I''m having a silly little problem with migrations.  All I''m trying to do is to add an SSN column to my Employees table.  I generated a migration which looks like: class AddSsn < ActiveRecord::Migration def self.up     add_column :employees, :ssn, :string end def self.down     remove_column :employees, :ssn   end end When I run this, however, I get: >rake

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.

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, 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

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

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

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.

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

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

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,

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
