Rails RSpec with Multiple Databases

Question

I run a Rails app, and we\'re in the process of splitting out our signup process to a separate app. The signup app has its own separate database (for CMS and collecting prospect

Answer 1

Here's what I came up with as a mixin:

# lib/establish_connection_to_master_database.rb
module EstablishConnectionToMasterDatabase
  def establish_connection_to_master_database

    case RAILS_ENV
    when "development"
      establish_connection :master_dev
    when "test"
      establish_connection :master_test
    when "production"
      establish_connection :master
    end

  end
end
ActiveRecord::Base.send(:extend, EstablishConnectionToMasterDatabase)

# models/subscription.rb
class Subscription < ActiveRecord::Base
  establish_connection_to_master_database
end

# config/initializers/config.rb
require 'establish_connection_to_master_database'

In order for this to work with RSpec, this needs to be loaded in an initializer - apparently loading it in the environment file causes it to be loaded it too late, and it won't work.
