rails HABTM versus view (formtastic)
- by VP
I have two models:
The model NetworkObject try to describe "hosts". I want to have a rule with source and destination, so i'm trying to use both objects from the same class since it dont makes sense to create two different classes.
class NetworkObject < ActiveRecord::Base
attr_accessible :ip, :netmask, :name
has_many :statements
has_many :rules, :through =>:statements
end
class Rule < ActiveRecord::Base
attr_accessible :active, :destination_ids, :source_ids
has_many :statements
has_many :sources, :through=> :statements, :source=> :network_object
has_many :destinations, :through => :statements, :source=> :network_object
end
To build the HABTM i did choose the Model JOIN. so in this case i created a model named Statement with:
class Statement < ActiveRecord::Base
attr_accessible :source_id, :rule_id, :destination_id
belongs_to :network_object, :foreign_key => :source_id
belongs_to :network_object, :foreign_key => :destination_id
belongs_to :rule
end
The problem is: is right to add two belongs_to to the same class using different foreign_keys? I tried all combinations like:
belongs_to :sources, :class_name => :network_object, :foreign_key => :source_id
but no success.. anything that i am doing wrong?
