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 all, I was a client site today on another project and we started talking about RoR. I wanted to show it in action, so I downloaded the one-click Ruby installer for Windows and then tried to do "gem install Rails -include-dependencies". After a time-out period I received the following error: ERROR: While executing gem.(Gem::RemoteSourceException) Error fetching remote gem

A client of mine has a ton of data stored in Excel spreadsheets. I''m building a web application for her (backed by a real db of course) and want to import all that data. Is there a library available to read data from Excel? Is there an easy way to upload the spreadsheets and then read the data? Thanks, Ken Kousen -- Kenneth A. Kousen, Ph.D. President Kousen IT, Inc.

Hi all, The Rails book talks about running Rails under Apache, but is there a (relatively) easy way to deploy it to either Tomcat or JBoss? Is the CGI servlet the only option?

I want to build an application that has the concept of administrative domains. What I mean by this is that administrators have access to different data, based on what domains they are a member of. The domain strucutre is hierarchical. Here is an example: - MLB - AL - East - Yankees - Red Sox ... + Central + West - NL + East + Central + West Now

Here''s something that caused me a couple of hours of head-scratching today: Apparently, if your model doesn''t derive from ActiveRecord, it is NOT reloaded for each operation in the development environment. I was working with something that uses a single model per session, and stores its data in the session. I kept wondering why I didn''t see my changes. Finally, I

Hi -- My book "Ruby for Rails" is now being released one chapter at a time through the Manning Early Access Program, with the whole book due to appear on May 1. If you''re interested, see http://www.manning.com/books/black (I guess I could have just sent my sig with no body, but anyway :-) David -- David A. Black (dblack@wobblini.net) Ruby Power and Light

Has a decision been made about the proper way to transfer RailsConf tickets from one person to another?  I didn''t see anything on the RailsConf site and the wiki just leads to the regular RoR wiki. It turns out a client of mine needs me that week.  I don''t mean to clutter the discussions here with that, but I don''t know of any other forum. Ken -- Kenneth A. Kousen,

How can I link to a CSS file in one of my view files? -- Posted via http://www.ruby-forum.com/.

Hey Folks, Now that all the fun and games of learning Rails has almost sunk in it''s time to build something useful. I am tasked with building a system to control and search our large (and I mean large 1.5 million + and growing) photograph collection. I have been building databases for years and after thinking about the situation we decided that trying to store the

As others have mentioned, Chapter 4 of David A. Black''s book _Ruby for Rails_ is now available for download from the Manning site. The fact that the book is being released one chapter at a time makes it easy to read in small, digestible chunks. I never intended to review every chapter individually here, but now that I''ve done the first three, I feel like I ought to continue.

Here''s my review of Chapter 3: As the author says, this is a transitional chapter. The first chapter was an introduction to Ruby, and the second was a similar introduction to Rails. Now we begin the real purpose of the book, which is to dig into the Ruby behind the Rails. Periodically the question arises on this list about how much Ruby you need to know in order to do Rails.

ANNOUNCING AGILE WEB DEVELOPMENT WITH RAILS, SECOND EDITION =========================================================== http://www.pragmaticprogrammer.com/titles/rails2/ Rails has changed a lot since we announced the first edition of the book a year ago.

Hi, I''m interested in using a currency conversion web service in my rails app. Does anyone have a free service that they use and like? I found this one http://www.webservicex.net/WS/WSDetails.aspx?CATID=2&WSID=10 I''ve tried to make a simple, plain Ruby script to connect to this and get a conversion rate without success. How do I integrate a webservice into my rails app? I

Hi, I''ve started reading some Java books. Gasp! What makes website development with Java so bad? I haven''t looked at Struts but I''m reading about Hibernate. Compared to ActiveRecord, Hibernate seems like some extra typing to explicitly define the model fields, getters and setters. I know that these are things that you can do in ActiveRecord when things get complicated

Hey, I have slow access when I first open shares. If I reboot my XP box and then go to access a share, it takes a good 10 seconds for files to come up, even after I've typed in my username and password. Once accessed it runs fine and is fast. But, if I don't access it for 30 minutes, when I access it again it sits for like 10 good seconds before it does anything. This is very annoying.

Using 2.2.1a and a 2.4 kernel patched for win4lin. Everything is working but: I mount all the available network shares on my linux box as root to one network directory. If a windows client shuts down while the linux box is still connected, the share is not removed from my mount list or from /proc/mounts It cannot be removed with umount. I can kill the smbmount with kill -15 but the share is still

I have a samba version 3.024 server joined to a ADS as a "Workstation or server" acting as a file/print server. It is a Debian 4.0 amd64 up to date with stable. ftp works just fine so not network, must be samba config. vary slow file transfer when copying file from one computer but copy from two or more at the same time speed is 10 times faster. You will be copying a 600MG file with one

Hello, Last week I have detected with Zabbix that a member of my Samba domain had been downloading at a rate of around 8 Mbps for two days and a half. When asking the person to whom belonged the machine, he didn't know he was downloading anything but he said he had observed his machine had slowed down since then. I took a tcpdump of the traffic before terminating his session on Windows

Would really appreciate it if someone could tell me why this is happening: I override ssn method of AR class so I can encrypt/decrypt to/from the db: class Person < ActiveRecord::Base def ssn=(value) write_attribute(:borrower_ssn, Crypto.encrypt(self.encryption_key, value)) write_attribute(:borrower_ssn_final_four, value[5,4]) end def ssn # this begin - rescue can be
