Polymorphic class moved to Legacy Module and is looking for polymorphic type Legacy::Class instead of Class

Question

I moved the legacy code into a Legacy Module which uses a separate read-only database (the old MySQL database) as we have moved to PostgreSQL for the new version.

Everything queries fine until we get to the Polymorphic associations. It wants to look for eventable_type: 'Legacy::Schedule' instead of just 'Schedule'.

I could do an update on the field to change to 'Legacy::Schedule', but I don't think that is the cleanest solution. I would like to just modify the ActiveRecord query in the API or if there is a relations hack I would prefer that also.

Here is example of what I have:

class Legacy::LegacyData < ActiveRecord::Base
  self.abstract_class = true

  case Rails.env
  when "production"
    establish_connection :legacy_production
  when "development"
    establish_connection :legacy_development
  when "test"
    establish_connection :legacy_test
  else
    puts "connection: Rails.env error on establish_connection"
  end
end

,

module Legacy
  class Event < Legacy::LegacyData
    belongs_to :eventable, polymorphic: true
    ...
  end
end

,

module Legacy
  class Schedule < Legacy::LegacyData
    has_many :events, as: :eventable

    ...
  end
end

Answer 1

Inside Legacy::Event

def eventable
  if self.eventable_type == 'Schedule'
    Legacy::Schedule.find(self.eventable_id)
  else
    Legacy::OtherClass.find(self.eventable_id)
  end
end

UPDATE:

This is incomplete. Does not account for instance when Legacy::Schedule queries or builds on its events association where it then still queries for Legacy::Schedule
