Rails - Jul 2007 - has_many_and_belongs_to_"one"? beginner question, go easy on me ....

Greetings. I am new to RoR, and to programming in general, so I
apologize if the solution is trivial.

My goal is to keep track of the 5 most common "Tag_Relationships" in a
tagging scheme. This would let me ask such things as "what tag
accompanies the tag ''computer'' most often, second most
often" etc.. I
figured this might be easier than storing an Array with the last_five
per Agile Web Development edition 2. I chose to use the acts_las_list
feature.

my question involves two models

Tag
...
has_many :tag_relationships, :order => :position
validates_uniqueness_of :name

Tag_Relationship
belongs_to :tag, :foreign_key => ''related_tag_id''
acts_as_list :scope => :tag
validates_uniqueness_of :tag_id, :scope => :related_tag_id


Questions. Something looks fishy to me in the belongs_to for
Tag_Relationships. I had to do this to get it to work, but really, the
tag_relationship belongs to the original tag, not the referred tag.
What is the correct way to use has_many / belongs_to in this case? I
would like to be able to do the following

t = Tag.find(1)
trs = t.tag_relationships

and then iterate over the collection and get the name for each
referred tag. My tag_relationships table is as follows

  create_table "tag_relationships", :force => true do |t|
    t.column "tag_id",              :integer
    t.column "related_tag_id",      :integer
    t.column "position",            :string                #ranking
for this particular tag
    t.column "relationships_count", :integer, :default => 1   
#number
of times this relationship has been recorded
  end

Thanks in advance

John

Well, I did not use act as, but I know you can do this...

t = Tag.find(1)
trs = t.tag_relationships

...when you use has_many and belongs_to :)
