Establish_connection issues

Hi,

I have created a new app but I would like to use some database tables
from another application - so I am trying to use establish_connection

Here is my code…

Model file

class User < ActiveRecord::Base
establish_connection :external_database_development

Database.yml


standard configurations that will run the rest of the app

external_database_development:
adapter: postgresql
database: name_of_db
username: postgres
password: mypass
host: localhost
port: 2810

When I try and load my app I get a 500 error.

Status: 500 Internal Server Error
external_database_development database is not configured
