I have the following models.
# app/models/domain/domain_object.rb
class Domain::DomainObject < ActiveRecord::Base
has_many :links_from, :class_name => "Link", :as => :from, :dependent => :destroy
end
# app/models/link.rb
class Link < ActiveRecord::Base
belongs_to :from, :polymorphic => true
belongs_to :object_value, :polymorphic => true
end
Problem is, when I do the following, the from_type doesn't prefix the Domain namespace to the model e.g.
Domain::DomainObject.all(:include=> :links_from )
That causes the following SELECT:
SELECT `links`.* FROM `links` WHERE (`links`.`from_id` IN (5,6,12,13,18,24,25,27,29,30,31,32,34,35,39) and `links`.`from_type` = 'DomainObject')
The query should be:
SELECT `links`.* FROM `links` WHERE (`links`.`from_id` IN (5,6,12,13,18,24,25,27,29,30,31,32,34,35,39) and `links`.`from_type` = 'Domain::DomainObject')
because Rails automatically saves the model with the namespace.
I've seen a few recommendations on Rails sites about doing something like this:
belongs_to :from, :polymorphic => true, :class_name => "Domain::DomainObject"
However, that doesn't appear to work either.
So, is there a better way to do this? Or is this not supported?
