Question

I have two tables:

tags
---
id
name
etc..

tags_synonyms
---
tag_id
syn_id

The syn_id is the synonym tag’s id, and the tag_id reflects the “root” tag that will actually be used. The synonyms exist only to provide alternative spelling/etc for tags to reference and find the root tag through. (please correct me if they should be stored in a separate table)

So I created a model Tag in Yii, but I’m not sure how to setup the relationships for it.

What I want to be able to do is do:
$tag->synonyms, and $tag->root to grab all synonyms and the one root tag respectively.

How would I setup the relationships for these two things?

Answer 1

I ended up just adding a linked_to root word column to the tags table and using that to reference the main word from the synonyms.
