one reason is that I already cut my teeth on MVC and ORM during two years of writing apps with J2EE/Struts/Hibernate. And in Javaland, it

The RHEL 5 release notes for their desktop version claim "Improved ACPI support with features such as suspend to disk" but this isn't working with CentOS 5. I've installed all the packages and updates for CentOS 5 i386 on a ThinkPad T43 but when selecting suspend, Gnome pops up a URL to a site that didn't seem to give a solution. Gnome makes an entry in /var/log/messages

Hello, I have a few models -- book, cd, dvd -- for which I''d like to have an abstract base superclass to hold some common stuff. That abstract class, I was thinking, would inherit from ActiveRecord. Didn''t work, though, and looking around, I found this: <http://wiki.rubyonrails.com/rails/pages/HowtoMakeAbstractModel>

Hi, I have successfully crossed all the hurdles to install Ruby on rails on a redhat 5 Linux based system. But the last and the biggest hurdle i am facing at this moment is installing backgrounrb :( I followed all the steps from the http://backgroundrb.rubyforge.org/ 1. sudo gem install chronic packet 2. script/plugin install svn://rubyforge.org/var/svn/backgroundrb [IMP:::: I had to drop

I''m trying to get some answers as to why I (my company actually) would go with RoR over TurboGears. The developer staff is fluent in both Ruby and Python so that is not an issue. Rails is well into its release cycle whereas Turbogears won''t be at 1.0 until later this week. They both do essentially the same thing and they both have cool features unique to themselves

Hi, Over the past month I''ve been playing with some ideas for an admin interface for a ecommerce app. 1) Old-fashioned, forms-based, full-page-refresh, server-focused interface 2) Modern, JavaScript-Drag-Drop, AJAX, client-focused, Web2.0 interface The more I work on the second option with JavaScript an AJAX the more I feel like I''m moving away from building a server side
