Hi Guys

I am pretty new to Ruby. One of our client is using Firebird as his  
backend database. I have to create a script which will connect to his  
database, fetch some data and update few tables in MS-SQL database.

Now problem is: i have installed FireRuby, got databaes, changed my  
database.yml file.

I am trying to display all the users in Members table. but i am  
getting following error:

ActiveRecord::AdapterNotFound in UsersController#index

The Firebird adapter requires FireRuby version 0.4.0 or greater; you  
appear to be running an older version – please update FireRuby (gem  
install fireruby).

Please advice.

I have the unfortunate experience of working with Firebird/FireRuby

what version of FireRuby do you have installed? My current win32  
version is 0.4.1

try a “gem query list -n fireruby” from cmd

its the latest 0.4.1

but i have figured out the solution., I updated my environment.rb with  
FIRERUBY\_GEM\_VERSION = ‘0.4.1’ unless defined? FIRERUBY\_GEM\_VERSION  
and it worked

thanks
