Hey, I have got a script that returns a long list of font family names, which I all want to store in a variable (array). I tried doing this with @f = font.family also in the for loop below but it only prints the last item when I want to display the results. require ''rubygems'' require ''RMagick'' include Magick for font in Magick.fonts puts font.family end

I want to copy data from one database to another using rails. But, it seems that rails only will talk to one database at a time. Is there a way around this?

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

Hi, I would like to turn some of our simulation codes out to pasture and string some of them together by draping them in web services. I''m looking for a RESTful Camping tutorial to get started ... pointers appreciated. Some simple example applications: airfoil force calculator: feed it an airfoil geometry, an angle of attack, and a Mach number, and it returns the lift, drag, and

So, is there a summary of the changes since the first edition? It would be helpful to see just exactly what in Ruby on Rails has changed before ordering the second edition of the book. Could somebody briefly describe changes to Rails since the version covered in the first edition of the book?

...out nicely using a "establish_connection" per model, where each model enherit directly from ActiveRecord::Base. But ! I like to use a model where we can inherit from one parent class that handles the connection exactly as descripted in this document : http://blogs.pragprog.com/cgi-bin/pragdave.cgi/Tech/Ruby/Connections.rdoc The only problem is that my database (postgres) seems to be asked to find this parent class, but this should not have happend !

Hi all - New to rails... been reading as much as I can though and have yet to find a solid answer (although I think I found an unsolid negative). I''m wondering if there''s a way to split up the reads and writes in Rails so that pages/actions that don''t need to write can query from a group of mirrored databases. And my content managers can update a single master. I

With after triggers in Postgres, there are special NEW and OLD vars accessible to trigger functions. Any such thing in Rails? Or would it entail doing something like setting a class var in before_update? Jack -- Posted via http://www.ruby-forum.com/.

Does anyone know if it''s possible to use Active Record migrations in a non-Rails Ruby application (including ActiveRecord of course).

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.

Hi, Has anyone tried to embed rails into a Cocoa app? I have got this working to a very primitive point using RubyCocoa. After about half an hour of playing I was able to get WEBrick to serve the rails starter page inside of a Cocoa app, but that is as far as I have got. I have an idea for a client/server app where the server is a Cocoa application that embeds WEBrick (or another server solution

Hi everybody, I''m experiencing trouble when trying to use ruby-postgres with a legacy database I need access to. To me it seems the problem is the VARCHAR columns used there as primary keys. On a simple me = User.find(''PS12345'') I get a type error exception with the message ''can''t convert String into Integer''. The trace is:

Not sure if this is old news or not, but it would appear that both the Ruby Cookbook and a Rails book are now available for purchase at O''Reilly Rough Cuts (something akin to PragProg''s beta book program): http://rubyurl.com/nHz http://my.safaribooksonline.com/?mode=roughcuts&srchtext=ROUGHCUTS I haven''t tried them yet, but it definitely seems worth checking out.
