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

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

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

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

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 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?

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 folks, I''m a newbie in the Ruby land, The Ruby language and RoR looks really great but I think in my situation there is a problem, we are an ISV that sells web application and we don''t want our clients see our source code, I searched the web but couldn''t find any way to compile and\or obfuscate ruby code (in web (RoR)), is there such tool available for the language?

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

Well now that I got your attention.... Why RoR sucks: 1. It''s smarter than me. Just when I think I''ll have to do some mundane thing (like I use to in PHP or ASP), I find out RoR does it already for me. 2. It takes about half or less code to put my stuff together in RoR than it did in PHP, ASP, ASP.NET, etc. It seems so unnatural that I can have a method with only 4 lines

I''ve seen some reports of problems with running Rails (version 1.0 here) on Ruby 1.8.3. Is this true across the board or just Mac OS? I''m setting up a Linux server and want to know if 1.8.3 is ok on that. Thanks, Jamie

Hey All, I'm trying to use the xlsx package to read a series of excel spreadsheets into R, but my code is failing at the first step. I setwd into my the directory with the spreadsheets, and, as a test ask for the first one: read.xlsx(file = "Argentina Final.xls", sheetIndex = 1) I promptly get an error message: Error in .jcall(row[[ir]],

I have a customer that I''m developing a solution for on RoR. They have IIS today and use Sharepoint for their intranet. Is it possible to have some kind of single sign-on between these systems? So when a user is logged in to ther Sharepoint she will also be logged in to my rails-app? We haven''t decided yet on what to deploy rails on so I''m open to suggestions... If we

Hi sorry for the slighty out of topic question but I''m sure someone here will be able to answer. Does anyone use some kind of remote connection to connect to MacOS ? I''m thinking of using VNC but I''d love to hear from other (especially secure) alternatives. I''m just fond of textmate, I have a dell laptop which I''d like to use as a terminal. kind

As far as I have been able to figure out, dovecot auth always works over a Unix domain socket. I believe it is not currently possible to operate dovecot auth over an Internet domain (TCP) socket. Am I correct? I want to call dovecot's exported authentication from a Java application. Java doesn't natively know how to talk to a Unix domain socket, so there are inconveniences. There
