Hello Javier,
I was just checking the set_table_name class method of ActiveRecord and I
think that could work for you:
class AnotherClass < ActiveRecord::Base
has_one :worker
end
class Person < ActiveRecord::Base
def something
self.name
end
end
class Worker < Person
set_table_name "workers"
end
w = Worker.create(:name => "WorkerName")
p = Person.create(:name => "PersonName")
ac = AnotherClass.create
ac.worker = w
ac.save
ac.worker.something # => "WorkerName"
I hope that would be helpful
