Conditional relation
- by Lowgain
I've got a model like this:
Stem
-id
-etc
And then I have
Stemrelation
-stem_id
-related_stem_id
-active
I can get the related stems with the following relations
class Stem < ActiveRecord::Base
has_many :stemrelations
has_many :related_stems, :through => :stemrelations
end
class Stemrelation < ActiveRecord::Base
belongs_to :stem
belongs_to :related_stem, :class_name => "Stem", :foreign_key => "related_stem_id"
end
But now I'd only like to get the active relations.
I tried adding this to the Stem model:
has_many :active_related, :through => :stemrelations, :source => :related_stem, :conditions => {:active => true}
but this gives me an error becasue it tries to check the active flag on the stem model instead of the stemrelation. What do I change here?
Thanks!
