This works until you update… I think you need

def users
@users ||= order_users.collect(&:user)
end

i’m using
establish_connection(ActiveRecord::Base.configurations["legacy_#{RAILS_ENV}"])
inside my legacy models so you can use a development and production legacy database

I think that the code

def orders
order = []
order_users.each do |ou|
order << ou.user
end
order
end

should be

def orders
order = []
order_users.each do |ou|
order << ou.order
end
order
end

I second the "embrace collect" advise. To make this advise somewhat clearer to mere mortals, here's a rewrite: def users users ||= order_users.collect {|ou| ou.user} end For clarification of the ampersand (&) notation, please see here.

embrace .collect:

def users
users ||= order_users.collect(&:user)
end

def orders
orders ||= order_users.collect(&:user)
end
