can I fake has_one :through?
...a single RuleSpace. Going the other way, given a RuleSpace I should
find many Subjects.
I''m thinking the model definitions should look like this:
class RuleSpace < AR::Base
has_many :rules
has_many :subjects, :through => :rules
end
class Rule < AR::Base
belongs_to :rule_space
belongs_to :subject
end
class Subject < AR::Base
has_one :rule
has_many :rule_spaces, :through => :rules
end
I''m not sure at all that a call to Subject.rule_spaces will return
only a single element. Will #has_one enforce this? Is this legal?
