Separate database for active record versioning using paper trail gem

I'm trying to log the change events of a model in a separate database using papertrail.

I'm using Rails 4.1.2

Ruby 2.1

Papertrail 4.0.0

Below is the code i have added in concerns

module Foo
 class Base < ActiveRecord::Base
 end

 class Version < Base
  include PaperTrail::VersionConcern
 end

 class Topic < Base
  has_paper_trail class_name: 'Foo::Version'
 end
end
Foo::Base.establish_connection(:trail_development)

I have included this Foo in topic.rb

class Topic < ActiveRecord::Base
 include Foo
end

Whats wrong?

Solution

  • After looking at some of the tests within the paper_trail gem I found an example spec that tests what you are trying to achieve: https://github.com/airblade/paper_trail/blob/v3.0.0/spec/support/alt_db_init.rb
