Hi All,

I am a newbie in Ruby-Rails. Actually we are using postgre SQL and Ruby  
application to access the DB. I have made the controller and the model  
classes. My database.yml contains:

development:  
adapter: postgresql  
database: test  
username: poc  
password: poc  
host: localhost:5000

test:  
adapter: postgresql  
database: test  
username: poc  
password: poc  
host: localhost:5000

production:  
adapter: postgresql  
database: test  
username: poc  
password: poc  
host: localhost:5000

I have actually configured my postgresql to listen to port 5000 rather  
than 5432(default). When I hit the url [http://127.0.0.1:3000/Testing/new](http://127.0.0.1:3000/Testing/new)  
it is showing an error:

Bad file descriptor - connect(2)

My model → testing.rb

class Testing \< ActiveRecord::Base

end

My Controller → testing\_controller.rb

class TestingController \< ApplicationController  
scaffold :testing  
end

How can I resolve this problem… Thanks in advance…

Regards,  
Janeve

you are probably running on a windows platform using ‘instantrails’ and  
you didn’t run the application. (you have to run the red “I” icon in the  
instantrails folder - - it connects all of the applications together -  
sql, application, rails, etc)

hope it works.
